How to calculate the consumption of cement, based on its brand

difficult to underestimate the importance of the construction works of such material, such as cement, but its popularity is largely dependent on brands, among which are the most and least used.In particular, it is often preferred for low-rise residential buildings makes 300 and 400 have a different flow, for example, one square meter of fill 10 centimeters thick will need 50-pound bag of cement M400, and a fifth of the left, but the M300 will require 51kg, that is, the bag is not enough.Logically, it is for the brand M150 solution, because M200 is more commonly used cement 400 and 500.

Usually cement consumption calculation is made in cubic meters. Knowing that for 1 m3 of concrete from cement brand M300 M400 need 600 kilos, we have calculated the amount of the main component of the solution to fill the 10 squares of the floor screed thickness of 10 centimeters .It is very important before you calculate the consumption of cement, learn the recipe mixes in exact proportions, for which there are building codes, from which the need to take all the data.Thus, according to SP 82-101-98, for the preparation of solutions 150 and 200 when using certain brands of material necessary to comply with the ratio:

proportions of cement sand and lime (clay) dough mixture M200
M500 1: 3: 0.2
M400 1: 25: 0.1
cement proportions of sand and lime (clay) dough mixture M150
M500 1: 4: 0.3
M400 1: 3: 0.2
M300 1: 2.5: 0.1

How to calculate the cement - simple math

For example, we need a continuous footing, the situation is fairly common.The parameters we know it, let them be as follows: length 20, width of 0.4 meters and a depth of 0.5.The solution will take cement and sand in the standard ratio of 1: 3, but not concrete rubble as a filler, it was easier to find.The volume of the foundation will be 4 cubic meter, for us as a solution of cement, of course, do not need much of the take sand and water, which we need not more than 6 shares (so much and take).

So the solution we must have a total of 10 shares of the components that cube solution cube powder yields 0.1, and for the foundation we need 0.4 cube of material.However, apart from how to calculate the volume ratio of cement, it is necessary to take into account its density and that for the solution of the example is 3000 kilograms per cubic meter.If we multiply the required amount of material on its density, we obtain the desired weight, ie 0.4 * 3,000 = 1,200 kg.If the material is packaged in bags of poltsentnera, we need 24 bags.
