Cement sandy solution consumption M3. How much will weigh the cube solution? Features of making a masonry solution

In order to prepare concrete, you will need three components: cement, sand and crushed stone. Compliance with the proportions of the main components affects the quality of the finished product. Consider more detailed what cement consumption per 1 cubic solution.

How much cement is needed on cube concrete

Depending on the purpose of concrete, it is made with definite strength. For example, the M100 brand is used to fill the base of roads and creating borders, M150 - the construction of small buildings, M200 - for filling the foundations.

If there is too little cement in the concrete, it is not able to keep a binder and filler, and such a material will quickly collapse under the influence of external factors. Conversely, significantly exceeding the hardener's volumes, will lead to cracking of the final product.

How many cement bags need 1 cube concrete

Building materials are better to purchase in bags, packaged 50 kg - it is easier to calculate the proportions of the components. For example, for the manufacture of concrete mixture under the foundation, the recommended ratio of cement, sand, rubble and water - 1:3:5:0.5 . This means that on 1 bucket of cement you need to take 3 sand buckets, 5 buckets of rubble (gravel) and half-water.

To calculate cement consumption per 1 m2 screed, use the calculator. To begin with, the required solution should be calculated: multiply the thickness to the surface area. So, for the manufacture of a screed of 30 mm thick for room 15 m2, you will need: 15x0.03 \u003d 0.45 m3 of concrete.

If the floor is originally a curve, you need to take an average value as a height. For example, to calculate the consumption of a concrete solution on a screed, in which one corner will be 1 cm thick, and in the other - 5 cm, you should take a quantity thickness of 3 cm.

Cement consumption per 1 m2 brick masonry is also calculated based on the required amount of the finished solution. An exemplary consumption of cement masonry mixture on brickwork is calculated for a cubic meter of future masonry. The volume of masonry is easy to calculate, knowing its area and the thickness of the bricks.

Approximate consumption can be found from the table:

No cement mortar is impossible no construction. The correctly composed cement-sandy mixture is the key to the fact that the object will be durable and just just time. In the preparation and preparation of the cement mortar there are no little things, even minor details are important here.

Features

In modern construction, a cement mixture is most often consuming, which is compiled in certain proportions with sand.

There are several options for cement mixtures that are in demand, namely:

• to make a screed takes a mixture in the ratio of cement to water 1: 3, additives and fiber opens are also often added;
• for masonry, a solution of 1: 4 is used, the grade cement is not lower than M200;
• for plastering, a mixture is usually used 1: 1: 5.5: 0.4 (cement, lime quenched, sand, clay) is a M50 solution.

Cement concentration in different mixtures per 1 cubic solution can vary significantly. This fact depends on the types of work and the intensity of mechanical loads that are experiencing various fragments of the structure. Beginner builders often do not give due value to the proportions of materials in cement mixtures, thinking that this question is insignificant. This is a deep misconception, because correctly compiled shares on m³ is the main key to the fact that the object will be durable and durable. It is recommended to take advantage of the composition of the cement mortar.

Consumption rate

The following tools will be required to work with cement mortar:

• concrete mixer;
• device for weighing a bulk substance;

• buckets in which the mixture hangs;
• calculator;
• the table, which indicates 1M² the coefficients of sand density, gravel, cement, lime mixture.

Usually solution compositions include one binder.This solution is called simple. But there are mixed solutions in which several plasticizers can be added. If the solution is only with the addition of sand, then it turns out quite dense and heavy by weight. It ranges from 1680 to 2100 kg per cubic meter volume, in lighter solutions, a similar indicator is noticeably less - up to 1650 kg per cubic meter.

What does it depend on?

The mechanical strength of the cement mortar can be such graduations as 2, 4, 10 and 25. Guided by tables and standards, it is possible to reduce the consumption of such a valuable material as cement without prejudice to the strength of the structure. Usually for construction works, for example, a grade 400 cement is used for a screed. The most common solutions are M25 and M50. To prepare M25, the sand ratio is required in relation to cement 5: 1. To make the M50 substance, the proportion of 4: 1. It will dry out such a composition for three days with a layer thickness of 1 cm. Sometimes arbolit or PVA glue is added, then the coating is obtained yet Strong.

