The amount of cement in a concrete cube

During the construction of any object the estimate of the cost, which reflects the need for materials, and in particular: how much cement in 1 cube of concrete?

the question as necessary for a particular cement mortar construction of a clear and unequivocal answer does not exist.

To get accurate data, it is necessary to analyze the project documentation, and above all, working drawings.

The fact that a particular brand of concrete requires a certain amount of cement and inert materials - sand, crushed stone or gravel.

foundation required for a grade of concrete, and for the erection of walls and partitions, the other.The exact amount of materials required for construction, calculated according to some methods.

at present several types of cement produced while enterprises of the construction industry, which is used in major construction, decoration and renovation of premises.

most common brands that are used in all climatic zones, M300 and M400.

The raw materials used for its production of limestone and clay, which are mixed and heated to a high temperature.

As a result of this treatment is a material called clinker.And after the next redistribution of clinker and various additives to produce cement.

By adding different ingredients, is a material of a certain quality.

that consumers can quickly and accurately navigate the names and technical characteristics of the material, develop a clear notation.

The following codes can be reduced by way of example:

• B - time hardening solution;
• submarines - the presence of plasticizers;
• SS - there sulphate-resistant additives;
• N - cement clinker based on crumbs.

Some time ago ceased production of the brand M100 and M200.This was due to their weak technical characteristics.

Today, the most popular brands are considered M400 and M500.In individual housing construction is well-proven brand M300.

According to the applicable rules and regulations, the properties of cement are evaluated by two parameters.

first indicator - the ability to withstand the load.The second - the ratio of additive to total material.Thus, M400 withstands a load of 400 kg per cubic centimeter.

The amount of additives is indicated by the letter "D" and a number, which indicates the percentage of additives.

Here it must be said that the grade of concrete, which is required for pouring the foundation of an element is determined by the cement brand.

And in one cube of concrete it can be a different number.

In order to carry out precise calculations, developed a special table, which indicates the proportion of all materials included in the concrete and how many of them all.

Before the construction should be clear about how many bags of cement required for the entire object.In this case you need to know and how much goes to the binder cubic meter of concrete.

volume of sand and gravel to be determined more precisely, because these materials are worth the money.Performing calculations, it is necessary to take accurate indicators.The weight of one bag of cement can be either 50 or 40 kg.

on the working drawings showing all the concrete elements of the building, from the basement to the floor slab.Getting to the actual calculations, it is necessary to use these data.

All formulas to calculate simple and accessible for specialists with secondary vocational education.

Concrete brand M200

To determine how much cement is required for the mixing of one cube M200 brand of concrete, it is necessary to use the table in sets of rules.

The old edition sets of rules called SNIP.The table also shows data on how much of sand and gravel required.Data is given as per one cubic final product.

skilled in the art that the concrete of this brand can be kneaded using a different binder.In the case where the mark is applied M400, the concrete mixture proportions are such - 1: 2.5: 4.2.

the first position listed cement, then sand and gravel.

same cubic meter of concrete, mixed with cement brand M500, will have different proportions - 1: 3,2: 4,9.Sand and gravel in this version will take longer, and less cement.

can say in another way, the same amount of cement binds a much larger volume of gravel and sand.With the raw data necessary to calculate and weigh several options.

for laying the foundation have a specific need to use the binder mixture of high grades.In this case it is necessary to provide sufficient strength and durability.

Therefore, all solutions, which are set out in the project documentation, it is necessary to carry out, in spite of the desire to save money.

Concrete brand M300

concrete brand M300 is often used in individual housing.When using the M400 cement concrete mixture proportions are as follows - 1: 1.7: 3.2.

strength characteristics of the brand of concrete is higher than the previous.A binder is consumed more.Sand and gravel in the specific volume is used less.

When performed preparatory work, it is necessary to pay attention to the quality of inert materials.The sand must be free of river silt or clay.

Similarly rubble must meet certain standards, which are dictated by SNIP.

Concrete M300 brand can knead the M500 brand of cement.In this case, it is characterized by high strength and resistance to corrosion.A proportion per cubic meter of concrete will be the - 1: 2.2: 3.7.

If necessary, you can change the volume on the unit weight.And then, instead of cubes can handle tons or bags.

During the construction of small objects easier to count the number of bags than to calculate how many kilograms of cement in the cube.All the subtleties of this kind should be considered and applied in preparing cost estimates.

Concrete brand M400

Experienced builders know that the less cement in the concrete solution, the lower the reliability of the foundation.M400 concrete mix grade can be made of the same cement.

proportions in this case are as follows - 1: 1.1: 2.4.It should be recalled that, in these proportions is taken cement, sand and gravel.If necessary, it can be replaced with gravel chippings.

construction technologies know that the error can lead to lower quality of the concrete mix during kneading.

cement deficit will lead to the fact that after a year or a concrete foundation wall will begin to crumble.

If used for mixing concrete mix cement brand M500, it is necessary to withstand the following proportions - 1: 1.4: 2.8.

Some instructions recommending to cement brand was half higher than the solution brand.

must be said that such a precision that is shown in the calculations, in practice, to withstand very difficult.All the above formulas are intended to define the amount of cement in the same cube.

Knowing the volume of concrete structures, it is easy to calculate the required amount of cement for the whole construction.We must multiply this value by the amount of cement in a cube and should get the desired result.

Important conditions

The calculation does not need to get involved in counting the number of bags of cement, which is enough for all the work.It should be clear what is the concrete construction.

It is used for arranging the foundation for the erection of walls, laying of tracks, overlapping structures, beams and columns.This list can be continued.

From works manufacturer requires one - it should be understood that the amount of concrete grades determined by the number of objects.

And in each grade of concrete embodiment will be different.And bags of cement required a different number.

Keep records in bags need convenient and profitable.In some cases, taken a bag of cement, five bags of gravel and sand bags 3.

Concrete solution mixed in such proportions that meets all requirements.And this is not the only "trick", to which resorted builders with extensive experience.
