Cinder block house construction calculator. How to calculate the need for cinder block, and why this material is so popular

Cinder block is a building material for the construction of walls, partitions or foundations. It is made from slag concrete mortar, which includes slag, cement, expanded clay or other fillers, the proportions of all components are exactly observed. Before performing construction work, it is necessary to make an accurate calculation of the material.

How many cinder blocks in a square meter?

The cinder block has exact dimensions, they must meet certain standards, that is, 390 * 190 * 188 millimeters. Given the size of one block, you can get the exact number required material by calculation. First you need to calculate how many blocks go to one square meter.

Method number 1

With a wall having a thickness of half a block.

Knowing the height and length of the block, you need to calculate it side area, for this all quantities are converted to the SI system.

S=0.188*0.39=0.073 sq.m.

After the area is calculated, you can find out how many elements are in one square meter.

N=1:0.073=13.64 pieces.

This indicator is a little more than it actually is, since the thickness is also taken into account. connecting seam. When considering the thickness of the connection, this figure can be reduced to 13.

Method number 2

With a wall having a thickness of a whole block.

The calculation is performed in exactly the same way, first the area is calculated, and then the amount of material in one square meter.

S \u003d 0.188 * 0.19 \u003d 0.036 sq. m.

N=1:0.036=27.99 pieces.

If we take into account all the connections that will have a thickness of 8-10 millimeters, then 26 blocks will be needed per meter.

These are basic calculations, in order to find out a more detailed amount of all materials for construction, you need to draw up a detailed estimate. If the entire building will consist of a cinder block, taking into account partitions, walls, and the foundation, then first calculate the weight bearing walls, this indicator depends on the type of blocks. Cinder blocks can be full or hollow, their weight depends on this, which is 11-28 kilograms.

How to calculate the amount of cinder block per house?

The main indicators in the calculation are the dimensions of one cinder block, its weight, the element with emptiness has a mass of 17 kilograms, and the dimensions one-story building, for example, the height is 3 meters, the length is 8, and the width is 8.

1. First, calculate the perimeter of the entire building, multiply 8 by 4 sides, get 32 ​​meters.
2. If we divide the perimeter of the building by the length of the element, that is, 32:0.39, then we get the number of blocks in one row equal to 82.05 pieces.
3. Then the planned number of rows is determined, while the height of the wall is divided by the height of one element, 3: 0.190, and we get 15.78 rows.
4. You can find out the amount of material for a one-story building by multiplying the number of pieces in one row by the number of rows, that is, 82 * 16, it turns out 1312 pieces.

Thanks to such calculations, it is possible to determine the weight of the structure, that is, the load exerted on the base, for this, the weight of one element is multiplied by the number of pieces, that is, 17 * 1312, it turns out 22304 kilograms. With this calculation, the openings of doors and windows are not taken into account, this is done during accurate calculations, when they make up a detailed estimate. The weight of such elements is subtracted from overall indicator, and determine the load on the base.

The amount of the joint mixture depends on the thickness of the seams; when using glue, this figure should be no more than 3 millimeters, and for mortar - up to 10 millimeters.

Storage and transportation of the cinder block is carried out on pallets, so you need to know the number of blocks packed in one container. When building a foundation, they acquire blocks based on slag, and when building walls, you can use material with any fillers.

Basic counting rules for building a cinder block house

1. First you need to determine the dimensions of the cinder block, since the material does not always have standard parameters. The block of the partition type differs in size, 390 * 120 * 188 millimeters. That is, the product is pre-measured.
2. After that, the method of laying the blocks is chosen, that is, the position of the stone, during the construction of the wall. The amount of material needed and its consumption depend on this.
3. Then calculate the area of ​​the side face, and the number of blocks in one square meter.
4. And finally, the number of blocks in a row is calculated, how many rows are needed. Then you can define required amount material for the entire building.
5. First of all, it is necessary to draw up a detailed estimate with all calculations, taking into account the openings of doors and windows, this will make it possible to determine the load on the base, and what type of foundation to build.

