How to calculate the volume of concrete: what to use in the
Concrete due to its versatility is very popular during construction, as almost every stage involves the use of concrete products. The foundation, walls, ceilings, repairs - all this requires material.
Why do you need it
However, high-quality concrete is not cheap, so you need to know exactly how many consumables will be needed for a particular type of work. Every home craftsman should know how to calculate the cubic capacity of concrete.
This will help determine the total amount of consumables needed, as well as the total amount to be spent. However, this procedure is quite simple, all that is required of you - attentiveness and vigilance.
Tip: in the calculation itself, the formula for calculating the volume of the parallelepiped, which is studied in school, will help.
A bit of history
Each of us, if not alive, then in the photographs, saw the Egyptian pyramids known to the whole world, as well as the statue of the Sphinx. Yes, the amount of work done by the builders is simply colossal.
Many, perhaps, thought about where in the middle of the sandy country did so many boulders come from, and also how did they rise to enormous heights. However, people who are at least a little versed in construction can say with confidence that there was no place to look for huge boulders and nowhere to drag them anywhere. Moreover, boulders were not used at all.
As you know, Egypt is famous for a huge amount of sand. Sand, crushed stone, water and cement give as a result concrete - that's the whole solution. As you can already guess, stone blocks were made right up above with their own hands - they simply poured into the formwork and that's it. Of course, the scale of the work is still amazing, but this version is more believable.
And here the ancient Egyptians were faced with the problem of how to count the cubic capacity of concrete, as if:
- to cook it is not enough, you have to quickly make a new batch of the mixture;
- concrete will be in abundance, costs will increase, and the solution itself will have to be poured.
Payment
Before starting the process, you should decide in favor of one of the foundations, which are divided into three main types:
- slab;
- tape
- columnar.
| Slab | 1. The most simple in the calculation, since in this case it is necessary to simply measure the estimated length, height and width of the plates, and multiply the values obtained between each other. However, in some situations, such a foundation needs to be strengthened, which is achieved by adding in the form of stiffeners. Therefore, to obtain the total volume of concrete, it is necessary to calculate the volumes of slabs and stiffeners separately, and then add the resulting values. Since its price is the highest, the calculation will help not to spend extra money. |
| Tape | The calculation of the cubic capacity of such a base is somewhat different. Measure to begin with the perimeter of the future foundation2. Then multiply the result by depth and width. This method is applicable if there is the same section along the entire length of the foundation. For example, if a large load is planned on one of the sections, its section will be increased. Therefore, its volume must be calculated separately, and then added to the total. |
| Column | The column foundation consists of the supports of various sections connected by means of grillages. Find the volume of just one prop. 2. Since it has the shape of a cylinder, it is necessary to know the formula for finding its volume, which is equal to the product of the base area and height. 3. The resulting value is multiplied by the total number of supports used. |
In addition, making the calculation of the cubic capacity of concrete, it should be borne in mind that there are often various openings in the walls (doors, windows).
To calculate the volume of the concrete mix with their account there is a simple instruction:
- Count the total wall volume first.
- Calculate then the volume of openings.
- Subtract the second from the first value.
What to use
Of the tools that will be useful during the calculations, it is necessary to allocate only three:
- calculator;
- measuring tool;
- paper with a pen on which you will record the results.
However, technical progress does not stand still. Currently, a computer can not only build a 3D model of the future structure, but also calculate various quantities.
For example, there are many programs that help even in calculating the right amount of concrete mix, for example, an online calculator to calculate the volume of concrete with its help will not be a problem. They are quite easy to use, so everyone should understand the settings.
All that is required of you is to enter the configuration of the house, as well as its basic dimensions. You can even create a complete project of work, which will further facilitate the perception, and you will be able to see the result that you should end up with.
After that, the program will give the final result and will answer the question of how much concrete is needed. As you can see, such a process saves you time and also eliminates incorrect counting.
However, neither perfect calculation, nor calculation using the program, guarantees perfect accuracy. Therefore, it is necessary to add about 5-10% to the obtained value, since ideal surfaces are rarely obtained and this should be taken into account.
Tip: a small amount of additional concrete will save you from having to stretch and save the mixture to cover the entire volume.
