Cement particle boards (DSP). Cement particle board - where to apply a universal material? CSP plate technical data application

When performing activities related to the improvement of an apartment, a private house or the implementation of major repairs in new buildings, there is a need to level the floor. With limited deadlines for performing work, it is problematic to pour a cement screed that dries out for a long time. Cement-bonded particleboard can significantly reduce the duration of repair work and ensure the ideal flatness of the floor surface. Let us dwell in detail on the characteristics, advantages and disadvantages, as well as the specifics of the use of plates.

The composition of the DSP board and production technology

While searching for building material, developers must have come across the abbreviation DSP.

The abbreviation stands for cement bonded particle board made from the following components:

Portland cement brand M400 and above. The concentration of cement, which acts as a binder, is 60-65%;
wood chips, introduced in the amount of 20-24%. Used chips of coniferous trees with a size of 60-90 mm;
special additives, due to which the DSP board has increased tensile and compressive strength. The share of additives is up to 2.5%;
water in an amount of 8-8.5%, added when mixing dry ingredients to achieve the desired consistency.

Characteristics of cement-bonded particle boards are almost universal

The technology for the production of DSP panels provides for the following operations:

Loading into the mixer of aqueous solutions containing special components that increase the strength and water-resistant properties.
Addition of wood chips mineralized in modified aqueous solutions.
The gradual introduction of Portland cement and water, followed by mixing the mixture until a homogeneous consistency.
Supply of the cement-bonded mixture to the pressing equipment with the production of finished products at the output.

Due to the increased pressing force, there are no voids inside the chip-cement massif. The resulting product, which is based on wood shavings and Portland cement, is a thin sheet with a smooth surface, which has increased strength.

Cement particle board - use in the construction industry

DSP plate is used to solve various construction problems. Floor application is not the only area of application for cement bonded particle boards. An expanded range of products allows you to arrange the floor for every taste.

DSP is used for sheathing frame houses, while the slab serves as both a binder and a cladding

The technical characteristics and properties of cement-bonded particle board ensure its competitiveness with other building materials, as well as an expanded scope.

This allows the plates to be used for various purposes:

for walls, the DSP plate is used as a finishing material. Increased moisture resistance and a flat surface of the plates allows it to be used for facade restoration of buildings;
interior decoration and arrangement of partitions between rooms. It is easy to apply decorative finishes to smooth panels, as well as to glue wallpaper;
production of prefabricated or stationary formwork for pouring the foundation. Smooth end surfaces of the plates make it easy to dock and seal the gaps.

The absence of harmful reagents in the composition of the plates allows them to finish industrial and residential premises. The garage and workshop, after finishing with DSP panels, will acquire a modern look. It is well applied to the DSP panel tiled plaster, provided that a reinforcing plastic mesh is used.
Chip-cement panels are used in construction to solve a set of problems, significantly reducing the complexity of the work compared to traditional methods. Modern building materials not only reduce labor costs, but also reduce the estimated cost of construction activities.

Technical characteristics and features of the DSP board

The advantages of building materials are influenced by the manufacturing technology and composition of the DSP board, which consists mainly of cement and chips. What are they?

The frame for the DSP needs a serious, capable of withstanding heavy loads

Compared to traditional chipboard, modern material has improved characteristics:

increased margin of safety;
long period of operation;
resistance to moisture;
the ability to keep warm in the room;
high soundproof properties.

DSP plate is used in various climatic zones, while maintaining operational properties.

With a sheet width of 125 cm, the plates differ in overall dimensions and other characteristics:

length, component 240-320 cm;
width in the range from 0.8 to 3.6 cm;
specific gravity equal to 1.3-1.4 t/m3;
humidity not exceeding 12%;
roughness value at the level of 80 microns.

DSP boards for the floor, when absorbing moisture as a result of an unforeseen situation, swell by no more than 2%, which is extremely insignificant. Depending on the specific application, the boards are produced with a rough and smooth surface. The properties of the panels allow laying on the surface of various types of finishing coatings, as well as paints and varnishes.

Cement particle board is wood shavings (respectively, it is positioned as particle board), pressed in a special way and treated with cement mortar

Advantages and weaknesses

Cement floor boards, like other building materials, have advantages and disadvantages. Main advantages:

environmental cleanliness associated with the absence of harmful substances in the formulation;
resistance to the development of microorganisms, the formation of fungus and mold;
increased resistance to moisture in comparison with chipboard;
preservation of working properties with significant temperature fluctuations;
resistance to high temperatures, as well as open fire;
affordable price level, allowing the use of the material with a limited budget;
increased strength properties, allowing to perceive the acting loads;
ideal flatness of the plates, which does not require special alignment;
resistance to aggressive liquids, as well as chemicals;
the ability to effectively absorb external noise, providing comfort in the room;
improved thermal insulation characteristics, contributing to the reduction of heat loss;
ease of installation work, allowing you to install on your own.

Weaknesses of plates:

increased weight of building material, which makes transportation and installation difficult;
increased dust formation when cutting building materials into blanks;
the need to use personal protective equipment to protect the respiratory system and eyes from dust.

Recently, they are increasingly used as a base for finishing.

Due to a serious set of advantages, particle-cement boards are popular in the construction industry. In terms of most characteristics, sheet building material successfully competes with particle boards, wood-fiber panels and drywall. Having given preference to DSP plates, it is easy to quickly complete the installation and save money.

DSP plate - application in thermal insulation measures

When solving problems of thermal insulation of CSP buildings, the slab is used as a sheathing material.

Its fastening is carried out with the help of hardware. Sheathing is made from different sides:

outside the building on a pre-installed crate or on a special mastic;
indoors on a wooden or metal frame, as well as on the surface of the walls with glue.

Decorative finishing can be carried out immediately after the completion of installation activities.

Cement particle board - floor application

The main advantages of CSP are high strength and durability.

The use of building materials consists in laying finished panels on various types of bases:

a flat surface of a wooden or cement floor;
wooden logs installed at regular intervals.

Ceramic tiles can be glued to the surface of the plates, flooring can be laid, as well as laminate or parquet. The properties of the material are preserved for decades, subject to the installation technology.

Cement particle board - choose the material for the floor

Cement particle board is selected depending on the complexity of the tasks to be solved:

when mounting panels on logs, material 2-2.6 cm thick is used;
when laying on a cement base, the minimum thickness is 2.4 cm.

When purchasing floor tiles, pay attention to the following points:

availability of a certificate of conformity;
absence of cracks and defects;
flatness and roughness of the surface;
manufacturer's image.

Also check the availability of a sanitary and hygienic certificate confirming the environmental friendliness and harmlessness of products.

The surface of the cement board is smooth and even, which makes it very popular with finishers who use it as a base for decorative finishing.

We are preparing for the arrangement of the coating from the DSP boards

The process of surface preparation for the formation of a rough base from DSP panels is simple and consists in the following activities:

dismantling rotten boards, logs and replacing them with dry wood products;
careful sealing of cracks with wood putty;
coating a wooden surface with a primer that increases adhesion;
restoration of the surface of concrete bases and repair of defects.

The optimal solution is to lay the slabs on the beams with an interval between supports of 50-100 cm. When installing the panels on the logs, waterproofing material should be laid and thermal insulation should be performed.

To perform the work, prepare materials and tools:

bars with a section of 15x10 or 5x10 cm;
cement particle boards;
antiseptic impregnation for wood;
waterproofing materials and insulation;
hardware for assembling the supporting structure and fixing the plates;
electric drill and hacksaw.

After completing the preparatory activities, proceed to the arrangement of the floor.

To avoid deformation during operation, gaps are left between the plates.

The sequence of actions for the construction of the floor from DSP boards

Consider how the slab is laid on the balcony of the DSP. Follow the sequence of actions:

Lay a layer of heat insulator at the locations of the bars.
Install logs with an interval of 0.3-0.4 m parallel to the wall.
Fasten the cross bars with screws and angles.
Fill the space inside the lattice structure with insulation.
Cut the slabs into blanks of the required dimensions and lay them across the joist.
Fasten the particle boards to the joists with self-tapping screws.

At the final stage, it is important to carefully seal the seams using an adhesive composition.

Cement particle board - laying specifics

When performing work, observe the following recommendations:

treat wood with antiseptic solutions or used oil;
use square wooden beams with a side of 5 cm when laying the slabs on a concrete base;
control the horizontalness of the surface of the wooden frame and the laid slabs;
leave expansion gaps around the perimeter of the base formed from the slabs.