Cinder block laying technology

1. the beginning construction works the construction of the foundation is considered, its width should not be much larger than the blocks. At the same time they perform perfectly flat surface, without chips, and significant differences.
2. Then the corners are set, rows are fixed at each corner, while taking into account the thickness of the block, and both seams. A rope is pulled between such elements to determine the level of the row being erected.
3. Laid on a fundamental foundation waterproofing material. At the same time, the foundation should protrude 70 centimeters above the ground, this will help prevent moisture from entering the soil to the base material.
4. Perform the laying of the material, the first row is provided Special attention, the final result depends on the quality of work. First, with a spatula, lay adhesive composition or a solution, and blocks are placed on it. After laying three blocks, it is necessary to measure the evenness with a level or plumb. The thickness of the connection should not be more than 1.5 centimeters. All cracks are closed with a solution; when using a hollow block, its interior is not filled.
5. Blocks are stacked in a checkerboard pattern, this increases the strength of the structure.
6. After laying, it is necessary to leave the walls until the solution has completely dried, and proceed to the external cladding. If further finishing is not planned, then a coloring agent, such as soot, can be added to the solution, this will help decorate the building, but you need to work carefully so as not to stain the main surface.

How to simplify the work?

There are small nuances to simplify the work, as well as save on costs.

1. For laying the cinder block does not require special tools. Use a level, a trowel, a container for mixing the solution, and a shovel.
2. The plasticizer is red clay, self-manufacturing this helps to save on material.
3. In advance, it is necessary to prepare a special stand on which the upper elements are laid out. It is not very convenient to work on a stepladder, since there is no place to put a bucket or put a cinder block, and it also needs to be constantly moved.
4. The thickness of the connection should not exceed 1.5 centimeters, otherwise a lot of heat will escape through it from the inside of the building.
5. Laying in half of the block is carried out for non-residential buildings, other methods can be used for the construction of residential buildings.
6. The preparation of the solution is carried out using a concrete mixer, this greatly speeds up and simplifies the work.
7. Immediately you need to prepare a file or handy tool for sawing blocks, as the corner parts consist of halves.
8. Work begins to be carried out from the corner elements, and the solution protruding from pressing is immediately cleaned with a trowel, if this is not done, then many irregularities form. This complicates further external finishing.
9. An experienced stacker can do the job using a level. If laying is done for the first time, then you can make a special template; for this, ordinary flat boards are used.

Before proceeding with the construction of the building, it is necessary to calculate the amount of material. To do this, all block sizes are taken into account, and a detailed estimate is made in order to be able not only to calculate the total amount, but also the costs. With correctly made calculations, you can avoid mistakes during construction work. It is important to follow all the rules for laying cinder block material, the strength, reliability, and durability of the building depend on it.

Starting the construction of a house, garage, bath, first of all, it is necessary to calculate the amount of building material that will be needed to build the foundation and walls.

Block construction is one of the most popular, fast and economical.

If you chose a cinder block for the construction of walls, you need to calculate how much cinder block do you need for a house. First of all, decide on the size of the house, if the foundation is already ready, then you need to calculate the total area of ​​\u200b\u200bthe walls.

To do this, calculate the area of ​​\u200b\u200beach wall - by multiplying the length of the wall by the height, subtract the area of ​​\u200b\u200bthe windows and doorways. Adding the area of ​​the walls, we get the total area. We decide on the width of the wall - half a block or a block.

To calculate how many cinder blocks you need for the whole house, you will need the dimensions of the cinder block. We measure the cinder block. Let's say that you have a standard cinder block, with a size of 390 * 190 * 190 * mm (respectively, 390 is the length, 190 is the width and height). If the width of the wall is half a block, then we calculate the area of ​​​​the side (wide) face of the cinder block: multiply 390 mm by 190 mm and get 74100 mm2, i.e. 0.074 m2.