Attention should be paid to the consumption of cement when you need to prepare one cube concrete.

To important indicators for which the quality of the solution is determined:

• density;
• viscosity;
• grappling time.

In order for the mixture to be high-quality, it should be well stirred. It is necessary to follow the proportions of sand and cement consumption. In the M600 brand solution, the presence of cement is required in a ratio of 1: 3. If the M400 brand cement is present, the ratio is obtained 1: 2.

It should be borne in mind that when calculating the amount of cement to obtain the required volume should be multiplied by the coefficient of 1.35, because there is an addition of water and various additives. One cubic meter of solution will require about 68 cement bags by weight of 50 kg. The most popular cement marks for the construction of the foundation are M200, M250 and M300. The foundation requires a solution in which the optimal compression ratio will be present.

If the brand cement M100, then the list will attend the following density:

• M100 -175 kg / m³;
• M150 - 205 kg / m³;
• M200 - 245 kg / m³;
• M250 - 310 kg / m³.

For plastering for one square meter, with a thickness of layer 1 cm, about 2 mm cement will be required. With such a thickness of the layer, the material works well, not deforming and not crack.

To put the slag blocks will need the following relationships:

• M150 - 220 kg / m³;
• M200 - 180 kg / m³;
• M300 - 125 kg / m³;
• M400 - 95 kg / m³.

When finishing the facade, special pigments and semicircles are often used, as well as salt, soap solution, which improve the quality of materials. When preparing the mixture, the dry substance is first carefully stirled, only then the liquid is added. The mixture is usually prepared in a small amount, because it has the ability to quickly capture. To make the M150 and M200 brands, the proportions of cement and sand 1: 4. If a solution of the M400 brand is needed, then such a composition has a proportion of 1: 3.

Concrete is in the greatest demand in construction. Its main components are crushed stone, water, sand, cement. It is important to initially represent for what purposes will be used concrete. Its consumption averages about 245-325 kg. It all depends on the cement brand, in which ratio and proportions are preparing a mixture.

How to calculate?

The cement of higher grades is used, as a rule, in industry to create durable structures. In everyday life and civil engineering, their use is found in rare cases.

Cement brand 500 is often used to create such supporting structures as piles, overlap and fastening beams. Such cement shows well at low temperatures, has high anti-corrosion indicators. It is also often used in the construction of various overlaps, beams and stoves. The characteristics of this cement also include good frost resistance and water resistance, as well as it has an excellent anti-corrosion capacity and is therefore often used during emergency operations.

It is recommended to follow the recommendations for proportions. The presence of cement directly affects the plasticity of concrete and its other indicators. Most often consume the following ratios: cement (1 kg), sand (3 kg) and crushed stone (5 kg). Sometimes a little glass is also added, which is why it becomes even stronger. With this ratio, the concrete mixture will be very durable. Any deviations from prescribed proportions lead to poor-quality composition. The brand used in obtaining this material should be more on average twice the brand of the obtained concrete.

For convenience, the work usually use bags with cement 50 kg. As an example, to get concrete M200, you should use four cement bags. For masonry, a solution based on lime is often used, which is characterized by good plasticity indicators.

If you want to make plaster facades, then such mixtures are optimal for such work. For carrier walls, a higher brand cement is used, this will provide additional strength of the object. The M500 binding material is used in the ratio of 1: 4, if the cement brand M400, then the ratio, respectively, 1: 3. When the mixture is done with your own hands, it is usually used by cement that has a brand twice as much brand of the product obtained. For example, if you need to get a mixture of M100 brand, then the cement must have a M200 brand.

Calculation of the area of \u200b\u200bthe wall

In one cubic meter there are 482 bricks in size 242x120x64 mm. The consumption of brick on the laying depends on the thickness of the walls. For Russian realities, external walls are optimally suitable for two bricks. A single brick has dimensions of 252x120x65 mm, one-time - 252x120x87 mm, double - 252x120x138 mm. Based on these indicators, it is easy to calculate how much bricks will be required by 1 m².