Pay attention also to the correct preliminary cutting of the material before starting work.

DSP plate will facilitate the formation of even bases, will reduce the duration of work and reduce costs. Using building materials, it is easy to build ceilings for a house from foam blocks. Thinking about it, consider using DSP panels. With the help of plates you can perform. Such a base and the Swedish foundation slab are comparable in terms of thermal insulation properties. Being engaged in construction, it is worth studying the difference between PC and PB plates. It is possible that this will come in handy when choosing a material.

For comparison with other materials, we propose to use such characteristics as:

fire safety;
ease of installation;
resistance to mold and disease;
reviews of builders;
feedback from residents and homeowners.

Fire safety and flammability class

In this parameter, DSPs are superior not only to polymeric insulation and PVC, but even to wood concrete. TsSP is assigned a flammability class - G1, that is, they are slow-burning. Due to the large proportion of cement, each of the chips is surrounded by a cement stone, so to start the pyrolysis process in wood close to the surface exposure to a temperature of 500 or more degrees for half an hour is necessary.

As soon as the thermal effect is eliminated, the pyrolysis process is quickly completed, because close contact of many chips is necessary for the start of a self-sustaining reaction.

If the temperature exceeds 700 degrees, and this effect lasts more than an hour, then the pyrolysis of the chips begins throughout the entire depth of the plate.

At this temperature, any building materials sharply lose strength, and concrete is completely destroyed. Therefore, after a fire of such magnitude, the house cannot be repaired, except that the fire was local in nature and burned out only a small area of the house.

Even the start of the pyrolysis process does not lead to the release of particularly toxic substances, because the main components of pyrolysis gas (smoke) are:

nitrogen;
carbon dioxide;
carbon monoxide.

Only carbon monoxide is a serious danger, but, firstly, very little of it is released during pyrolysis, and secondly, during a fire, combustion occurs in conditions of lack of oxygen, so carbon monoxide is released everywhere in huge quantities.

Therefore, the DSP one of the safest in the fire plan of materials and is comparable to GKL and fiberboards. It is much safer than finishing from:

plywood;
boards;
wood concrete;
insulating fiberboards;
foams and plastics.

Ease of installation

Due to the high cement content of CSP much harder than most finishing materials.

The weight of thin sheets is 25-45 kg, so a minimum of 2 people are needed to work with them.

To work with thick sheets, 5-6 people are needed, because the mass of a sheet with a thickness of 26 mm exceeds 200 kg.

Cutting the material is also difficult, because you need to use high-speed circular saw and diamond-coated blade or carbide tipped.

Therefore, in terms of ease of installation, DSP is inferior to most finishing materials. After all, its weight, with equal dimensions and thickness, exceeds the mass of any other finishing material, including LSU and wood concrete.

Resistant to mold and disease

Due to the fact that the wood in the DSP does not have direct contact with air, it is less susceptible to mold and disease.

In addition, for products manufactured in accordance with the requirements of GOST, the chips are pre-soaked in a solution of lime or other reagents, increasing biological stability wood.

Feedback from builders and residents about wood-cement blocks

In order to collect the most reliable feedback on the characteristics, application and prices of DSPs, we turned to the forums, among the users of which there are:

professional builders;
experienced engineers;
owners of apartments and houses;
people with experience in self-repair.

Scopes of DSP

DSPs have been widely used in many construction areas due to their technical characteristics. Modern products based on cement and wood shavings compete with drywall, fiberboard and plywood.

Loft-style room

Finishing the facade of the DSP

Houses, the facades of which are lined with CSP, acquire an aesthetic appearance. The front layer of such products can have different designs. They imitate other finishing materials (stone, brickwork, plaster) or have a decorative rough surface made of stone chips of various colors and fractions.

The use of DSP for the floor

When laying DSP on the floor along the logs, it is recommended to choose a thickness of products from 24 mm in order to ensure sufficient strength of the floor covering.

Fastening on lags

When working indoors, it is necessary to carry out preparatory measures - to close the holes in the base, if any, fix the logs, put insulation and vapor barrier material.

Preparatory work before laying the DSP on the floor

Fixation of the plates is carried out using self-tapping screws, while the screw with a countersunk head must be immersed in the body of the wooden beam by 20 mm. The result is a perfectly flat subfloor with excellent performance.

frame construction

DSPs have proven themselves in the construction of frame-type houses. There are two options - the purchase of a ready-made house kit from SIP panels based on DSP or self-construction of walls, between which there is a mineral insulation. The plates are fixed on a wooden or metal crate, while the frame is sewn around the perimeter, and then window and door openings are cut out. The elements of the crate are installed in increments of 60 cm so that the insulation material can be firmly fixed between them. Plates are taken with a thickness of 10–16 mm, fixed with galvanized screws.

Interior finishing works

The environmental safety of cement-bonded particle boards made it possible to use them as a full-fledged finishing material inside premises for any purpose. Due to its high moisture resistance, this material has significantly replaced drywall, which is not recommended for use on walls in wet areas.

Leveling the walls and floor in the bathroom

DSPs are used for effective leveling of walls and their subsequent finishing with decorative finishing materials. However, DSP in some interiors (loft, industrial, high-tech, and others), where a raw concrete texture is appropriate, is used to create accent surfaces and even to cover entire rooms.

The accent wall in the bedroom at the head of the bed is made of cement panels

The fastening of the plates depends on the thickness and dimensions of the sheets, and, accordingly, their weight. Heavy products are attached to the crate, and light ones - with the help of a special solution or mastic.

Production of SIP panels from CSP

CIP panels made of DSP are a three-layer material, where an insulation made of expanded polystyrene, basalt fiber or polyurethane foam (PPU) is fixed between the sheets.

Appearance of sandwich panels

A common distinguishing feature of the material is its high fire and environmental safety. The possibility of rapid construction of a private house and significant savings on finishing facade work.

The use of DSP for formwork in monolithic construction

There are a number of advantages of this type of fixed formwork device in the production of monolithic works:

Reducing installation work and the total period of construction of the facility.
Surface ready for finishing.
High profitability of the construction of the facility as a whole.
Guaranteed to create a solid and reliable design.

Monolithic construction using fixed formwork from DSP

Mounting methods

DSPs can be mounted in various ways, depending on the purpose for which they are used. When finishing or insulating buildings, they are attached to a crate made of a metal profile or wooden bars with self-tapping bolts or nails. The arrangement of fixed formwork also involves frame erection (given the large weight of the plates, it, like the crate when finishing the walls, must be strong enough). In addition, the slabs can be laid on logs (when installing the floor) or rafters (under the roofing). When interior decoration, they are also can be attached to the wall with mortar or mastic.

Preparing for DSP Coating

Before starting work on arranging a rough coating from DSP, the subfloor must be properly prepared. For example, in the case of laying material on a wooden base, old or rotten boards must be dismantled and replaced with new ones.

It is important to close all the cracks with putty, and the wooden base is primed for better adhesion to the glue, on which the slab coating will be mounted.

If the installation will be carried out on a concrete base, then it should also be carefully inspected for damage and repaired if necessary. Also, if there are strong horizontal deviations, cement mixtures are leveled. In the case of laying DSP on the ground, a preliminary leveling of the surface is necessarily carried out - this can be done by pouring a sand-gravel mixture 20 cm thick on the ground and ramming it.

The process of building a gazebo with a DSP floor

The best option is to lay DSP boards on logs. In this case, if it is planned to install the base directly above the ground, the supports for the logs are installed on the ground, and hydro and thermal insulation is also laid. The distance between the supports can vary from 0.5 to 1 m - this figure depends on the thickness of the timber used for the logs.

Materials and tools that need to be prepared for working with DSP:

timber for lags (section 150x100 or 50x100 mm);
DSP boards in the required quantity;
antiseptic solution for timber;
sawing tool (for example, a hacksaw);
materials for waterproofing and insulation;
measuring instruments (tape measure, pencil);
fixing material;
drill.