We calculate how much cinder block will take per 1 sq.m, for this 1: 0.074, we get 13.51, round up to 14. Fourteen cinder blocks will be needed per 1 m2 of wall. Now calculate how many cinder blocks you need for the whole house. To do this, multiply the total area of ​​​​the walls by 14. If you are planning to build partitions from cinder blocks, add the area of ​​​​the partitions to the total area of ​​\u200b\u200bthe walls. Make allowances for the thickness of mortar joints.

cinder block is construction material for the construction of foundations, walls and partitions, buildings and industrial facilities.

It is made by pressing a solution of slag concrete prepared from: cement, sand, volcanic ash, crushed granite, broken glass or brick, crushed stone, crushed concrete, fine expanded clay, river gravel, slag.

To calculate the required number of cinder block units in 1m 2, simple calculations are used.

Calculation of the amount of cinder block per square meter of wall

According to the requirements of GOST 6133, standard cinder block is manufactured with dimensions of 390x190x188 mm and has a volume of 0.014 sq. m. Based on the known block size, it is possible to accurately calculate the volume of required building materials and the amount of cinder block. To calculate the approximate number of blocks in 1 sq. m, use simple mathematical techniques.

Option 1 - wall with a block floor thickness or 190 mm

A block-thick wall

Knowing that, the height of the cinder block is 188 mm and the length is 390 mm, its lateral area is calculated (after converting all values ​​​​to the SI system):

S side surface \u003d 0.188 * 0.39 \u003d 0.073 sq. m.

Now, knowing the area of ​​​​one block, you can calculate how many blocks will be required to build 1 square. m. walls.

N blocks in 1m2 \u003d 1 / 0.073 \u003d 13.64 pcs.

The obtained value is somewhat larger than the actual one, since we did not take into account the thickness of the mortar joint.

If we take into account the thickness of the seam of 8–10 mm, then in reality we will need not 13.64 pieces, but exactly 13 pieces.

Option 2 - wall thickness one block or 390mm

Block thick wall

The calculation algorithm is the same.

S side surface \u003d 0.188 * 0.19 \u003d 0.036 sq. m.

N blocks in 1m2 \u003d 1 / 0.036 \u003d 27.99 pcs.

And given the mortar joint, we need 26 pieces of whole blocks.

This initial stage calculations. To find out a more accurate quantity and consumption of building materials per facility, an estimate for construction work is needed, that is, it is necessary to calculate how much cinder block may be needed to build the entire house.

The total amount of work determines the total cost of the object, which consists of:

1. 30% - foundation, concrete mortar(addition of cement, sand, water, slag aggregates), reinforcing cage, earthmoving.
2. 45–50% - object walls, including bearing structures and jumpers.
3. 20–25% - roofing.

Suppose that the entire volume of construction work will be based on the use of cinder block - the construction of the foundation, walls and partitions. To calculate the number of products that put pressure on the foundation, you need to know the weight of the bearing wall, which depends on the type of cinder blocks used. It can be both solid and slotted blocks. Their weight varies from 11 to 28 kg.

Calculation of the amount of cinder block per house

We take as the basis for the calculations:

• The standard unit dimensions are 390x190x188 mm.
• The mass of the block with two voids is 17 kg.
• Dimensions one-story house- 8x8x3 m (Length x Width x Height).

Counting by rows of masonry - how many units of wall stone fit in one row. To do this, you need to know the dimensions of the block and the dimensions of the house. Then we calculate how many cinder blocks per 1 sq. m. will be needed to build a carrier box.

1. To do this, we calculate the perimeter of the house: P at home \u003d 8 * 4 \u003d 32 m.
2. To find out the number of units of products in one row, you need to divide the perimeter of the house by the length of the block: N pieces in 1 row \u003d 32 / 0.39 \u003d 82.05 pieces.
3. Next, we calculate the total number of rows. Wall height divided by height building block: N rows = 3 / 0.190 = 15.78 rows.
4. We find out the total number of blocks per house by multiplying: N total \u003d N pieces in 1 row * N rows \u003d 82 * 16 \u003d 1312 pieces.