If we talk about the consumption of cement on the masonry, then this indicator depends largely on the thickness of the seam. This parameter is usually 15 mm. It should also be borne in mind that for silicate bricks it is necessary much more solution than for facing. The solution is most outlieved on the hollow brick, in this case the cement-sandy mixture is made in a dry form 1: 4. A little water is added to a small container and a cement-sand substance is added, stirring it to a semi-liquid state.

The main solution is spent on the laying of hollow bricks.For such a masonry, it takes a seam of at least 0.2 cubic meters of solution, given that the width of the brick is 12 cm. If you make a masonry in one brick, then the solution will be 0.23 m³, 0.16 m³ is required at one-hour stone. The number of consumable liquid mortar should also be taken into account.

Observing the different proportions of the preparation of a sandy-cement solution, you can get at the output of the base for the concrete of any brand. Therefore, in this article we will talk about how to produce solutions for fill, masonry and other needs, considered a variety of proportions, as well as mixing component mixing technologies.

Cement-sand mixtures and concrete components

Such building materials consist of three mandatory components:

• the binder - the cement acts in this role;
• filler - in this capacity uses sand and mineral component (crushed stone);
• water - she launches the reaction of the formation of cement stone, thanks to which viscous building materials acquires strength.

A typical binder is a portland cement grades 400 and 500, less often than 300 or 600. And the greater the brand number, the stronger the casting or masonry. In addition, the strength characteristics also affect the proportions that determine the ratio of the binder and filler. Typical fillers are sand and crushed stone. At the same time, the thinner of the first component (sand), the greater the percentage of the content of the second component of the filler (rubble). Therefore, medium and large sand takes through the sieve with a cell diameter of 1.2 to 5 millimeters.

The sandy part of the solution should not contain clay. Upon receipt of commercial and fatty solutions, the soils are separated into the water jet using the washing procedure, since even a small amount of clay in the filler significantly reduces all the strength characteristics of concrete. Crushed stone in solutions is used either gravel or granite. The size of the rubble fraction can be set from 4-5 to 7 centimeters. However, the grain should not be more than 2/3 of the minimum distance between the reinforcement rods. Therefore, in most cases, rubble is 40-50 millimeters on the commodity solutions.

Water into a commodity solution is supplied in proportion from 1: 3 to 1: 2 from the mass of cement. The water-cement ratio is 0.3 and 0.5 ensures confident hydration and high plasticity, and then the hardness of the resulting mixture. And the fluid itself can be both drinking and technical, but necessarily clean. In addition, a number of additives that improve the plasticity of the medium and the moisture resistance of the resulting casting are added to heavy and fatty solutions. There are also reinforcing fiber additives that increase the strength characteristics.

Household solution 1: 4 or 1: 5

Before breeding cement, most home-grown builders and finishers look at its brand. And if we have the 400th composition before us, then four parts of the filler take on one part of the binder, adhering to the ratio of 1: 4. Accordingly, the 5: 5 ratio is used for the 500th brand. These solutions have become a kind of household classic used and when laying bricks, and when pouring concrete bases, tiles, poles. At the same time, the water and rubble are added "on the eyes", and the components are measured by no kilograms, but buckets.

As a result, it turns out a moderately durable and frost-resistant solution, bribing the simplicity of manufacture and low cost. However, the plates and plaster are very soon obtained in this way, not even from the load, but from frost. After all, connecting cement with sand, you need to focus not only on the mutual volumes of these components, but also on the mass part of water, rubble and various additives. Therefore, further in the text we present industrial recipes, determining the accurate consumption of cement and sand on 1m 3 standard solution used for masonry, finishing and fill.

Solution for brick or block masonry

To connect separate blocks or bricks, we need a solution based on only a bulk filler. No rubble here should be. In this case, for loaded walls, the commodity composition will be determined by the 1: 3 ratio, and for unloaded - 1: 4. Cement consumption per cube solution in this case can be calculated in liters, and kilograms. And, according to proportions, for a loaded wall, we have it that it is necessary to add 750 liters of the filler to 250 liters of the binder (1 m 3 \u003d 1000 L). And since the liter contains 1.4 kg of cement, the mass of the knitting part will be 350 kilograms.

