The consumption of cement per 1 cube of brickwork. Features of calculation, proportions and recommendations

Before every real man in life there are three primary tasks that he must perform in order to confirm his belonging to a stronger sex. And if there is no problem with the birth and education of the son, as well as the planting of a tree or even a whole garden, then building a house is a rather complicated process, which requires a long and persistent preparation financially, morally, but even more - "educationally".

Before the future architect in the process of work there will be a lot of problems, one of the priority - the purchase of building materials. To successfully solve this problem, you need to have a ready-made construction project, this will help determine the required amount of bricks, will allow you to calculate the consumption of cement per 1 cubic meter of brickwork and stock up the necessary quantity of other necessary components of the solution, avoiding unnecessary waste.

Do you want a strong house? Build correctly!

Specially trained people are engaged in professional construction. Even in order to be able to correctly lay the brickwork, you need to get a mason's qualification. Lead all processes on the construction site foremen. To the uninitiated in all the wisdom of the architectural business, it may seem to a person that in this kind of work there is nothing complicated at all, but in reality, it is possible to build houses in different ways, and each time one must observe many nuances.

Considered even such subtleties as the topography of the terrain on which the building will be located, its climatic conditions. On all this depends on the method by which the foundation of the house will be made, then, as the brick will be laid, what kind of mortar will hold the stones together. Knowing these and other factors will help to understand how much cement is needed for bricklaying, what characteristics the mortar must have for the walls to be strong, not to crack and skew after the first wintering, and not to become covered in mud.

Not so simple

Based on averaged indicators that indicate that the masonry is made with a width of one brick (with its long side equal to 250 mm), about 75 liters are needed per square meter of the mortar wall. But what is the consumption of cement per 1 cube of brickwork, if it is an interroom spoon, which is usually made in half a brick, or a thickened outer wall of 2-2.5 stone?

To determine the amount of mortar, and consequently, necessary for its mixing of cement, sand, water and other optional, but sometimes simply irreplaceable components, it is important to know several factors. This is the thickness of the seams, the structure of bricks and their size, and the proportions of the mixture themselves are an important factor affecting the consumption of cement per 1m3 and 1m2 masonry of various types of bricks.

Here are some data that will be useful for preliminary calculations, but it is worthwhile to understand that the material is always better to buy with an increase of 10-15%, this will save from a repeated visit to the construction site.

As can be seen from the table, the maximum cement consumption per 1 cubic meter of brickwork is equal to 250 cubes, but this value is valid for the thickest walls. The complexity of the calculations lies in the fact that the solution is not sold already mixed, and its main components are measured not in liters, but in kilograms.

What is mortar?

In everyday life, more precisely, at a construction site, it is rare when workers can hear a phrase like: "And bring me a bucket of solution!". Most often it is accepted to ask for just a bucket of cement, but it is worthwhile to understand that in addition to the fastener itself, other components also enter into the mixture. At the same time, in such a matter, as the consumption of cement per cube of masonry, the proportions of the solution are very important, and although they are set for an ideal environment, they may differ slightly in practice.

Traditionally, the solution consists directly of cement, which can be of different grades, meaning different strengths of the composition. For brick masonry, it is customary to take stamps with numbering M200 or M300, and a more "powerful" cement, M500, is usually required for pouring screed or forming concrete blocks, foundation. Other mandatory components are sand and water. So, the classical formula of a solution is 1 part of cement and 4 parts of sand, water takes about half the weight of cement.

Cement to cement

Why is this cement consumption per 1 cubic meter of brickwork - approximate, and do not blindly rely on the above formula. How to make an estimate for the order of all the necessary material necessary for mixing the solution is a question that often gives rest to inexperienced builders. As for the order of cement, you should know that it is sold in bags, their weight is 50 kg. If we calculate by weight, then for batching 1m3 of M150 mortar from M400 cement it is necessary to take 400 kg of cement, and for mortar with a strength of M 200 of the same cement 490 kg will be needed. When M500 cement is purchased, its consumption for the creation of a solution of the M mark is 150 - 330 kg, and the M 200 - 410 kg. These data are the consumption of cement per brick laying in 1 cubic meter, which are taken from generally accepted building codes.

Subtlety of batch

Sand - the second important component - is also sold from bases and quarries by weight. This material for the performance of work will require several times more, so talking about the purchase of sand per kilogram is inappropriate, it will be about tons.

Competent experts convince that when mixing sand-cement mortar it is important to make a mixture of suitable density, with which it would be comfortable to work. It is the sand that gives the necessary plasticity to the solution, on the contrary, the cement has a very fine grinding, because of which its particles are not able to significantly affect the density of the mixture.

Water in the solution should be poured in small portions, relying on weight, but not on the volume of cement. However, you can not pour out all the liquid at once, so that later you do not have to correct the situation, mixing the components over and over again. The fact is that it is impossible to predict in advance how pure sand will be, what its humidity will be, and also the weather conditions in which construction will take place.

In addition to sand, water and cement, the solution may include other components: lime, clay, mixtures that help to prevent the mixture from freezing, as well as additives that prevent the formation of whitish spots on the walls.

Brick to brick

How much cement should be needed per cubic meter of brickwork depends on the material with which the masonry will work. The use of large bricks (one-and-a-half and double) can reduce the volume of the mortar, but this statement is not entirely true for the hollow stone. With a kneading of cement, you need to be extremely attentive and careful. Too liquid mixture will penetrate into the voids, which, first, neutralizes the heat-saving and noise-isolating effect of the brick, and secondly, increases the consumption of sand-cement mortar.

Experts recommend mixing the mixture in such a proportion that during operation it was easy to apply a trowel to the working area of the masonry, and sewing seams did not become excessive work. The amount of cement consumed also depends on how much the mortar is applied to the brick. For masonry, which will later be hidden under the finish (siding, decorative plaster, lining), it is usually enough to apply a cement mixture on the central part of the brick. Then there is no need to design seams, which are also subject to very specific requirements. So, vertically positioned should not exceed a width of 8-15 mm, and horizontal - 10-15 mm.

Helpful Tips

Summarizing the publication, I want to mention a few more important points:

• Cement is a material that is not subject to long-term storage. Saturated with moisture, it "dubes" and turns into stone. In addition, it rapidly loses its astringent properties, under incorrect storage conditions this parameter is reduced by an average of 20% monthly.
• To get a quality solution, you need to choose the right sand. Ideally, it should be medium-grained, and its saturation with moisture should not exceed 7%.
• The shelf life of the finished solution is very small. After 1-2 hours after mixing the ingredients, the composition will no longer be suitable, therefore it is impossible to mix cement for future use.