Based on the results, it is possible to calculate the weight of the building, which will put pressure on the foundation: the weight of 1 pc. - 17 kg multiplied by the total number of units, we get 22304 kg. Since the preliminary calculation was carried out without taking into account window and door openings, they should be subtracted in the process of more accurate calculation, as well as their weight should be subtracted from the total weight of the load on the foundation.

Since the cinder block is usually stored on pallets, it is recommended to calculate the required number of pallets before buying it. One pallet holds 60 items. Therefore, based on the above example, for a house measuring 8x8x3 m, approximately 20 pallets will be required.

For the foundation optimal material there will be blast-furnace slag, any filler can be used for walls - fly ash, brick or stone rubble, crushed stone or gravel. To get a full-bodied product, 0.011 m 3 of working solution will be required to manufacture one unit of building stone. That is, from a bag of cement, 36 units of a standard size will be obtained with a bag weight of 50 kg.

The more precisely the equipment is set up, the less mortar will be consumed for laying blocks in rows, and the more products will be obtained from one bag of cement.

Affordable price, good performance characteristics, dimensions convenient for accelerated masonry are the main advantages that such a building material as a cinder block has. It has found wide application in the construction of capital residential buildings, garages, utility buildings.

Produce cinder blocks from a special concrete mix and slag, which are various construction and other wastes. They lay out the foundation, partitions, walls. The main advantage of the material is that it can be purchased ready-made or made at home.

Regardless of whether they use blocks of their own or factory production, the developer needs to clearly know how much material is required for one square meter of masonry.

What parameters affect the consumption of cinder block?

The number of cinder blocks per square meter of masonry depends on several components:

• block size;
• wall thickness;
• seam depth.

These parameters directly affect the consumption of building material. If you correctly take into account all the initial data, then it will not be difficult to make the correct calculation.

cinder block dimensions

There are the following types of this building material:

• corpulent full block;
• hollow full block;
• hollow block.

The first two types are produced in sizes 390x190x188, and the last - 390x120x188 and 390x90x188. Dimensions are in millimeters, the first digit indicates the length, the second - the depth, the third - the height of the block.

Seam thickness

Renders direct influence on the consumption of cinder block, but in the direction of decrease. This indicator is not always taken into account, especially when the savings do not have crucial. This approach is only suitable for small buildings. The amount of an extra block, if seams are not taken into account, for large buildings can be quite significant.

The thickness of the seams depends on the material:

• when glue is used, the seam is 2-3mm;
• if a solution is used, the seams are 5-10 mm.

The adhesive composition is not widely used, therefore, an indicator from 0.5 to 1 cm is taken into account. However, it is not taken into account in the formula, but is only subtracted from the obtained value, based on the number of rows.

Masonry thickness

Most important characteristic, which affects exactly how much cinder block will go into masonry in one square meter:

• in the floor of the block or 190 millimeters;
• in one block or 380 millimeters.

Therefore, the thickness of the wall is first determined, and then all the necessary calculations are already made.

Calculation of cinder blocks per 1 square meter of masonry

The calculation is made according to the following algorithm:

1. calculate the area of ​​the lateral base, that is, S=length*width;
2. find the number of cinder block per 1 square meter, that is, N = 1 / S.

Calculations are made exclusively in the SI system. This means that millimeters, that is, the width and length of the cinder block, are converted into centimeters.

An example of calculating the number of cinder blocks

If a standard cinder block (390x190x188) is used, the calculation is as follows:

1. 190 mm wall or block floor. The width and length are converted to centimeters, getting the values ​​0.188 and 0.39, then the side area is calculated, that is, S=0.188*0.39=0.073. Since the dimensions were converted to centimeters, the resulting value is already calculated in square centimeters, which allows us to proceed to the final calculation, that is, finding N=1/0.073=13.64 blocks. If we take into account the seams, then it turns out that when laying a block in the floor, about 13 pieces of cinder block are required for each square centimeter.
2. The wall is 390 mm or in one block. The calculation algorithm is similar to the previous version, but the values, of course, are different. In other words, S=0.188*0.19=0.036, that is, the side area is completely different from the first option, N=1/0.036=27.77, or approximately 27 pieces, if we take into account the thickness masonry mortar. Therefore, the wider the wall, the large quantity blocks to be purchased.

These calculations can be applied to absolutely any structure being built, built from cinder block.

Why calculate the amount of cinder block in one square meter?

This initial stage of calculation is necessary to determine the exact amount of material required for the construction of a particular building. Thus, knowing the consumption per 1 sq. m., it is not difficult to calculate and total costs on the material. If a garage is being built with masonry in the block floor, the wall area of ​​\u200b\u200bwhich is 51 square meters, then you need to purchase 663 cinder blocks. This number will double if the building is built with walls 390 mm thick. In addition, you should always remember that the material should be purchased with a small margin, given the possible marriage or damage to the blocks directly during laying.

Cinder block is a building material for the construction of walls, partitions or foundations. It is made from slag concrete mortar, which includes slag, cement, expanded clay or other fillers, the proportions of all components are exactly observed. Before performing construction work, it is necessary to make an accurate calculation of the material.

The cinder block has exact dimensions, they must meet certain standards, that is, 390 * 190 * 188 millimeters. Given the size of one block, you can get the exact amount of material needed by calculation. First you need to calculate how many blocks go per square meter.

Method number 1

With a wall having a thickness of half a block.

Knowing the indicators of the height and length of the block, it is necessary to calculate its lateral area, for this all values ​​are converted to the SI system.

S=0.188*0.39=0.073 sq.m.

After the area is calculated, you can find out how many elements are in one square meter.

N=1:0.073=13.64 pieces.

This indicator is a little more than it actually is, since the thickness of the connecting seam is also taken into account. When considering the thickness of the connection, this figure can be reduced to 13.

Method number 2

With a wall having a thickness of a whole block.

The calculation is performed in exactly the same way, first the area is calculated, and then the amount of material in one square meter.

S \u003d 0.188 * 0.19 \u003d 0.036 sq. m.

N=1:0.036=27.99 pieces.

If we take into account all the connections that will have a thickness of 8-10 millimeters, then 26 blocks will be needed per meter.

These are basic calculations, in order to find out a more detailed amount of all materials for construction, you need to draw up a detailed estimate. If the entire building will consist of a cinder block, taking into account partitions, walls, and the foundation, then the weight of the bearing walls is first calculated, this indicator depends on the type of blocks. Cinder blocks can be full or hollow, their weight depends on this, which is 11-28 kilograms.

How to calculate the amount of cinder block per house?

The main indicators in the calculation are the dimensions of one cinder block, its weight, the element with emptiness has a mass of 17 kilograms, and the dimensions of a one-story building, for example, height - 3 meters, length - 8, and width - 8.

1. First, calculate the perimeter of the entire building, multiply 8 by 4 sides, get 32 ​​meters.
2. If we divide the perimeter of the building by the length of the element, that is, 32:0.39, then we get the number of blocks in one row equal to 82.05 pieces.
3. Then the planned number of rows is determined, while the height of the wall is divided by the height of one element, 3: 0.190, and we get 15.78 rows.
4. You can find out the amount of material for a one-story building by multiplying the number of pieces in one row by the number of rows, that is, 82 * 16, it turns out 1312 pieces.