Part of the sand is calculated by the formula 1 liter \u003d 1.2 kilograms and equals 900 kilos. Waters in this case require no more than 175 liters (350 × 0.5).

For an unloaded wall 1M 3, it is divided into a 200 liter knitting part and a 800-liter residue on the filler. Kilograms turn out 280 and 960, and the water here needs no more than 140 liters. According to the formulation, the first option is similar to the variety of concrete M300, but does not have its strength due to the lack of rubble in the structure. The second option is like M200, at least, such a number of binder is present at the concrete of this particular brand. However, the real M300 (B22,5) and M200 (B15) used in the pouring of reinforced concrete products (Ruby) are prepared according to completely different technologies.

Concretes for filling reinforced concrete products

In this case, we will need brands with high strength characteristics B22.5 (M300), B25 (M350) and B30 (M400), which are able to withstand the load from 22.5 to 30 MPa. To produce such solutions in the amount of one meter cubic, it is necessary to follow this formulation:

• For M300: 380 Kilo cement mixed with ton sand and 830 kg of rubble, adding 175 liters of fluid. Stirring is in the concrete mixer, and a plasticizer is used as a additive (at least 6.2 kilo per cubic meter).
• For M350: 420 kilograms of cement, mix with ton sand and 795 kg of mineral filler. In this case, solving how much water is needed, oriented on a water-cement ratio of 0.4 and poured 175 liters of liquid into the concrete mixer, adding 6.9-7 kg of plasticizers.
• For M400: 470 kilo cement, sand tones, 0.76 tons of rubble and 175 liters of water are poured into the concrete mixer and mix with the addition of 7.7 kilo plasticizer.

Using M300, you can pour any domestic construction - from the path in the courtyard to the foundation for low-rise cottages. In addition, this variety goes to elements of staircases and cast panels. But to achieve, you need strength to know how much and what to add to the concrete mixer, and follow the above recipe without deviations.

M350 cast foundations of factory workshops and large supermarkets. This variety is also on the panel and overlap for multi-storey objects. If you are using M350 in everyday life - how much such casting is just like, you will not see. She will live longer than one generation of users. Mark M400 goes to filling the spans and bulls for bridges, the manufacture of monolithic banking storage facilities, the arrangement of foundations for special machines and presses. Prepare such a solution, you will receive a concrete of very high strength, but it is unreasonable to use it in everyday life due to the solid cost of components.

Cement-based finishing solutions

For the draft finish of the basement overlaps and the arrangement of leveling screeds, it is better to use concrete M200 brand. For its preparation, based on the exit in the volume of one cubic meter, you will need 260 kilo viscous substances (cement), 1.08 tons of sand, 900 kg of rubble and 155 liters of water. You can make it manually (in a trough) or in a concrete mixer.

It is better to use compounds with cement content in 1 cube of the finished mixture as the plaster solutions, like the option for laying bricks or blocks. Recall its composition: 280 kilo cement, 960 kg of sand and 140 liters of water. For sealing small slots, chips and holes, you can use only the binder, but before breeding cement (without sand), take into account the high fragility of the concealed mass. That is, there is no longer any such solution on the corners. And try to use no more liter of water for five kilos cement.

Not only the deadline for the end of work depends on the proper planning of the expenditure of construction materials, but also to greater the quality of the design. The most complicated in the calculations is accurate compliance with technological standards. In addition, knowing exact number of materials, you can significantly reduce the cost of construction, since the amount of waste will be minimized.

Why cure proportions

If, in the calculations applied to the materials measured in linear units, it is rather difficult to be mistaken, then in the case of dry mixtures and their error components are quite common. It will not be difficult to calculate the number of bricks for the construction of the wall, knowing its size, but for calculating the number of components for the cube of the masonry solution, difficulties may arise. In a word, the consumption of cement on 1 cubic solution for certain purposes we will consider today.

To obtain a high-quality cement mortar for certain purposes, it is necessary to strictly observe the proportions not only cement, but also all other components. Crushed stone, sand, like cement, must also be added in a certain proportion. The fact is that when the consistency of sand or rubble is exceeded, the consequences for the design as a whole can be the most disappointing.

