Before every real man in life there are threethe primary tasks that he must perform in order to confirm his belonging to a stronger sex. And if there are no problems with the birth and education of the son, as well as the planting of a tree or even a whole garden, then the construction of the house is a rather complicated process, to which it is necessary to prepare materially, morally, and even more - "educationally" - for a long time and persistently.
Before the future architect in the process of work will arisea lot of problems, one of the priority - the purchase of building materials. To successfully solve this issue, 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 for 1 cube of brickwork and stock up the necessary number of other necessary components of the solution, avoiding unnecessary waste.
Do you want a strong house? Build correctly!
Professional constructionspecially trained people. Even in order to be able to properly 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 fact, houses can be built in different ways, and each time one must observe many nuances.
Even such subtleties as topography are taken into accountthe location on which the building will be located, its climatic conditions. From all this depends on the method by which to make the foundation of the house, then, as they will lay the brick, which mortar will bind the stones together. The knowledge of these and other factors will help to understand how much cement is needed for bricklaying, what characteristics the mortar should have to ensure that the walls are strong, do not give a cracks and distortions after the first wintering, are not covered with soles.
Not so simple
Based on the averaged indicators thatdenote that the masonry is made with a width of one brick (long side of it is equal to 250 mm), one square meter of the mortar wall needs about 75 liters. 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 solution, arespectively, necessary for its mixing of cement, sand, water and other non-mandatory, but sometimes simply irreplaceable components, it is important to know several factors. This is the thickness of the joints, 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 you from re-visiting the construction site.
Type of masonry by thickness (bricks) | Standard brick (m3 of solution) | One-and-a-half bricks (m3 of solution) |
0,5 | 0,189 | 0,160 |
1 | 0,221 | 0,200 |
1,5 | 0,234 | 0,216 |
2 | 0,240 | 0,222 |
2,5 | 0,245 | 0,227 |
As can be seen from the table, the maximum consumption of cementfor 1 cube 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 the construction site, rarely whenworkers can hear a phrase like: "And bring me a bucket of solution!". Most often it is accepted to ask for 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 question as the consumption of cement on the cube of the masonry, the proportions of the solution are very important, and although they are established for an ideal medium, in practice they may differ slightly.
Traditionally, the solution consists directly ofcement, which can be of different brands, meaning different strength of the composition. For brick masonry, it is customary to take stamps with numbering M200 or M300, and 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 brickmasonry - approximate, and do not blindly rely on the above formula. How to make an estimate for the order of all the necessary material needed to mix the solution - 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 calculations are carried out by weight, then for mixing 1m3 of M150 mortar from M400 cement, 400 kg of cement should be taken, and for mortar with a strength of M 200 of the same cement 490 kg will be needed. When the cement of grade M 500 is purchased, its consumption for the creation of a solution of M mark is 150 - 330 kg, and M 200 - 410 kg. These data - the consumption of cement per brick laying in 1 cube, which are taken from the generally accepted building codes.
Subtlety of batch
Sand - the second important component - also realizesfrom bases and quarries by weight. This material for the performance of the work will require several times more, so talking about buying sand per kilogram is inappropriate, it will be about tons.
Competent experts convince that during the batchsand-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 in the solutionmay include other components: lime, clay, mixtures that help 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 do you need for a cube of brick masonry,depends on the material with which to work. The use of large bricks (one-and-a-half and double) allows to reduce the volume of mortar, but this statement is not entirely true with respect to the hollow stone. With a kneading of cement, you need to be extremely attentive and sensitive. 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 aproportions, so that during work it was easy to apply a trowel to the working area of the masonry, and sewing the 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 subsequently 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 tolong-term storage. Saturated with moisture, it "dubes" and turns into stone. In addition, it quickly 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 components, the composition will no longer be suitable, therefore it is impossible to mix cement for future use.