How to paint DSP board

To give DSP boards an attractive appearance, the easiest way is to paint. After appropriate preparation of the surface, two coats of paint are applied with a roller or. Most often, in order to paint the DSP, they use:

Acrylic paints . This paint has good adhesion and is highly wear resistant. If financial possibilities allow, it is better to use paints that include a solvent, but water-soluble facade acrylic paints, if properly applied, will last from 3 to 5 years.

latex paint . This coating is resistant to alkaline and mild acid solutions, easy to wash and mechanically clean with detergents. Besides. Painting work can be done independently, which will save a significant amount.

silicate paint . The use of this type of coating has high adhesion, their vapor permeability provides optimal conditions for air circulation, which prevents the appearance of mold and other fungi. The coating is not afraid of atmospheric influences and detergents, and the service life will satisfy even the highest requirements.

Before proceeding with the painting of the CBPB, it should be taken into account that the use of alkyd paints is undesirable, since cracking and peeling of the coating may occur upon direct contact with alkalis.

1 What are such plates made of, are additives needed?

DSP is a multi-component sheet building material, in the manufacturing process of which Portland cement and wood shavings are used. In addition, the composition of the plate includes special chemical additives that allow the base materials to coexist without any problems. Indeed, under normal conditions, wood is not friendly with cement, which provokes excessive moisture and the associated warping and decay of the material.

For the manufacture of CBPB, Portland cement and shavings are used.

The use of special additives (up to 2.5–3% of the total volume) eliminates the negative consequences of the proximity of wood and cement, giving CBPB such useful properties of the first and second components as heat resistance and fire resistance. Moreover, due to the percentage ratio - 24% of wood accounts for 65% of cement - the plate acquires other positive qualities: high strength, frost resistance, soundproofing properties, vapor permeability and complete disregard for the material by both insects and rodents.

In addition, at the same time, a wooden and cement board demonstrates such qualities as resistance to fungi, moisture resistance, resistance to temperature shrinkage and compatibility with most finishing materials, which is explained by enviable adhesion. At the same time, chemical additives in DSP do not belong to environmentally harmful materials, since they do not contain either asbestos or formaldehyde.

Specifications of the DSP

In the manufacture of high-strength cement compositions are mixed with wood shavings of various fractions, water and a number of chemical reagents (for example, liquid glass or aluminum salts). Reacting with wood shavings, chemicals mineralize it, thereby increasing the strength and durability of the board.

Layering is the main quality of the boards, which guarantees their high quality and special strength. The formation of the slab structure occurs in such a way that large fractions of chips are located inside, and small ones are outside. After the preparation of the cement-bonded mass, its layers are placed in special molds under the press, from where the finished multilayer DSP with a smooth surface on one side comes out.

DSP: the technical characteristics of the plate are such that it does not require the application of finishing putty. It is sufficient to paint the slabs after placement. In some cases it will be sufficient to apply a thin coat of primer before painting.

CSP floors laying nuances

In general, the installation of DSP boards is carried out in exactly the same way as the laying of OSB boards.

During the work, it is important to follow a few rules, and then the base of the floor will turn out to be of the highest quality: a wooden beam for a log must be treated with compounds that prevent rotting

Special compositions can be replaced with engine oil;

a wooden beam for a log must be treated with compounds that prevent rotting. Special compositions can be replaced with engine oil;

Wood preservatives

when installing plates on a concrete screed for a log, you can use a beam of a smaller section - up to 50x50 mm. This will save usable space;
when installing the log, you should monitor their level - it must be strictly horizontal;
before installation, DSP boards are laid out on logs - this will allow you to determine which of them need to be trimmed if necessary;
glue must be well mixed before use;
Compensation gaps along the walls will allow avoiding deformation of the DSP base.

Another example of the use of DSP

DSP - the material is not bad enough, if you use it to create an even base. It is not difficult to work with him, but due to the large mass of sheets, it is better to get an assistant.

Mounting Features

Boards based on a cement-bonded mixture are easy to process. For cutting, you will need a hacksaw with fine teeth. Large teeth contribute to the formation of dust, makes the edges of the part uneven, so this tool is not suitable for sawing DSP.

When arranging a dry screed, a concrete or wooden coating is used as the basis for the slabs. Also allowed is the option of laying sheets on a frame, the cells of which are pre-filled with insulating material (mineral wool, foam plastic, expanded clay, and another type of dry filler).

The plates are fixed with self-tapping screws or with the help of an adhesive mixture. The adhesive must be evenly distributed over the surface of the material with a notched trowel, leaving no gaps. This will help to avoid deformation of the material.

It is also important to generously fill the joints with adhesive to obtain a monolith. Self-tapping screws are screwed in at intervals of 35-50 cm

When facing the DSP of the outer walls of the building, an installation method is used that provides for the arrangement of the crate. Frame parts can be wooden or made of metal profiles. When choosing a tree, it is recommended to pre-treat it with an antiseptic solution to protect it from premature aging and microbiological processes.

To create a thermal protection of the dwelling, it is recommended to lay heat-insulating material between the walls of the house and the DSP. Preference should be given to basalt wool, which has a good rate of vapor permeability (the walls will breathe) and high resistance to moisture (low hygroscopicity will prevent moisture absorption into the layers of the heat insulator).

Fine finishing of slabs from a cement-bonded mixture provides for surface treatment with a primer, laying a reinforcing mesh and applying a layer of decorative plaster. The facade is painted in a color that echoes other architectural elements of the exterior.

Arrangement of the floor with the help of DSP

Let's consider the arrangement of the floor from the DSP on the logs using the example of a balcony.

Step 1. A layer of insulation is laid under the logs. Logs are installed parallel to the walls at a distance of about 30-40 cm from each other.

Logs installed on top of the insulation

Step 2 Cross bars are installed, crates are being created. Between themselves, wooden bars are connected using metal corners and self-tapping screws.

Cross bars are installed, the crate is ready

Step 3 The space between the lags is filled with insulating material.

Insulation laying

Step 4 DSP slabs of the required dimensions are laid across the longitudinal logs. The width of the piece of material should be slightly less than the width of the balcony (by 5-10 mm).

Laying DSP boards

Step 5 The plates are fastened with self-tapping screws on the logs. The gaps between the DSP boards are sealed with adhesive.

DSP in the process of creating the foundation

Cement- and chip-based slabs can be used to create formwork that aids in pouring foundations. The thickness of the material depends on the required dimensions of the foundation and ranges from 16 to 26 mm.

Strengths of CSP formwork.

Simplicity in the installation of plates by an order of magnitude reduces labor costs and reduces the time of work, thus reducing the cost of the process of pouring the foundation. A special paint can be applied to the outside, after which it will acquire the properties of vertical waterproofing. Due to the high strength of the plates, the formwork is resistant to deformation during pouring and drying of the concrete solution.

The versatility of DSP allows the use of this material in the construction of frame-based housing, for leveling floor and wall coverings, as well as during the installation of soft roofs in buildings of any type. CSP floor slab gets good reviews from builders all over the world due to its high quality material and excellent performance.

Cement particle board floor application

The main advantages of CSP are high strength and durability.

The use of building materials consists in laying finished panels on various types of bases:

a flat surface of a wooden or cement floor;
wooden logs installed at regular intervals.

Ceramic tiles can be glued to the surface of the plates, flooring can be laid, as well as laminate or parquet. The properties of the material are preserved for decades, subject to the installation technology.

Scope of application of DSP boards

As mentioned above, DSP boards, the use of which ensures high mechanical strength of the created structures, are widely used in construction, repair and finishing works, in particular:

When making formwork foundations and other monolithic reinforced structures. The use of DSP greatly simplifies the installation process, in addition, this design prevents concrete leakage and ensures the formation of smooth side walls that do not require subsequent plastering.
For wall cladding and construction . In most cases, DSP sheets are attached to a pre-assembled metal or wooden frame. The thickness of the sheets in this case is from 8 to 12 mm. For fastening, self-tapping screws are most often used, it is also possible to use screws or nails as fasteners. In some cases, when leveling walls, special adhesive polymer mixtures can be used.
The use of DSP floor slabs provides high mechanical strength, as well as high rates of heat, hydro and sound insulation. The thickness of the material is selected based on the existing loads and the distance between the lags, however, the use of DSP boards with a thickness of less than 14 mm is not recommended.
Application for facade at home allows not only to significantly reduce the time for exterior finishing work, but also provides high-quality waterproofing of the main walls. Another advantage is that when using DSP, the characteristics of the material allow you to create various types of ventilated facades. As for the thickness of the sheet, for outdoor work it can vary from 12 to 14 mm.