Consumption of cement and sand on the cube solution

If there is too much rubble to the solution, the cavities will remain between fractions, in which the cement did not hit, and, respectively, the product or design element will not be monolithic and will not correspond to the calculated load and other characteristics. Hence the low life, premature repair costs or at all on the replacement of the element failed, if it seems possible.

The same story may occur when the proportion of sand exceeds the norm. In this case, we involuntarily increase the consumption of cement on the cube of a solution for a screed, but do not get the necessary strength in any case. Hence the golden rule of cement proportions is coming:

Waters need to be added smoothly as much as required technical conditions or more nor less. The main factor affecting the quality and suitability of the concrete mix for certain conditions is the brand and the number of cement. In addition, we provide several different tables with exemplary proportions for the preparation of concrete mixes of a completely different destination.

Golden proportion of concrete mix

In principle, the norms of consumption of cement fit into clear mathematical calculations, but in order not to overload the rough mental work of builders, these tables are created. Each of them corresponds to the principles of proportional compliance, which we led above - 1/3/5. Accordingly, to obtain a hypothetical unit of the finished solution, it is necessary to mix nine equal parts of all components.

In order not to delve into the arithmetic course for the third class of the secondary school, let's say that it is necessary to have 333 kg of middle cement to obtain a medium cubometer of the solution. The entire difference in proportions is dictated by the peculiarities of a technological process in which the mixture is used - on the cube of the solution for plaster and on the same amount of the mixture for a solid screed, naturally, the amount of cement will be slightly different, which is indicated in the tables.

The value of the cement brand

At the same time, it is also necessary to take into account the brand of cement. It does not need to recount every time a re-proportion if the purpose of the cement mortar or the cement brand has changed. Each of the solutions is marked according to the cement brand. So, if the concrete of the brand 300 is required for the foundation device, and there are only the cement M400 grades, it is enough to refer to the tables that will give the necessary amendment to the cement consumption of the brand that is supposed to be used.

For example, to get the brand 100 concrete cube, you need to spend:

• 390 kg of cement brand 300;
• 300 kg M400;
• approximately 250 kg of cement brand 500.

Features of making a masonry solution

But it is still halfbes. For the preparation of concrete, for example, for screeds or fill the foundation, no need to take into account the properties of materials that are directly in contact with the solution. Masonry mixes are much more complex in preparation and calculations, and all because each of the wall materials has its own characteristics.

As a rule, on the norms of consumption of materials for a masonry solution, make a correction based on the structure, porosity, the ability to absorb moisture, of a particular building material. Of course, the golden proportion for brickwork will be true, but an experienced bricklayer will always make changes in proportion, just looking at the quality of the brick or wall block.

Thus, the calculation of the amount of materials for the preparation of the solution is based on proven data practices reduced to the table, but taking into account the amendments that provide for the features of a particular material. Successful kneading!

Answer:The theoretical determination of the weight of the cube of the construction solution is complicated by the fact that the solutions can have several components (complex solutions), the different ratio of these components, as well as different types of sand on the density of grains.

The weight of 1 cube of the solution directly depends not only on its components, but also from humidity. According to the GOST for medium density, the solutions are divided into light and heavy. Light solutions include building solutions with a volume weight of less than 1500 kg / m 3. To severe solutions, respectively, solutions with a volume weight of more than 1500 kg / m 3. Heavy solutions are prepared on the aggregate weights of more than 1200 kg / m 3 and with hardening they have greater strength and density. Light solution due to the presence of a set of air pores have less thermal conductivity. The weight of the cube of the solution depends the same on the size of the grains of the aggregate, as well as from the particle size distribution - the ratio of grains of aggregate. The largest volumetric weight of the aggregate and, as a result, the solution will be in the event that a certain ratio between the amount of grains of various size is observed. For example, 1 m 3 of sand with grains with a diameter of 1 mm weighs about 1400 kg, and from a mixture of grains 0.15-5 mm weighs 1600-1700 kg.
And if we consider that sand is not the only type of aggregate, we can conclude that the weight of the cubic meter of the complex solution can only be installed experimentally, by weighing vehicles or approximately using tables:
