Sand consumption per cubic meter (1 m3) of solution. How much cement do you need to purchase to prepare different grades of mortar? Cement consumption 1 m3

Cement is a building material whose importance is rivaled by few other things. It is used in the production of dry mixtures, building materials, pouring the foundation. But when we take it, do we know its consumption? But this is very important.

Peculiarities

First, let's look at the subtleties and unusual features of the solution and its components. Let's start with the main component - cement. In its primary form, this building material is represented by astringent mineral powder. When mixed with water, it becomes viscous and dark gray in color. Another obvious feature of cement is that it hardens quickly in air. The powder itself is obtained by grinding clinker and adding gypsum and various types of minerals to it.

To obtain a high-quality solution, it is necessary to observe not only the proportions of cement, but also all other materials, otherwise the future of a particular structure is called into question.

Before we begin to analyze the actual cement consumption per 1 cubic meter of solution, we should understand the types and brands of mixtures that each of us may encounter.

Types and brands of mixtures

Information on concrete grades and their scope of application is presented in the following table:

Concrete marking	Usage
	Material used for preparatory activities.
	Has sufficient strength parameters suitable for solving various kinds construction tasks.
	An option more suitable for pouring the base.
	Concrete of a wide range, which is characterized by a high strength index.
	Material with average performance. It is mainly used for the construction of hydraulic structures.
	According to the specifications, this material is used for the construction of skyscrapers, bridges, and underground structures.
Arbolit (M5-M100)	In this table it has the lowest strength indicators. Wood concrete can be used to make elements for low-rise, industrial and agricultural buildings.

But if it is necessary to give the solution more plasticity and elasticity, then PVA glue should be added to it. It is an aqueous emulsion of vinyl acetate polymer with special additives that contribute to such unusual qualities of the mixture.

PGS

Among huge amount materials on the construction market, one of the highest places is occupied by gravel-sand mixture (PGS). Indeed, in terms of production volumes and areas of application, it surpasses all other rocks. From of this material you can prepare concrete High Quality.

Composition of ASG

If you ask any person about its composition, he will answer you without much thought that it consists of sand and gravel. And he will turn out to be absolutely right. In addition to the main components mentioned above, the mixture also includes clay lumps (no more than 1%) and dust inclusions (no more than 5%).

Types of PGS

1. Marine view. The composition is homogeneous and has practically no foreign inclusions. Features a rounded shape. Contains almost no clay particles.
2. Mountain-ravine view. Characterized by the acute angular shape of the particles. Contains remains of parent rock.
3. Lake-river view. It has quite a lot of similarities with the marine species, but if we highlight the features, then in the lake-river species there are much more foreign residues and organic matter, such as silt and the like.

Scope of application of ASG

The scope of application of this mixture is quite high. It can be used for leveling construction site, when filling pits and trenches or even when laying communications.

If you want to get fairly high strength and which will not shrink over time, even under heavy load, then you should pay attention to the ratio of the main components: 30% gravel and 70% sand.

Consumption rate

First of all, you need to know how the concrete will be used and for what. If you need to obtain a solution of high quality and strength, then you should adhere to a clear technology. Also, the consumption per 1 m3 largely depends on the brand of concrete itself. It is for this reason that you should know for what purposes it will be used.

The process of preparing the solution can be made much simpler by buying cement in bags that come in 50 kg bags. This way you will make the calculation easier for yourself. The construction of brick structures is of greatest importance, so let’s look at some of the subtleties associated with this masonry.

Methods for preparing the mixture

The quality of the masonry is determined not only by the characteristics of the brick that is used, but also by the method of preparing the mixture itself. Let's look at the most popular and effective ways preparations cement mortar:

1. The most popular recipe is a solution to which you add sand and cement. It is quite durable, but when preparing it, you must strictly observe the proportions: even the slightest deviation from the norm can result in the formation of a large number of cracks.
2. Solution lime based(lime). Its advantage lies in its high ductility. The disadvantages are that it is not waterproof, so if you intend to use it on the outside of a structure, be prepared for it to simply wash away in the rain.
3. The next type is called mixed. And this is exactly the case when they took all the best and combined them together. It has excellent strength combined with good ductility.
4. Solution with cement in the base and additives in the form of plasticizers. This composition is characterized by improved qualities of the previous type, that is, a mixed solution. And thanks to the presence of plasticizers, working with it is much more convenient and faster.

But on what factors does the cement consumption per 1 m2 of brickwork depend? Below are the most important of them:

1. Worker's choice. This factor plays one of the critical roles. After all, how much of the mortar will be used for its intended purpose, how much will go to waste, and how smoothly the brick will be laid depends on his level of qualifications.
2. Brick. He plays an important role. For example, for hollow brick it will take much more material than for a full-bodied one.
3. And, of course, this is the thickness of the seam. This value should be between 10 and 12 mm.

Let's take a closer look at the consumption of cement composition depending on the type of brick used. So, when applying the mixture to a solid brick base, this parameter will have the following values:

• if the masonry is carried out in half a brick (width -12 cm), then the consumption will be 0.19 m3;
• when installed in one brick, 0.22 m3 of mortar will be required;
• with a wall width of 38 cm, approximately 0.234 m3 of composition will be needed for high-quality application.

In the case of solid brick, the consumption parameters will be different:

• when laying half a brick, 0.160 m3 will be consumed cement mixture;
• if application is carried out on a base of one stone, 0.200 m3 of solution will be required;
• when laying one and a half bricks, the consumption will increase to 0.216 m3.

Now let's move on directly to the cooking standards. And for this purpose, below is a table indicating the brand and ratio of all components included.

When the work itself begins, you must first deal with dry materials, and only then start adding liquid ones (water and other fillers). This is done to ensure that the solution is homogeneous and does not contain lumps. Also, to avoid an unfavorable result, you need to mix everything thoroughly.

Don't do too much a large number of cement mortar. After all, do not forget that the mixture hardens very quickly in air. Of course, if you want to save your time and effort, you can go to the store and buy everything ready-made, but here it all depends on whether you can afford it.

And now a small digression for those who work with solutions in cold seasons. Many people are faced with the fact that when all the standards have been met and fulfilled preparatory work, the structure of the composition is still broken. The thing is that the water used for kneading froze and destroyed the entire structure. Therefore, to avoid such adverse effects, salt or other antifreeze additives are added to the solution.

We have sorted out all the aspects related to the work, but there is still a lot left useful tips, which can make your work not only simpler, but also of high quality, and maybe even not too financially expensive.

The most important thing is to find out whether the solution is prepared well. To do this, you can resort to a simple method: you need to write several letters or numbers on the laid surface. If they do not float or, conversely, do not crumble inside, then this means that the solution is prepared correctly and can be applied to the surface.

To determine how much sand and cement is needed per 1 cubic meter of mortar, it is important to know its purpose. To prepare masonry, plaster, foundation and other types of mixtures, different ratios of dry materials are used. The consumption of sand and cement per 1 m3 of mortar varies for each type of work, and often other dry or liquid formulations, increasing moisture resistance, strength, changing the rate of hardening of the mixture, etc.

What determines cement consumption for different solutions?

The preparation of cement mortar, the proportions of which may differ, requires strict adherence to technology and the correct determination of the ratio of components. For the use of concrete of different grades it is used different quantity cement and sand. Remembering the proportions of cement and sand is not enough for high-quality construction; it is better to understand the principle.

Requires strict adherence to the technology for preparing cement mortar

Main factors influencing consumption:

• the amount of fillers in the mixture. The greater the proportion of crushed stone and sand, the higher the cement consumption per 1 m3 of solution. Cement is the binder of the components, which is responsible for holding all the fillers together. The ratio of bulk mixtures determines the amount of cement;
• brand of cement. As the grade increases, the strength of the final structure increases. It is worth remembering that the grade of the final mixture is significantly lower than dry cement, since sand is added to the composition, and gravel or slag can also be added;
• brand of solution. The cement-sand mortar is also divided by grade. For all types of work, GOST has recommended brands. After determining the desired brand construction mixture, you can choose the right brand of cement. For example, to obtain an M100 mixture from M500 cement, you will need to mix 1 part Portland cement, 5.8 parts sand and 8.1 parts crushed stone. If final goal– M450 mortar, you will need a proportion of M500 cement (C:P:SH) 1:1.4:2.9;

The density of cement plays a secondary role here, since it directly depends on the brand of cement, but it is necessary to know it during the calculation process.

Conclusion: how much cement is required per 1 m3 of mortar depends on the required strength of the mortar and the brand of the initial mixture.

The density of cement directly depends on the brand of cement

Types and brands of mixtures

The introduction of the concept of “cement grade” helps to calculate the cement consumption per cube of mortar if the input parameters are known. To prepare a solution with the same construction characteristics from different brands of cement mixture, you will need different proportions fillers. Cement is produced in production, starting from grade M100, but due to high strength practically no material is used in the construction.

The most popular cements are M400 and M500, but some other types have also become widespread. The choice of mixture depends on the scope of application of the material.

The main areas of use of cement grade:

• M300 cement is used in installation construction, as well as during the manufacture of monolithic structures;
• M400 cement is successfully used in monolithic construction and during the preparation of reinforced concrete;
• M500 cement is actively used in the construction of buildings or slabs that must be resistant to moisture or located in water. Areas of application of this concrete mixture are quite wide: the creation of sidewalks, the construction of asbestos-cement structures, the formation of large concrete masses and all kinds of foundations;

M400 and M500 cements are the most popular

• M600 cement is used to create prefabricated structures and foundations that are subject to high loads;
• M700 is a suitable grade of cement for the construction of highly loaded and stressed structures.

Material consumption rates per cubic meter of different solutions

Today there are 4 main areas of use of concrete: foundation, masonry, screed and plaster. In each case, the building mixture is subject to special requirements, which makes the choice of cement and its consumption different. The greatest consumption of cement per cube of concrete occurs when it is necessary to make masonry or plaster. The consumption of materials per 1 m3 of foundation mortar is slightly lower due to the use of a large filler fraction: slag, crushed stone or gravel.

GOST has records of cement consumption rates per 1m3 of mortar, taking into account the purpose of the mortar. Designation of concrete per cubic meter. meters is a generally accepted system of measurement.

Cement consumption rates per 1m3 of solution

Consumption standards per 1 m3 using M500 cement:

• on M100 – 170 kg;
• on M150 – 200 kg;
• on M200 – 240 kg;
• on M250 - 300 kg;
• on M300 – 350 kg;
• on M400 – 400 kg;
• on M500 – 450 kg.

Consumption rates for cement and sand per cube of foundation mortar

Calculation of cement for foundation calculator is the simplest way understand how much material is required and the number of necessary components. Concrete calculations can be done with high accuracy and manually.

To determine how much cement is needed per 1 m3 of solution, we recommend following simple instructions:

Cement consumption rates for foundations

1. We determine the appropriate brand of cement mortar. Usually, when creating a foundation, it is advisable to use a solution of M100-M300. For low-level buildings, M100 is sufficient, if you plan to build several floors - M150, and M200 and higher are used in construction multi-storey buildings and any structures that are subject to increased strength requirements. If the foundation is built under wooden building, an M50 solution is sufficient.
2. We select the brand of cement. For standard tasks, M300-M400 is suitable in the proportion of cement to sand 1 to 3. When using cement M500 - 1 to 5.

How many kg of cement in 1 m3 of solution:

• in M50 when using M400 – 380 kg;
• in M100 when preparing concrete from M300 cement – ​​214 kg;
• in M200 with cement M400 – 286 kg;
• in M300 at M500 – 382 kg.

The data is presented if the cube contains 2-4 parts of sand and 3 parts of crushed stone.

Consumption rates of cement and sand per cube of masonry mortar

To prepare cement mortar for wall construction, a proportion of 1 to 4 is most often used. Thus, the cement consumption per cubic meter will be 0.25 m3 or 325 kg, and the sand consumption per 1 m3 of mortar will be 0.75 m3 or 1200 kg.

Cement consumption rates for masonry

Table 1: Mortar consumption for walls of different thicknesses

To calculate how many bags of cement are needed, just multiply 325 kg by the consumption per cubic meter, for example, walls of one brick - 0.221. You will get 72 kg of cement for laying 1 m3 of wall, provided that the composition does not contain other components (lime, clay, etc.).

Consumption rates of cement and sand per cube of screed mortar

Cement consumption per 1 cubic meter of solution is calculated according to similar rules as in previous mixtures. The recommended mixing ratio is 1 to 3. Difficulties in calculations often appear at the stage of determining the volume of the solution, so let’s consider clear example. It is necessary to fill a surface of 3x4 m or 12 m2. The layer thickness will be 30 mm.

Cement consumption rates for screed

Calculation of cement for screed from the example:

1. We are counting required volume solution: 12 m2 * 0.03 m = 0.36 m3.
2. We determine the brand of cement, M200 solution is often used, and we use it as an example. We will cook from M500, and according to the standards, the consumption will be 410 kg.
3. We calculate the required number of bags of cement: 410 kg * 0.36 m3 = 148 kg - this is 6 small or 3 standard bags of 50 kg each.
4. We determine the cost of sand. To do this we multiply specific gravity 1 m3 of sand for the required amount ready mixture: 1600 kg/m3 * 0.36 m3 = 576 kg, and since the share of sand in the total solution is 75%, we also multiply by 0.75 - 432 kg of sand. Sand consumption per 1 cubic meter of solution is approximately 1200 kg/m3.

Consumption rates of cement and sand per cube of plaster mortar

Cement consumption per 1 m2 of plaster greatly depends on the quality of the wall covering, required thickness layer and number of large holes. Again, for clarity, we will give an example of a calculation, remembering that a mixture of 1 to 4 is usually used. Input parameters: it is necessary to cover 60 m2 of walls with plaster 2.5 cm thick.

Calculations of cement and sand consumption per 1 m3:

1. Amount of materials in cubes. For 1 m2 you will need 1 * 0.025 = 0.025 m3 of solution, where a fifth is cement and the rest is sand. Using elementary mathematics, we determine that 0.02 m3 of sand and 0.005 m3 of cement will be required.
2. For the entire area of ​​the wall you will need: 0.02 * 60 = 1.2 m3 of sand and 0.005 * 60 = 0.3 m3 of cement.
3. The specific density of cement is on average 1400 kg/m3 (fresh 1100-1200 kg/m3, and compacted 1500-1600 kg/m3). We determine the cement consumption: 0.3 * 1400 = 350 kg.
4. Required weight of sand: 1.2 * 1600 = 1920 kg, we remind you that 1600 kg/m3 is the specific gravity of sand.

All calculations are simple; it is only important to choose the right brand of the initial mixture and the desired brand of output solution. Everything else can be easily calculated in a few mathematical steps.

Answer: The theoretical determination of the weight of a cube of building mortar is complicated by the fact that solutions can have several components (complex solutions), different ratios of these components, as well as different types sand according to grain density.

The weight of 1 cube of solution directly depends not only on its components, but also on humidity. According to GOST, based on average density, solutions are divided into light and heavy. Light solutions include mortars volumetric weight less than 1500 kg/m3. Heavy solutions, accordingly, include solutions with a volumetric weight of more than 1500 kg/m3. Heavy mortars are prepared using aggregates with a volumetric weight of more than 1200 kg/m3 and, when hardened, they have greater strength and density. Lightweight solutions, due to the presence of many air pores, have lower thermal conductivity. The weight of a cube of solution also depends on the size of the filler grains, as well as on the granulometric composition - the ratio of the filler grains by size. The greatest volumetric weight of the filler and, as a consequence, the solution will be if a certain ratio is observed between the number of grains of different sizes. For example, 1 m 3 of sand with grains with a diameter of 1 mm weighs about 1400 kg, and a mixture of grains 0.15-5 mm already weighs 1600-1700 kg.
And if you consider that sand is not the only type of filler, then we can conclude that the weight cubic meter complex solution can only be determined experimentally, by weighing vehicles, or approximately using tables:

Table Weight of 1 cube of solution depending on the type of binder and fillers

Name of solutions	Weight of 1 cube
Cement-sand mortar	1800
Complex mortar (sand, lime, cement)	1700
Lime-sand mortar	1600
Cement-slag mortar	1400
Cement-perlite mortar	1000
Gypsum perlite solution
Porous gypsum perlite solution

By observing different proportions of preparing the sand-cement mortar, you can obtain a base for concrete of any brand. Therefore, in this article we will talk about methods for obtaining mortars for pouring, masonry and other needs, considering a variety of proportions, as well as technologies for mixing components.

Components of cement-sand mixture and concrete

Such building materials consist of three mandatory components:

• binder - cement plays this role;
• filler - sand and a mineral component (crushed stone) are used in this capacity;
• water - it triggers the reaction of formation of cement stone, thanks to which the viscous building material gains strength.

A typical binder is Portland cement grades 400 and 500, less often 300 or 600. And the higher the grade number, the stronger the casting or masonry will be. In addition, the strength characteristics are also influenced by the proportions that determine the ratio of binder and filler. Typical fillers are sand and crushed stone. Moreover, the thinner the first component (sand), the greater the percentage of the second component of the filler (crushed stone). Therefore, for commercial solutions, use medium and coarse sand that has passed through a sieve with a cell diameter of 1.2 to 5 millimeters.