Plate production

The production of DSP consists of the following steps:

Aluminum, liquid glass, various salts are part of aqueous solutions that are loaded into special mixers.
Mineralization of raw materials occurs with the gradual introduction of wood shavings into these solutions, consisting of different-sized fractional inclusions.
Then cement and a little water are introduced into the composition.
The mass is thoroughly mixed to obtain a homogeneous consistency, sent under a powerful press.
The output is thin, but strong, with a smooth surface product.

The smooth surface of the plate is obtained due to the special distribution of chips in its structure - larger fragments are inside the product, and small ones are on the surface. In the production of DSPs, there are no voids in them. Another advantage is that the product is not subject to additional leveling, but can be immediately used for the manufacture of a subfloor and serve as a high-quality, even base for laminate, tile and other types of topcoat.

DSP production technology

From the name itself, it becomes clear that the main components of this material are cement (65%) and wood chips (24%). All this is mixed with water (8.5%), and various additives are added to the resulting mixture to improve the technical characteristics of the plate (2.5%).

Two types of chip material are used in the production process of DSP boards. They differ in size: small and medium. The plate itself has a three-layer structure, so medium-sized chips are poured into the second layer, and small chips into the first and third. The production process itself takes place in the following sequence.

Chips are mixed with hydration additives.
Cement grade M500 is added to the resulting mixture.
Water pours in.
The solution is thoroughly mixed until a homogeneous mass is obtained.
The first layer with small chips is poured into the mold.
The second layer with medium-sized chips.
And the third layer.
Pressing is in progress.
After that, the semi-finished material is heated to +90C for eight hours.
Then, within 13-15 days, it dries in natural conditions.
After that, depending on the batch, it is either polished or simply stored.

Cement particle board applications in construction

DSP is a cement-bonded particle board, and the name fully reflects the composition of this material. DSPs are made from a mixture, the components of which are wood chips and cement compositions.

What is DSP and OSB? What is the difference?

The composition of the building material includes:

wood chips with fractions of various sizes - 24%;
water - 8.5%;
special additives - 2.5%;
Portland cement - 65%.

DSP boards for outdoor use

The production process is quite simple - DSP is done as follows.

Special water solutions are loaded into special mixers, which include various salts, liquid glass and aluminum.
Further, wood shavings with fractions of different sizes are gradually added to these solutions - mineralization of raw materials occurs.
Cement is added to the resulting composition and a little more water is added.
The mass is subjected to thorough mixing until a homogeneous mass and then goes under a powerful press.

GOST 26816-86

The result of this production chain is the finished cement particle board, which is quite thin and has a smooth surface. A large amount of cement in the composition allows you to create a fairly durable material. By the way, inside the plate, the chips have b about Larger dimensions than outside, due to which the smoothness of the surface of the finished material is achieved. DSP does not need to be further leveled after laying, making the material excellent for creating a rough floor covering for laminate, tile and other types of finishes. Also, voids are not formed inside the DSP during production.

Cement particle board production

On a note! Wood shavings are also used as a raw material in the production of chipboard, fiberboard and OSB boards. The technologies for the production of these materials are somewhat similar to the technology for producing CSP boards.

Comparative table of performance characteristics of wood-based materials

DSP boards are widely used in construction. They can be used to decorate the facade walls of houses, they are used to create various partitions inside the premises. The material is suitable for use in restoration purposes and for interior finishing work. At the same time, it is suitable for apartments and private houses.

DSPs are used in construction for many purposes.

DSP plate is distinguished by high environmental friendliness, as it is created from natural materials and practically does not contain additional chemical ingredients. That is why the stove is recommended for use both in residential premises and in production.

Cement particle board (DSP)

The use of cement particle board is an opportunity to abandon the laborious pouring of a cement screed to create a base. Building material allows you to reduce labor costs and spend less money from the budget planned for leveling the floors for laying the finish coating.

Like it or not, CSP is a concrete stone filled with shavings (wood filler). Therefore, when the question is raised, how to process this type of material, one cannot mention a hand tool. Cutting and drilling can only be carried out with an electric tool.

At the same time, it is better not to use a jigsaw, although some craftsmen manage to cut plates of small thickness with such a tool. You just have to change the file often - every 5-7 m. Therefore, the optimal solution is a disc cutting tool.

The easiest way to cut DSP is with a circular saw with a diamond blade.

As for the disk, there are two options:

Diamond coated disc with cut out segments. This disc is used for dry cutting. Here you can use discs for cutting stone, concrete or brick - they all work.
Pobedite-coated discs for cutting wood. DSP is not the most durable material in terms of comparison with stone, so such a tool will cope with it.

As for power tools, most often craftsmen use a grinder or a circular saw (parquet).

Attention! It is easier to cut slabs with a DSP circular saw because the power tool has a support bar. It is she who allows you to clearly orient the disk in a perpendicular plane to the sheet, and as the final result - an even cut of the material

DSP slabs can be cut with a grinder with a cutting diamond disc installed on it

As for drilling holes in slabs, either metal drills or drills are used for this.

Types and characteristics

There are 3 types of DSP:

fibrolite- heat-insulating material based on long-fiber shavings (“wood wool”). Soft, easy to process, resistant to biological factors;
wood concrete- made from sawdust and small chips. It has a wide range of applications (thermal insulation, decoration, material for wall partitions, etc.);
xylolite(slab and cast). It has high strength, thermal insulation qualities and a wide range of colors, it is used as a floor covering.

Due to their water absorption, the plates increase in size, so a gap is required when installing between them.

Kinds

There are three types of DSPs. Studies of the material showed with accuracy that each of them does not lose its valuable properties even in the process of multiple cycles of a significant increase in temperature and subsequent defrosting.

Resistance to fire and especially humid environment, negative biological factors was also confirmed. But each type of plate has its own characteristics, consisting in the method of production, the difference in raw materials, the characteristics of the finished product and the scope. Among the types you can specify.

1. Fiber mat. Its basis is the so-called wood wool, which is a long-fiber shaving. The composition also includes inorganic binders.

Wood tapes obtained on special machines are impregnated with solutions of calcium chloride and liquid glass. Raw materials pressed in molds are subsequently dried. The thickness of such plates can reach 150 mm, but there are a number of much thinner parameters.

These building elements, characterized by considerable strength, are excellent for thermal insulation. Similar material is also used as acoustic.

It is easy to process and soft, because of this, it is in demand for multifaceted repairs, as well as works on the reconstruction of various structures. During construction operations with plates, due to their low weight, lifting equipment is not required; therefore, their use is very economical.

2. Arbolit. It is classified as lightweight concrete and contains small shavings, sawdust, reeds or rice straw. The most high-quality plates of this variety are made from wood chips.

If the basis of the composition is wood shavings, then the material is usually called wood concrete, if sawdust - sawdust concrete. The two types mentioned have somewhat reduced performance compared to the first one mentioned above.

They are heavier, denser and subject to unpleasant deformations, but also cost somewhat less. The scope of arbolite is quite wide. But basically it is in demand as a material for low-rise private construction, it is especially popular in the manufacture of wall partitions, as well as for decoration and thermal insulation.

3. Xylolite is most commonly known in the application as a coating DSP for floor. Plates, similar to those previously described, are made from wood waste, differing from other types in production technology. On sale, the presented assortment pleases with a variety of colors.

The material is distinguished by excellent thermal insulation qualities and increased strength. It does not burn in an open fire, but only gradually chars; even when boiling, it does not soak in water and is slightly thermally conductive; has an enviable elasticity and is hard as a stone, but at the same time it is easily processed like a tree: it is drilled, planed and sawn. In application, in addition to the above, it is excellent as a sheathing for stone, covering stairs, window sills, roofs.

An important characteristic is the weight of the DSP board. Such indicators are simply necessary to know during construction and other works.

The specified data is very useful in the transportation of goods and at the time of installation work. The mass of one module directly depends on the thickness and, knowing this indicator, it is easy to calculate it. After all, for every 10 mm there is a tiled weight of approximately 54 kg.

Installation work than sawing DSP

You should not try to cut the DSP with a hacksaw - this is a thankless task, the process is long, and the result leaves much to be desired. You can use a jigsaw or grinder.

Article

Cement-bonded particle boards (DSP) are a whole class of building materials with different characteristics.

