An online calculator will help you quickly find out how many cubes of concrete will be needed and calculate the volume. Thanks to a quick calculation, you will find out the number of cubes, you just need to specify the data and the thickness of the concrete slab and get the finished result. The calculator calculates concrete cubes for floor screed.

In order for construction work to proceed efficiently and without delay, it is necessary to provide the required amount of building material. When implementing a floor screed, you need to know how much concrete is needed to complete this work.

How to calculate the number of concrete cubes correctly in order to avoid unnecessary costs and the presence of low-quality material? Calculations can be done very simply using the online concrete volume calculator.

## How to calculate the volume of concrete for laying a floor?

Using a concrete volume calculator, you can make the most accurate calculation of the required materials for construction in a few minutes. To do this, you need to enter the geometric dimensions of the area of the room into the prepared table, using the formula we find out the area m ^{2} and enter this value. We measure the average thickness of the screed and enter this value into the table.

Then press the "calculate" button and get ready-made data online, so that there are no problems with the final result in terms of numbers, you need to increase the final readings by 10-15%.

In this way, the calculation of the concrete volume with a calculator is performed in a matter of minutes, now you will find out how much concrete mix you need to purchase. Please note that the thickness of concrete in the calculator table in meters is indicated by default!

## Features of using a floor screed solution

So that the final result in terms of calculating the volume of concrete for construction work on the floor screed does not radically change, several factors must be taken into account when doing this:

- the area of the premises where the repair is planned;
- original floor amount; the thickness of the concrete pouring layer will depend on this indicator;
- cement grade and sand quality.

## How to calculate the required amount of concrete manually?

If you want to check the obtained data with the calculation of the concrete volume with an online calculator, then for this you need to take the data on the area of the room for the floor screed and multiply by the desired layer thickness.

But in fact, not everything is so simple, a complicating circumstance in such a case will be the determination of the required thickness of the screed, and after all, it will be different for different types of buildings.

The peculiarities lie in the expected load on the floor, for example, in residential premises these indicators are up to 5 cm, for the strength of the coating, and in non-residential premises - half less.

Thus, if the area of the room is 20 m ^{2}, then with a thickness of 5 cm, the final figures will be as follows: 20m ^{2} * 0.05m = 1 m ^{3}, this is how much mixture is needed to screed the floor.

## What is the best composition for floor screed

Before calculating the amount of concrete for the screed, you need to decide which brand of mortar to choose. The best option would be a solution marked M 150 or M 200, you can get such a mixture from M400 cement, if you mix it with sand in a ratio of 1: 3, or to two parts.

Now you need to calculate the volume of concrete with a calculator:

- room 29 m
^{2}; - screed thickness - 5 cm;
- required volume - 1m
^{3}; - cement will be 0.24 m
^{3}(4 parts in total); - sand - 0.75 m
^{3}.

Taking into account the weight of one cube of each component unit separately, we get the following data: if we take the average indicators - 1300 kg for cement and 1625 for sand, then we get 325 and 1220 kg of each component, respectively.

When preparing materials, it is necessary to take into account the shrinkage of the solution, which often gives a result less than expected by 10%. It is necessary to make an appropriate stock, so that later separately do not make a new batch.

## Expert advice

When calculating the volume of concrete with a calculator or manually, you need to carefully double-check the data, and only then make the final purchase of building materials. And in this situation, it's not even about money, but about the quality of the work performed, how reliable and durable the floor will be.

If you use a calculator to calculate the floor screed, then you must first decide what brand to make the screed, how to strengthen it, how economically you want to approach this matter.

To save concrete, a coarse fraction, for example, gravel or slag, can be added to half of the floor.

If we talk about the mass of the screed, then it can be done independently, we use the following proportion: on one part of the cement we put two parts of sand and three parts of crushed stone, or weeding out. You can also make a composition only of sand and cement, each master has his own methods, taking into account the characteristics of the initial state of the place for laying the floor. Calculate the required amount of sand and cement faster with a calculator.

In order to strengthen the screed, they use a reinforcing mesh, fiber, such material is attached to the base, and the fiber intervenes into the concrete for screed.

## What tools are used for the screed device

Before calculating the volume of concrete with an online calculator, you need to prepare a number of tools that will be needed for high-quality and fast installation:

- for a large amount of mixing, a concrete mixer will be needed, and when using shovels, this process will be long and laborious;
- beacons to ensure an even screed;
- laser and normal level, the more accurately the upper point of the floor is determined, the better and more economically the work will be done;
- and you will also need trowels, shovels, construction wheelbarrows, buckets, etc.

It must be remembered that a high-quality screed will depend on the drying of the floor after the work is completed, good ventilation will help remove excess moisture that will appear when working with cement mortar. A detailed video about self-screed floor.

When laying the cement mixture, the base must be dry and clean, and it is best to prime it with special penetrating compounds, which will provide a good connecting function with the laying mixture.

There is a more economical and faster option. This is a dry floor screed. This method is very suitable for apartments and houses where repairs are required as soon as possible.

Conclusion

Now you know how to calculate the volume of concrete with a calculator online or do it manually using simple mathematical calculations. A quick and high-quality repair for you, be careful and follow the safety rules when working with cement mortar!