The sandy part of the solution should not contain clay. When obtaining commercial and greasy solutions, soils are separated in a stream of water using a washing procedure, since even a small volume of clay in the filler significantly reduces all the strength characteristics of concrete. Crushed stone in solutions is either gravel or granite. The size of the crushed stone fraction can be set in the range from 4-5 to 7 centimeters. However, the grain should not be more than 2/3 minimum distance between reinforcing bars. Therefore, in most cases, 40-50 millimeters of crushed stone is used for commercial solutions.

Water is supplied to the commercial solution in a proportion of 1:3 to 1:2 by weight of cement. A water-cement ratio of 0.3 and 0.5 ensures reliable hydration and high plasticity, and then hardness of the resulting mixture. And the liquid itself can be either drinking or industrial, but it must be clean. In addition, a number of additives are added to heavy and fatty solutions to improve the plasticity of the medium and the moisture resistance of the resulting casting. There are also reinforcing fiber additives that increase strength characteristics.

Household solution 1:4 or 1:5

Before diluting cement, most home-grown builders and finishers look at its brand. And if we have a composition of 400, then take four parts of filler for one part of the binder, maintaining a ratio of 1:4. Accordingly, for the 500th mark a ratio of 1:5 is used. These mortars have become a kind of household classic, used both for laying bricks and for pouring concrete foundations, tiles, pillars. In this case, water and crushed stone are added “by eye”, and the components are measured out not in kilograms, but in buckets.

The result is a moderately strong and frost-resistant solution, captivating with its ease of manufacture and low cost. However, very soon the slabs and plaster obtained in this way begin to crack not even from the load, but from frost. After all, when combining cement with sand, you need to focus not only on the mutual volumes of these components, but also on the mass fraction of water, crushed stone and various additives. Therefore, further in the text we will present industrial recipes, determining the exact consumption of cement and sand per 1 m 3 of standard mortar used for masonry, finishing and pouring.

Mortar for brick or block masonry

To connect individual blocks or bricks, we need a solution based only on loose filler. There shouldn't be any rubble here. Moreover, for loaded walls freight train will be determined by the ratio 1:3, and for unloaded ones - 1:4. In this case, the cement consumption per cubic meter of solution can be calculated in both liters and kilograms. And, according to the proportions, for a loaded wall it turns out that to 250 liters of binder we need to add 750 liters of filler (1 m 3 = 1000 l). And since a liter contains 1.4 kg of cement, the mass of the binder will be 350 kilograms.

The portion of sand is calculated by the formula 1 liter = 1.2 kilograms and equals 900 kilos. In this case, you need no more than 175 liters of water (350 × 0.5).

For an unloaded wall, 1 m 3 is divided into a 200-liter binder portion and an 800-liter remainder for filler. In terms of kilograms it turns out to be 280 and 960, but no more than 140 liters of water are needed. According to the recipe, the first option is similar to the M300 concrete grade, but does not have its strength due to the absence of crushed stone in the structure. The second option is similar to M200, at least this amount of binder is present in concrete of this particular brand. However, the real M300(B22.5) and M200(B15) used when pouring reinforced concrete products(concrete products) are prepared using completely different technologies.

Concrete for pouring reinforced concrete products

In this case, we will need grades with high strength characteristics B22.5 (M300), B25 (M350) and B30 (M400), which can withstand loads from 22.5 to 30 MPa. To produce such solutions in a volume of one cubic meter, you must follow the following recipe:

• For M300: mix 380 kilos of cement with a ton of sand and 830 kg of crushed stone, adding 175 liters of liquid. Mixing takes place in a concrete mixer, and a plasticizer is used as an additive (at least 6.2 kilos per cubic meter).
• For M350: 420 kilograms of cement are mixed with a ton of sand and 795 kg of mineral filler. In this case, when deciding how much water is needed, they focus on a water-cement ratio of 0.4 and pour 175 liters of liquid into a concrete mixer, adding 6.9-7 kg of plasticizers.
• For M400: 470 kilos of cement, a ton of sand, 0.76 tons of crushed stone and 175 liters of water are poured into a concrete mixer and mixed with the addition of 7.7 kilos of plasticizer.

Using M300, you can fill any household structure - from a path in the yard to the foundation for a low-rise cottage. In addition, this grade is used for elements of staircases and cast panels. But to achieve strength, you need to know how much and what to add to the concrete mixer, and follow the above recipe without deviation.