They are used for various purposes, using the advantages that they have over traditional finishing and structural materials.

The scope directly depends on the type and density of the DSP, so we recommend that you read the articles:

DSP production: step-by-step guide, regulations and necessary equipment.
Fiberboard.

In these articles, we talked about the different types of cement particle board, as well as the differences in the original components and their proportions.

Even with the same density, the main parameters of TsSP-1 and TsSP-2 boards are very different from fiberboard boards of any type. This due to different amounts of cement, as well as different requirements for wood filler.

What can DSP be used for?
how to choose materials for a particular application;
what are the advantages of properly selected plates over other materials;
how to fasten the panels to walls or to a wooden floor, how to saw them, glue them together, prime them, and how to handle DSP differently;
how to lay tiles on the DSP;
how to paint the facade of a building on which DSPs are installed, and how to protect this material from moisture and other negative factors.

Here are the main areas in which cement bonded particle boards can be used:

structural elements (walls and partitions);
insulation of walls, floors and ceilings;
soundproofing;
exterior and interior decoration;
fixed insulating formwork;
creation of greenhouses, beds and other areas.

Structural elements

From the DSP, you can create various partitions that divide the room into separate zones or parts.

Due to the high rigidity and strength, the plates in this area are not inferior to materials such as:

wooden plank;
plywood;

but to create partitions and walls according to technology without a supporting frame, only cement-bonded particle boards with a density of more than 1000 kg / m 3 are suitable, and the best results are shown by TsSP-1 and TsSP-2.

Fiberboard slabs with equal density are less durable, because they contain less cement.

However, full-fledged large-sized walls cannot be made from this material due to the size of the sheet, because the maximum width does not exceed 125 cm, so the sheets will have to be stacked on top of each other.

Therefore, to create full-fledged walls and large-sized partitions support frame required, but the same limitation applies to other structural elements comparable in size.

The exception is when it is possible to place cement-bonded particle boards vertically and securely fasten them from above and below.

Moreover, such a wall will only perform decorative function and is not designed for any kind of force impact.

With a slab thickness of 30–50 mm, a door or an arched opening can be cut into a wall of this design, as long as its width does not exceed 1.5 of the width of the DSP slab.

If the width of the section to be blocked does not exceed the width of one sheet, and force is excluded on it, then a material with a thickness of 10-15 mm can be used (when using fibrolite plates, the thickness must be increased to 20 mm).

At the same time, in comparison with other structural materials of the same thickness, DSP will provide much higher level of noise and heat insulation.

Insulation for facades and walls of the house, floors, ceilings

To insulate the house, you can either use the DSP inside or sheathe the facade of the house with this material. As a heater, it is better to use cement-bonded particle boards of any type. with a density of 250–350 kg / m 3, however fiberboard is more efficient due to less cement.

Despite the low density, the strength of sheets of any thickness is sufficient to attach to the wall both with glue and with anchor nails.

DSPs are somewhat less efficient than foam plastics (the thermal conductivity of plates is 0.06, foam plastic is 0.04), but they freely pass water vapor, due to which a favorable dry climate is always maintained in the premises.

DSP is only slightly inferior to mineral wool (the thermal conductivity of plates with a density of 300 kg / m 3 is 0.06, and wool is 0.05), but an increase in humidity does not affect their characteristics.

In addition, their can be installed on flat surfaces without a special frame, and to protect against precipitation, a thin layer of plaster or even waterproof, vapor-permeable paint is sufficient.

Despite the fact that polyurethane foam is easier to apply, expensive highly specialized equipment is required to work with it, the price of which starts from 40 thousand rubles.

Besides, polyurethane foam does not pass water vapor at all, therefore, after warming them in houses with a not too good ventilation system, the climate becomes damper, and mold and rot appear.

The costs for working with any type of DSP are much lower, and the equipment can be used for many other jobs.

When insulating ceilings, cement-bonded particle boards are hemmed from below, using glue and anchor nails or self-tapping screws for this. However, this application method can only be used in houses and apartments with strong ceilings and reliable ceiling filing.

Fiberboard slabs with a density of 250-350 kg / m3 are best suited for these works, because they contain more wood than products of the TsSP-1 and TsSP-2 brands. The maximum thickness of the plates depends on the strength of the floor and the ability to securely attach the insulation to it.

With the help of this material, it is possible to completely make and mount the roof of the house, as well as to build the whole house as a whole.

To insulate the floor, the slabs are laid either on a concrete screed or on a rough floor.

If the base is not too flat, then to level the floor it is desirable to pour a layer of solution, this will maximize the potential of the DSP.

After all, all materials of this type, made according to GOST or international standards, are the same in thickness and have a smooth surface.

Thanks to this, it will be possible to lay parquet, laminate or linoleum on them. without additional layer. The optimum density of the material of the TsSP-1 and TsSP-2 types is 500 kg/m 3 , the optimum density of the fibrolite is 800–900 kg/m 3 .

Quite often, the technique of laying DSP on the floor along wooden logs is used, and the thickness and density of the plates necessary to ensure the strength of the floor in the house, in this case, will depend on the distance between the installed logs.

Laying DSP on the floor, including wood, under tiles is an ideal option in bathrooms.

To start the installation of tiles, it is enough for cement-bonded particle boards apply a couple of coats of regular primer to improve adhesion.

If it is necessary to insulate the base of the warm floor, including if it is mounted under the tile, then the density of the sheets depends on its design. If the heating element is walled up in a screed, then it is advisable to use plates density 300 kg/m 3.

If the heating element will be laid between wooden or aluminum supports, then it is desirable to use a material of the same density as for a conventional floor.

When insulating the floor with cement-bonded particle boards, it is necessary to ensure reliable waterproofing, since the water that has fallen under the front cover will be absorbed into the insulation, but it will be difficult to go back due to poor air exchange.

Long being in a state of high humidity will reduce strength particle board floor and will lead to the appearance of mold and rot in the chips, which will negatively affect its thermal insulation properties.

Soundproofing

Residents of Soviet-built multi-storey buildings suffer greatly from poor sound insulation, because in the apartments you can hear everything that happens at a distance of several floors. Often even residents of private houses are looking for ways to improve sound insulation to reduce the level of noise passing into the rooms from the street.

Low-density cement-bonded particle boards, although they are inferior to many modern materials with the same thickness, but due to the minimum cost and ease of installation on walls, floors, etc., they are very popular.

The most effective in this area are fiberboards of the GB-1 standard and their magnesite counterparts.

The maximum soundproofing effect is achieved not only by increasing the proportion of wood waste, but also located along the slab. However, slabs TsSP-1 and TsSP-2 with a density of 250–350 kg / m 3 also good for noise reduction.

To increase the soundproofing effect between the slabs and the wall/ceiling, lay a layer of felt 2–6 mm thick.

Sheathing the ceiling with slabs 2–3 cm thick and laying felt, you lower the level entering the apartment ten times the noise. At the same time, it is important to tightly join the plates so that there are no gaps between them, otherwise the effectiveness of such sound insulation will drop sharply.

For outdoor work and interior decoration

The purpose of exterior and interior decoration is to hide wall defects and make the exterior or interior more attractive. All types of DSP are well suited for rough finishing, over which a fine finish can be applied.

Cement particle boards of any type have high strength, however, material with a density of less than 700 kg / m 3 cannot be used for exterior decoration, and less than 1000 kg / m 3 for interior decoration.

As the density increases, the rigidity and strength of the product increase, which is especially important in regions with frequent strong winds.

Interior finishing material must withstand a screw with a small load, therefore, the use of low-density cement-bonded particle boards for interior decoration is unjustified.

In most cases, this finishing material must be attached to a special frame that compensates for the unevenness of the walls. In addition, the frame allows air to move under the finish, so that the condensate on the wall evaporates faster and does not increase the moisture content of the wall or finish.

If the frame is made correctly, then after installing the plates they form a flat surface, so it is enough to putty the seams between them with mortar or putty, after which walls ready for finishing.

The most effective as a finishing material are plates of the TsSP-1 type with a polished surface.

They are attached to the frame with the help of appropriate self-tapping screws - wood-carved screws are needed for wooden bars, self-tapping screws with metal thread are required for aluminum or steel profiles.

As an interior finish, chipboard-based sheets have a significant advantage - they do not emit toxic substances which cannot be said about:

plywood;
plastic;

The only materials that can compete in terms of environmental safety are natural board and real MDF, made without the use of glue.

