Cement consumption per 1 cubic meter of concrete: what it
The construction of most modern structures does not do without concrete work: pouring the foundation, walls, ceilings, etc. If you are building yourself, you should know the norms of cement consumption for the preparation of concrete.
Immediately it should be said that to call here a single digit will not work. A solution, like its components, may have different characteristics, based on its class / brand.

What is grade / brand solution
Material grade (for example, M-300) or class (for example, B-10) is the value of its compressive strength. This indicator is determined in factory laboratories on a cube of concrete, which has a side of 2 cm, after drying for 28 days under natural conditions.
Note! For different structures, a solution of different brands is needed. For residential buildings, M-100 / M-300 is usually used.
Plasticity fill

- In addition to water and cement, concrete contains fillers: crushed stone, gravel, sand. The standards concerning the grain size (fractionality) and the volume of weed impurities also apply to them.
- Based on the quantitative content of water and aggregates in the solution, its consistency may be different.. From the liquid (cast) - the mixture flows down from the spade to the non-plastic one - the material lies on the spade tubercle and does not spread.
- For pouring the foundation, floors, blind area, as a rule, they prepare material of average plasticity. He crawls from a tool tilted at an angle of 45 degrees, not spreading.
Cement selection

- Determining the cement consumption per 1 m3 of concrete, it should be remembered that it also has different grades. Its binding abilities depend on them.
- To prepare the mixture with the desired qualities, you should take cement that has a mark that is 1.5 / 2 times higher than the same amount of concrete. So, for the solution M-100 need cement M-200.
Note! During its long-term storage, the cement loses some of its qualities, even when it remains seemingly dry. On this basis, it is best to acquire this material before starting concrete work. If you are using stale cement, increase its volume in concrete by 10/20%.
Fillers
The mixture necessarily includes sand.
- Usually it is a quartz material having a fractionality of 1.1 / 3.5 mm.
- Smaller types of sand (although their price is not high), for example, loess, are not suitable for mixing mortar.
- Not suitable for material and filler, clogged with clay, silt, roots, grass.
- The sand forms a coarse structure of the mortar, facilitating its adhesion to the reinforcement. This increases the tensile strength of the structure. At the same time, cutting of reinforced concrete with diamond circles will help it.
In addition to sand, the components of concrete are large fillers: gravel, gravel, expanded clay, etc.

- Based on the type of such aggregate, the mixture can be ultralight, light, heavy, super-heavy.
- For example, granite crushed stone makes concrete heavy. Slag, tuff, and expanded clay are used to knead light analogs.
Water is a necessary component of the mixture.
- It should be clean and cold in summer, it can be heated in winter.
- Water from the aqueduct is suitable for mixing concrete, river - if not contaminated with organic matter.
- The instruction forbids the use of liquid containing solvents, oils, chemical reagents.
Components and calculation binder
The table shows the binder grades required to knead certain fill grades.
Brand of concrete | Brand of cement | |
recommended | permissible | |
M -50/100 | 400 | 300 |
M-150/200 | 400 | 300/500 |
M-250 | 400 | 500 and 550 |
M-300 | 500 | 400/600 |
M-350 | 500 | 550 and 600 |
M-400 | 550 | 500 and 600 |
M-500 | 600 | 550 |
The composition of the dry billet is calculated by weight of the components.
- In order to determine the cement consumption per cube of concrete for the foundation and other structures used in low-rise household construction, a mass ratio of binder, sand and gravel, equal to 1/4/4, is used.
- Calculated on the basis of the table in SNiP No. 5.01.23 / 83 or No. 82/02/95, water-cement ratio.
- It is necessary to find the desired class of concrete and the desired timing of its hardening, as well as the recommended brand of cement. This parameter will show the volume of water divided by the mass of the binder.
- The table contains data for heavy concrete on crushed granite. If construction gravel is used, 0.05 should be added to the figure.
- Например, вы определяете расход цемента на 1 м3 бетона м200. Период набора раствором окончательной прочности - 28 дней. Применяться будет цемент M-400 и как наполнитель - строительная щебенка.

- We find the CC for the sounded conditions - this is 0.56. Due to the use of rubble, add to the figure of 0.05, the result is 0.61.
- The volume of water, we determine, taking into account the desired plasticity of the fill, the type of aggregate and its fractionation. For a solution with rubble having a grain size of 20 mm, the figure will be equal to 205 l.
The final stage of calculation is finding the volume of the components in the material.
- To determine the consumption of cement m200 per concrete cube, like any other brand, it is necessary to divide the volume of water in the mixture by its water-cement ratio. In our case, it looks like this: 205: 0.61 = 336 kg.
- The weight of the remaining components is found, given the specified proportions 1/4/4.
For our example, you need a number of components:
- 336 kg binder;
- sand 1344 kilograms;
- gravel 1344 kilogram;
- water 205 liters.
The table shows the rate of cement consumption per 1 m3 of concrete, based on its class.

Conclusion
Having correctly determined the amount of binder in the material that you need to pack, you will create conditions for the quality of the batch. The created construction will be strong and durable. In case of need, after its final hardening, you will be able to carry out diamond drilling of holes in concrete.