The foundations of factory workshops and large supermarkets are cast from M350. This grade is also suitable for panels and floors for multi-storey buildings. If you use the M350 at home, you won’t see how long such a casting will last. It will last longer than one generation of users. The M400 grade is used for pouring spans and piers for bridges, manufacturing monolithic bank vaults, and constructing foundations for special machines and presses. By preparing such a solution, you will receive concrete of very high strength, but its use in everyday life is unjustified due to the high cost of the components.

Cement based finishing mortars

For rough finishing of basement floors and arrangement of leveling screeds, it is better to use concrete grade M200. To prepare it, based on the yield per cubic meter, you will need 260 kilos of viscous substance (cement), 1.08 tons of sand, 900 kg of crushed stone and 155 liters of water. Mixing can be done manually (in a trough) or in a concrete mixer.

As plaster solutions It is better to use compositions containing cement in 1 cubic meter of the finished mixture, as in the option for laying bricks or blocks. Let us recall its composition: 280 kilos of cement, 960 kg of sand and 140 liters of water. To seal small cracks, chips and holes, you can use only a binder, but before diluting cement (without sand), take into account the high fragility of the hardened mass. That is, it is no longer possible to lay such a solution on the corners. And try to use no more than a liter of water per five kilos of cement.

The pace of construction also depends on the correct calculation of the required number of building materials. And if, for example, it does not cause any particular difficulties, then determining the cement consumption per cube of mortar can create certain difficulties.

How much cement will be needed per cube of mortar - what will be the consumption?

Determining how much cement is in a cube of mortar is quite simple. To do this, you need to know the ratio of aggregate and binder, as well as the density of cement (it is 1300 kg/m3). If a binder to filler ratio of 1:4 is used, then the mortar mixture will contain 20% cement. Considering its density, cement consumption per cube of solution will be 1300/5 = 260 kg (5 or so bags). The required amount of binder can also be calculated using special online calculators.

It is important to remember that the ratio of binder to aggregate is indicated in volumetric form, when calculating the number of bags of cement, you need to convert these values ​​into kilograms, taking into account the density of the material.

The easiest way is to determine how much cement will be used per cube of foundation mortar. To do this, you just need to calculate the total volume of the foundation (in m3). Then determine the volume of binder required to prepare a cube of concrete and calculate the total need for cement.

If it is necessary to determine the amount of cement for laying walls, the task becomes more complicated, since it is necessary to take into account the thickness of the mortar joint when calculating. To simplify calculations, use the average consumption of the solution for a cube of masonry. Practice has shown that about 0.25 - 0.3 m 3 of solution is consumed per cube of masonry. Therefore, when determining how much cement is per cube of masonry, it is first necessary to determine the volume of the building walls.

It has been experimentally confirmed that the amount of mortar per 1 m 3 of facing masonry ceramic bricks 13% higher than the required amount of mortar for laying other types of bricks.

From correct counting required quantity The entire construction as a whole depends on the binder. In case of error construction process may stall at the most crucial moment.

What affects cement consumption when making mortar?

When selecting the composition of the mixture, you need to remember that as the grade of cement increases, the need for binder decreases. In some cases, in order to maintain the structure of the mortar after setting, stone dust is introduced into it.

Cement consumption per cube of mortar depends on:

• type of solution. Depending on the purpose, sand, lime and clay mortars. For each of these solutions, the ratio of binder and aggregate differs. So, in order to cook cement-sand mortar, cement and sand are taken in proportions 1:3, 1:4. For lime - cement is added in a ratio of 1:3 to lime mortar. When using clay, cement consumption per cube of mortar is entered based on the calculation of 1:9;

• (determines the strength of the frozen mixture). The brand of mortar is selected depending on which element of the building it will be used in. For the foundation and load-bearing walls The strength of the masonry is of decisive importance, so it is recommended to use the most durable mortars. For interior walls mixtures with less cement consumption can be used. For plastering walls, you can use mixtures with a lower cement content;
• composition of the solution– selected ratio of binder and filler.

There is a direct relationship between the brand of mortar and the cement content in the mixture. The grade of mortar depending on the cement content in the mixture is shown in the table.

Brand of solution	in solution, kg
M10	81
M25	133
M50	178
M75	245
M100	306
M150	414
M200	510

The values ​​of cement content in the mixture given in the table are valid for 1 m 3 of solution.

Depending on the required brand of mortar, the classes of cement used, as well as the ratio of binder and filler, vary.