However, they have serious disadvantages compared to cement-bonded particle boards:

less rigidity, forcing to increase the thickness of the finish;
much higher flammability;
higher price.

Therefore, as an environmentally friendly material for interior decoration, all types of DSP have no equal in the totality of all parameters.

do not emit toxic substances in normal circumstances;
able to withstand high temperatures for a long time before the start of the pyrolysis process in sawdust;
do not support combustion and go out after the disappearance of the source of open fire;
even during a fire, they do not emit toxic substances, with the exception of carbon monoxide and carbon dioxide, but any organic matter emits these substances during combustion;
albeit slightly, but they perform the functions of insulation and sound insulation.

For exterior decoration of the facade of the house, cement-bonded particle boards and panels of the TsSP-1 type with a density of 1100–1400 kg / m 3 and a thickness of 1 cm are most popular.

With the right selection of the distance between the slats of the frame, such a decoration of the house outside easily tolerates wind speeds of 40–50 m/s. An example of finishing the facade of the house is shown in the photo below.

Fiber cement boards of the same density must be chosen with a greater thickness due to the lower cement content, therefore, most often for outdoor work, a material with a thickness of 15–20 mm is used. He has the same resistance to precipitation and wind load.

Between the wall of the house and the finish, you can install an insulation made of chips and cement, which has excellent reviews, or another material.

Due to the fact that during rain water quickly drains from the surface of the panels for facade cladding, the panels do not have time to absorb a lot of water, so even in the event of a sharp drop in temperature after a long rain, they will not be severely damaged.

Treatment with hydrophobic paints for outdoor use and preparations that do not affect vapor permeability, further reduces the ability of the material to absorb water.

Thanks to this, DSP of any type as an exterior finish is in no way inferior to traditional plaster.

Thanks to such properties of the material, the ease of its finishing (painting), as well as the numerous reviews of residents, the facade cladding of the DSP house can be safely called the best option for the climatic conditions of many regions of Russia.

In addition, manufacturers also produce facade panels that do not require additional finishing for sheathing houses, including frame wooden, performing at the same time a decorative function.

For example, facade and plinth panels under a stone, under a brick, under a crumb and others.

Such facade panels are used to finish the foundation of the house, the basement, including on screw piles.

Do-it-yourself fixed insulating formwork

The construction of houses from monolithic concrete is gaining more and more popularity, because it allows you to build walls much faster than any other methods.

Fixed formwork not only creates a form for concrete, but performs an insulating function, thanks to which, after the concrete has gained full strength, the wall is completely ready for finishing and does not require additional insulation.

The only one competitor cement-bonded particle boards in this application – fixed formwork styrofoam(PPS), however, it completely blocks the vapor permeability of the walls, which is why problems begin in houses with a not very good ventilation system.

Unlike polystyrene formwork, which is supplied in small prefabricated blocks, cement particle board formwork must be made by yourself.

As in the case of EPS formwork, CSP formwork must be carefully reinforced with numerous bridges to avoid extrusion of the slab with concrete.

This is especially true in the case of using heavy concrete, but it will not be superfluous when pouring foam concrete.

In addition, it is necessary intensify formwork over the entire area with various pegs and struts, which protect it from shifting during concrete filling and compaction.

For the manufacture of formwork, it is desirable to use sheets density over 1000 kg/m 3, and the thickness of the sheet directly depends on the desired thermal insulation effect.

Therefore, sometimes they make a double formwork - they install an inner sheet of DSP with a density of 1200–1400 kg / m3 and a thickness of 10 mm, and a fiberboard sheet with a thickness of 50–100 mm and a density of 300 kg / m 3 is placed close to it.

When using foam concrete, this design will provide such a low level of heat loss that even in the conditions of the northern regions no additional insulation required.

However, fixed formwork made of DSP also has minus- her cannot be used below ground level, since under the action of groundwater, wood will eventually lose its thermal insulation properties, and the cement stone will collapse.

But as a formwork for the internal walls, the DSP has no equal, because after the concrete hardens, the wall surface is ready for fine finishing, and even has a slight, but heat and sound insulation effect.

Greenhouses and beds

Cement particle boards, even when buried in the ground, able to stand like this until destruction for several decades, due to which they are often used to create do-it-yourself or fencing greenhouses and garden beds. After all, boards without special treatment will rot into dust in 3-5 years, and DSP will last 20-40 years without requiring replacement.

Most often, plates are used for this. density over 1000 kg/m 3 and thickness 8–12 mm.

Another advantage of cement bonded particle board is that CBPB greenhouses and vegetable garden fences look very tidy due to the smooth walls.

The wagon board creates the same effect, but its service life and high price do not allow it to compete with DSP.

Chipboard, plywood and other similar materials also cannot compete with these boards, because even those that are called waterproof are quickly destroyed when they are in the ground.

With a small height of the walls, you can do without a frame, connecting the plates to each other using plastic corners, but if the height or length of the structure requires the use of several plates, you cannot do without a frame.

As a frame, you can use both boards impregnated with hydrophobic compounds (such compounds spoil the soil), and structures based on large diameter polypropylene pipes.

If the pipe diameter exceeds 30 mm, and the frame design is well thought out, then the greenhouse or garden bed is quite durable.

It is possible to reduce the diameter of the pipes by inserting pieces of metal or fiberglass reinforcement into them, however, in this case, it will be necessary to fix the DSP use jumpers of small length.

Due to the fact that the cost of a sheet rarely drops below 500 rubles, many prefer used cement-bonded particle boards that were dismantled during repairs.

Such DSPs do not have a very good appearance, and their strength is much less than new ones, but they are quite in demand for fencing beds and creating greenhouses, which can be concluded from the numerous reviews of gardeners. And you can buy them very cheap or receive as a gift.

In addition to the listed areas of application, DSPs, due to their properties and affordable cost, are also used to build baths with their own hands, including floors in it, cladding garages, sheds, building fences, mounted on the roof, etc.

Processing and installation of sheets

Cement particle board, in terms of its physical characteristics, is very different from most finishing materials, so its processing takes place according to a special algorithm and using special tool.

Violation of the work algorithm and the use of an inappropriate tool are often causes damage to the material. and the need to replace it, and given the considerable price of any type of DSP, including, for example, floor sheets or slabs for a brick or tile type facade, such an attitude turns out to be extremely unprofitable.

What to cut?

To cut this material you will need hand circular saw, equipped with a disc with carbide (pobedite) nozzles or diamond-coated teeth.

If there is no such disk, you can use a suitable size abrasive cutting disc for stone with a bore diameter of 32 mm.

If you need to cut a sheet or cut a rectangular hole in it, then lay it on a flat table so that the cutting line recedes 2–4 cm from the edge.

Mandatory for cutting use a respirator and goggles and don't forget to fasten the sleeves on your clothes. Place the saw sole on the sheet so that the blade is 3–5 mm away from it.

Turn on the saw, then smoothly move forward so that the blade goes exactly along the line of the cut. The speed of the saw movement depends on the density and thickness of the sheet, so be guided by your own feelings.

At normal speed, the sound of the saw motor does not change much, and minimal forward movement resistance.

If the sound changes (speed drops) or resistance increases, then you are moving the saw forward too fast, because of which the blade does not have time to cut through the cement stone normally. To reduce the amount of dust and improve the quality of the cut, you can pour water on the sheet along the cutting line.

If the size of the cut piece exceeds 20 cm on either side for thin slabs and 10 cm for thick slabs, then the assistant must support the cut piece so that it does not break off.

Need to be careful to keep your fingers out of the path of the saw.

To cut a round or oval hole, you must first draw it on the sheet, then fit a rectangle into it. Moreover, the distance from the picture to the edge of the rectangle should never be less than 3 cm.

If you know how to cut with a circular saw not from the edge of the sheet, then cut a rectangle with it, if not, then use grinder(angle grinder, angle grinder) with abrasive disc for stone.

Having cut out the rectangle, on the remaining parts of the plate inside the picture, mark parallel strips in 1–1.5 cm increments, extending from the edges of the rectangle to the edge of the picture. Cut through these strips, not reaching the edge of the pattern 3–5 mm.

Then cut through drawing sheet using an electric jigsaw with a diamond saw blade designed for cutting glass or ceramics.

This sequence of actions increases the time required to cut a hole, but greatly reduces the chances that you will ruin the material. Indeed, when cutting a hole with a diameter of more than 40 cm, there is a possibility that the cut piece will break off, and the fracture line will affect the remaining sheet.

If you are a skillful experienced finisher and therefore know how to work well with materials such as:

ceramic tile;
smooth slate,

you can cut or saw oriented strand board than you are used to, because the cutting behavior of these materials is very similar to that of any type of OSB.

self-tapping screws;
anchor screws (dowel-nails);
rivets.

Self-tapping screws are well suited for fixing DSP to a wooden or metal base.

If you have only ordinary hardened self-tapping screws, then under them you need to drill a hole in the plate, as well as countersink the space for the cap. Without this, the cap will protrude above the surface of the plate, which will create great difficulties during finishing.

Without drilling, reinforced self-tapping screws can be screwed in, the hats of which are equipped with knives and cut a hole for themselves. The diameter of the hole for a conventional self-tapping screw is equal to 1.2 of the diameter of the self-tapping screw itself, and the diameter and depth of the hole for the cap exceed the size of the cap by 1.5 times.

It is undesirable to use ordinary screws for fixing, because they do not have the necessary strength, so with their help you will not be able to qualitatively pull the slab to the base.

After installing the screws, the holes for the caps must be sealed with putty, and after drying, process it with sandpaper.

Anchor screws are used when the panel needs to be attach to concrete or wood wall. To do this, put the plate in place and drill a hole for the plastic dowel. For fixing low density boards (300–500 kg/m3) it is advisable to use dowels with large caps for more effective fixation.

Such hats distribute the pressure created by the dowel-nail over a large area, so that the cement stone does not receive damage. In high-density slabs (over 700 kg / m 3), everything is done in the same way as when fixing with self-tapping screws.

Rivets use for fast fixing to steel or aluminum profiles where for some reason it is impossible to use self-tapping screws.

To do this, the sheet is put in place, then a hole is drilled, the diameter of which is 1.2 times the diameter of the rivet.

After that it is necessary using a special cutter, select the mounting hole under the rivet cap.

If this is not done, then the cap will protrude above the surface of the plate. It is also impossible to use a conventional drill instead of a cutter, because the cutter makes a hole with a flat bottom, to which the cap will be pressed tightly, and the drill makes a conical hole.

The cap will not be able to press evenly against such a hole, so over time the fastening will loosen, and the plate will begin to dangle. If there is no cutter, it is better to leave the rivet heads outside, they can be covered with a thin layer of plaster. It will be better than using a drill.

Finishing

The front surface of any cement-bonded particle board is very even, therefore, after sheathing the walls of the house with this material, it is enough to carry out only the finishing.

To do this, first carefully putty the seams, trying not to stain the plates much. Then, when the putty dries, joints and seams clean up with sandpaper.

After that, wallpaper is pasted, painted or any other finishing option is performed.

For wallpapering, use an adhesive that is suitable for the selected type of wallpaper and applicable to brick or concrete surfaces. For facing laying of ceramic tiles use only cement based adhesive, because it has the same thermal expansion as the DSP, so it will not crack under temperature changes.

During operation, the adhesive is dosed with a special notched trowel.

If you decide to paint the walls, then use any vapor-permeable paints and varnishes suitable for painting brick or concrete surfaces.

Output

Cement particle board is a modern finishing material, but it is most effective only when used correctly.

After reading the article, you learned:

What is DSP used for?
how this material is cut and drilled;
how the plates are attached to various surfaces;
is it possible to lay tiles on the DSP, and how to glue it;
is it possible to use this material in the steam room, including for installing the floor in the bath;
what types of finishes are applied to the walls of a frame house sheathed with DSP.

In contact with

Cement particle board (CSP) is a versatile building material suitable for both indoor and outdoor use. Moreover, in terms of the sum of its characteristics, it surpasses any wood-based sheet material (chipboard, OSB), because, in addition to high heat and sound insulating qualities, as well as enviable strength, the DSP board demonstrates acceptable fire resistance and the complete absence of warping or shrinkage. Thanks to this, DSP can be painted, plastered, finished with ceramics (tiles) or siding.

What are such plates made of - are additives needed

What are the specifications and sizes

Domestic enterprises have been producing the first DSP boards for floors and walls since the late 1980s. Now this composite building and finishing material is produced at six enterprises, adhering to the following size range:

Length - from 2.7 to 3.2 m. Moreover, the most popular plates are 3 meters long.
Width - exactly 1.25 m. This size is a kind of standard that determines the step of the crate when finishing the surfaces of the DSP.
Thickness - from 8 to 36 mm. Moreover, this parameter divides the range into 7 sizes, and the depth of the most popular sheets is 10, 16 and 20 mm.

The thickness and length of the sheet affect such a value as the weight of the DSP. Moreover, an 8-mm slab 2.7 meters long weighs the least - 36.45 kg, and a 36-mm slab 3.2 meters long - 194.4 kg will have the maximum weight.

Other technical characteristics typical for the DSP board are as follows:

Density - from 1.2 to 1.4 t / m 3. The difference in density depends on the level of humidity, which can be unstable (standards allow fluctuations within 3%).
Strength - bending 9-12 MPa, tensile - 0.4 MPa. As you can see, the plate reacts poorly to both bending and stretching. Another thing is longitudinal deformation. In this case, the resistance of the DSP is so great that it can be used to strengthen the load-bearing wall of the house.
Standard humidity is 9%. Moreover, after a daily stay in water, this indicator increases only to 16%, and the linear dimensions of the sheet change by 0.3% in length and 2% in thickness.
Vapor permeability - 0.03 mg / (m h Pa). Due to the porous structure, cement-bonded particle boards are classified as "breathable" materials, which, combined with the general environmental friendliness of the base, increases the attractiveness of this option in the eyes of builders of healthy dwellings.
Thermal conductivity coefficient - 0.26 W / (m K). Such a sheet cannot be compared with pure wood (0.15), but compared to brickwork (0.7), cement-bonded particle boards look very dignified, and compared to pure concrete (1.75), they are completely amazing.

However, no matter what technical characteristics the DSP plate demonstrates, the use of this material is associated with solving a narrow set of tasks that will be discussed below in the text.

Disadvantages of cement and chip slabs - what are they

After reviewing the characteristics, I would like to mention the disadvantages of the DSP. First of all, these include the significant weight of the sheet, which makes it difficult to transport the panel to the upper floors or roof. However, for the formation of a roofing cake, 10- or 16-mm sheets are usually used, the weight of which does not exceed 75-85 kilograms, which is quite acceptable for a roofing team of 3-4 people.

The second serious disadvantage of DSP is its low bending strength. Such plates are not suitable for the construction of arches and other architectural forms with curved lines. However, if necessary, the same OSB sheet can replace the cement particle board.

The practice of application in outdoor work - where it is useful

Due to the high frost resistance and acceptable moisture resistance that any cement-bonded particle board has, the use of this material in outdoor work will be justified even if thin, 8 mm sheets are used. DSP is used in the construction of ventilated facades. In this case, lighthouses are stuffed onto the wall of the building, on top of which sheets of cement and shavings are laid. Further finishing depends on the degree of grinding of the outer side of the panel. Unpolished material can be covered with plaster, not forgetting the reinforcing mesh. The sanded sheet is usually painted or left as is.

In addition, due to the high moisture resistance of DSP, the use of this material is also possible in the context of the base for the assembly of removable or fixed formwork. High stiffness, minimal moisture warpage and virtually water tightness make this material an ideal formwork for reusable or single use. Moreover, the sheets are easily processed, allowing you to assemble structures of even very complex configurations. And as a fixed formwork, DSP has an additional advantage - the sheet will work as a waterproofing agent, simultaneously insulating the base.

Sandwich panels based on sheets of chips and cement are also very popular. Such building materials allow you to assemble a house in a matter of months. In this case, the main advantage of DSP is the thickness of the sheet, which reaches 3.6 centimeters and allows you to increase the overall rigidity of the structure. Therefore, from sandwiches based on such sheets, it is possible to build houses of virtually any number of storeys. True, a sandwich panel made of a heavy-duty sheet with a thickness of 36 mm weighs more than 400 kilograms, which somewhat complicates the construction process.

DSP boards are used not only for floors or attic floors. In this case, the panels are used as cladding, they are stuffed onto the frame racks with a preliminary vapor barrier. Moreover, from the outside, the slab is first primed, raising the adhesion of the surface, and then painted or plastered, obtaining an outwardly attractive facade. Well, the internal layer of mineral wool located between the racks of the frame will be responsible for the thermal insulation in the frame house, so the heat resistance of the DSP in this case can be neglected.

Interior decoration and floor arrangement - for every taste

If you have a DSP board, the use of this material in interior work is limited only by your imagination. From the sheets, a high-quality rough sheathing for walls or a frame is obtained. Moreover, they can be covered with a layer of plaster or primer and wallpapered or tiled, so DSPs go to wet areas (bathrooms, showers, toilets, kitchens), and to ordinary rooms. Thick sheets can be used in the arrangement of interior partitions.

Moreover, 24- or 36-mm panels are used even without a frame. They are folded in 2 or 3 sheets, fixing to the ceiling and floor.

Such a move allows you to speed up the arrangement of the interior, and thanks to the wood base in the DSP, you can not only screw in self-tapping screws, but also hammer in nails, hanging pictures, mirrors, shelves or decor. DSP in the interior is valued for its high fire resistance. This material not only resists an open flame for 50 minutes, but also does not emit toxic combustion products. Therefore, such panels are classified as a low-combustible type of building materials G1 - under no circumstances will the DSP burn on its own.

However, the most common scope of such plates is interfloor, basement or attic floors. DSPs for floors or ceilings are more than willing to buy. This material can be used to insulate a concrete slab, strengthen the frame floor, and increase the moisture resistance of a wooden base. Installation of the floor (basement) based on DSP involves the following operations:

Waterproofing and soundproofing are laid on the supporting column.
A log (beam 5x8 centimeters) and cranial bars are laid on top. The placement step is 60 centimeters.
A plank flooring or a thin DSP slab is mounted on the bars - the use of thick slabs for a rough-type floor will be unjustified for practical reasons. After all, the draft floor holds only a heater.
A waterproofing membrane and a layer of insulation are laid on top of the flooring. Moreover, the thickness of this layer should be 2-3 centimeters less than the depth of the log - this space will go under the ventilation gap.
At the end, a DSP sheet is laid on the log and fixed to ordinary self-tapping screws with a countersunk head.

By acting in this way, it is possible to obtain a warm floor with excellent strength characteristics even with a 20 mm thick cement-bonded sheet. Panels with a thickness of 24-36 mm can be laid on sand-cement bedding or compacted clay, refusing to support posts. For residential buildings, this technology is not suitable, but for warehouses, a thick cement-bonded particle board, the technical characteristics of which indicate a readiness to withstand a large operational load, will come in handy.

The DSP plate, the technical characteristics of which will be presented in the article, is used quite often today. It is distinguished by outstanding qualities that have made the material common in private and professional construction.

Characteristics of the DSP plate

Due to the fact that the described material has excellent characteristics, it has found its wide distribution in various areas of construction. Cement particle board is composed of wood shavings, Portland cement, special additives, the latter of which are able to provide excellent protective qualities. During the production process, all of the listed components are combined, and then mixed until a homogeneous mass is obtained. Then the composition is pressed.

Products are manufactured in accordance with GOST, which strictly regulate the composition. Thus, among the components should be 65% Portland cement, 24% wood chips, 8.5% water, and 2.5% impurities. The density is ensured by the presence of Portland cement in the composition, the same component guarantees the durability of the material. The production of plates is carried out on special equipment in a factory, as evidenced by a quality certificate, as well as a product passport. The composition of the plates contains natural wood, which ensures the environmental friendliness of the material. This indicates that the stove is completely harmless to humans.

Positive features of the DSP

The DSP plate, the technical characteristics of which must be known before purchase, is of excellent quality, which makes it possible to use this material in professional construction. Technological processes for the manufacture of plates are based on the mineralization and bonding of all components, so it is possible to completely eliminate the appearance of a radioactive background, the release of steam, dirt or dust.

DSP slabs are actively used in the construction of strong and warm housing. Quite often this material is compared with others. The described plates are so strong that they win in this comparison. Their service life is much longer.
Additional advantages include excellent resistance to temperature extremes and frost, which meets the requirements for modern building materials.

The DSP plate, the technical characteristics of which are described in the article, has proven itself perfectly. These products perfectly cope with the influence of rodents, insects, as well as mold and fungus. The composition of the material does not contain phenol, asbestos, impurities and formaldehyde resins. These plates can be used for all types of finishes. The surface of the plates can be plastered, finished with plastic, painted, tiled, covered with various decorative materials, etc. It is easy to use this material, as it can be easily processed. It contains a large amount of chips, which makes the product look like natural wood, but these plates have high strength. DSPs can be used in the construction of partitions, which will have excellent soundproofing qualities. DSP walls will be able to provide sound absorption up to 30 dB.

Strength characteristics of DSP

DSP, whose technical characteristics differ from other alternative materials, have a high density. This is due to the fact that the chip pressing method is used in the production process. The inner layers of the product contain fibers that have a more impressive length. This guarantees the material excellent elasticity, smoothness, as well as high strength characteristics. The material has several layers, so it is able to deal with moisture. The special technology used in the production does not allow the product to delaminate. The slab will not break even if it is subjected to a mechanical force like bending. The material copes well with high loads, during operation it can be affected by a mechanical nature, which makes such plates so common and popular in construction.

DSP cost

DSP - a plate, the technical characteristics, the price of which should interest you if you plan to use this material in construction, may have different sizes. The most traditional dimensions can be called 1250x2700 mm. the cost of such a sheet will be equal to 675 rubles. This cost can be called very affordable, which makes such material so popular among analogues. Despite the fact that the cost of the plate is quite small, its quality remains excellent.

DSP dimensions

The DSP plate, the technical characteristics of which must be indicated in the quality certificate, must be examined by the consumer before purchase. It is important to consider the size range of these products. The plate can have a width of 1250 mm or 1200 mm. The latest standard is considered modern. But, despite this, slabs of different sizes are still being produced. The length can be equal to 2700 mm, while the thickness is equivalent to 8 mm. Such a product weighs 36 kg. If the thickness is increased to 10 mm, the weight will be 46 kg. Thickness of 12 mm increases the weight to 50 kg, and 16 mm to 74 kg. The plate thickness of 18 mm makes the mass equal to 81 kg.

With a slab length of 3200 mm, the thickness can be 8 mm, while the weight of the slab is 43 kg; with a thickness of 10 mm, the mass will be 54 kg, while a thickness of 12 mm gives a weight of 65 kg.

The standard size is 1200 mm. A plate with a length of 2700 mm can have a thickness of 8 mm and a weight of 35 kg. A plate thickness of 10 mm gives a mass of 44 kg. Among other things, the buyer can purchase a plate that has been made to certain dimensions. The length of the slab can be 3600 mm or 3000 mm. You should not look for products on sale, the edges of which have a semicircular shape, since such plates are not available. Also, products whose edges are thinner are not produced in the factory. After the plate is purchased, it will not need to be treated with an antiseptic, since the products are exposed to antiseptic effects at the factory.

Scope of DSP

DSP slab, the technical characteristics of which must be studied before making a purchase, is used today in housing construction. Products are able to provide internal protection from the cold. This material can be used when cladding walls made of concrete. Products are used in low-rise construction, as well as in the construction of special-purpose buildings. DSP is excellent for rooms whose conditions are characterized by a high level of humidity. After the plate is installed, its surface does not have to be treated. It will be enough just to cover the surface with a primer or a composition that has water-repellent characteristics. Buildings in which DSP is used are capable of undergoing serious operational loads.

Additional scope of products

The DSP slab, the technical characteristics, the application of which can be found in this article, is also used for fixed-type formwork equipment, which allows achieving excellent results. At the same time, some positive features can be distinguished, among them: reducing the time for construction work, reducing the amount of construction costs, as well as ensuring the reliability and strength of the future structure. The DSP plate, the technical characteristics, the use of which made the products popular, is also used today in the manufacture of window sills. At the same time, the latter are obtained not only durable, but also quite inexpensive compared to analogues. You should not assume that due to the insignificant cost of the DSP, the window sill will have a very unsightly and unpresentable appearance. Such products have excellent decorative qualities and look like expensive window sills made of noble materials.