Thanks to such calculations, it is possible to determine the weight of the structure, that is, the load exerted on the base, for this, the weight of one element is multiplied by the number of pieces, that is, 17 * 1312, it turns out 22304 kilograms. With this calculation, the openings of doors and windows are not taken into account, this is done during accurate calculations, when they make up a detailed estimate. The weight of such elements is subtracted from the total indicator, and the load on the base is determined.

The amount of the joint mixture depends on the thickness of the seams; when using glue, this figure should be no more than 3 millimeters, and for mortar - up to 10 millimeters.

Storage and transportation of the cinder block is carried out on pallets, so you need to know the number of blocks packed in one container. When building a foundation, they acquire blocks based on slag, and when building walls, you can use material with any fillers.

The developer is always faced with the task of calculating how much cinder block do you need for construction. Help make cinder block calculator on this page. Just enter your details and our cinder block calculator will calculate how much cinder block you need to buy for construction.

How the cinder block calculator works

The starting point of the calculation is the dimensions of the cinder block.

Standard cinder block has dimensions: 390x190x188mm. We will assume that the area of ​​the side surface of the stone is 0.39 * 0.19 = 0.0741 m2.

From the area of ​​\u200b\u200bthe walls, it is necessary to subtract the area of ​​​​openings (windows, doors, gates), then we will get our calculated area of ​​​​the material.

Calculation of cinder block for a house

We take into account the number of layers of masonry (half a block, a block or one and a half blocks). Dividing the estimated wall area by the area of ​​one cinder block (0.0741m2), we get how much cinder block is needed for construction.

Knowing the perimeter, height and thickness of the walls, as well as the dimensions of the openings in the walls, we can easily calculate how much cinder block is needed for the walls.

Please note that the height of the walls is best calculated based on the number of rows of masonry. Divide the required building height by 0.19m. If you get a fractional value, then slightly increase or decrease the height of the building to optimize material consumption.

The thickness of the solution in the calculation formula is not taken into account. The consumption of cinder block is calculated taking into account a margin of 5% (losses per battle when carried to the place of laying, laying itself, etc.).

In the form of a calculator, the dimensions of each wall or opening are specified separately (they are often different heights, and the shape is not always a strict rectangle). Use the green "+" button to add the right amount walls and openings.

Enter the dimensions of the building and the cinder block calculator will give you an approximate figure for the required amount.

cinder block calculator

Attention, all dimensions are in meters!

Building materials have never been cheap, so it is very important to correctly calculate the required amount, then you don’t have to buy the missing one, spend extra money on delivery, or think about where to put unused unnecessary building material that spoils appearance yard and takes up space.

Calculating the number of cinder blocks for construction has a fairly simple algorithm. In order to understand the logic of the calculation, let's assume that we are building a wall of given dimensions without any openings.

The size of the cinder block, or rather its side surface, is 0.39x0.19, which means its area is 0.0741 m 2. Now, having previously calculated the area of ​​\u200b\u200bthe walls, we can easily calculate the consumption of cinder blocks for construction.

Let's say we decide to build a garage with standard sizes 4.5x6.5 meters and 2.5 meters high (these are 13 rows of cinder block).

Calculation of cinder block for a garage calculator

We consider the area of ​​\u200b\u200bthe walls of the garage: 6.5 * 2.5 * 2 + 4.5 * 2.5 * 2 \u003d 32.5 + 22.5 \u003d 55m 2.

Haven't forgotten anything? That's right, we still have a gate ... Let's say we have a gate in the garage with dimensions of 3.2x2.1 meters. The gate area is 6.72m 2 . Then total area walls of the garage minus the area of ​​the gate will be: 55-6.72 \u003d 48.28 2.

Now let's calculate the required amount of cinder block: 48.28 / 0.0741 = 652 pieces.

But we calculated this on the basis that the entire cinder block will be laid perfectly and not a single block will be broken during transportation, reloading and laying. In practice, unfortunately, this never happens. Therefore, it is better to take a cinder block with a small margin, for example, around 5%. In our case, it will turn out: 652 * 1.05 = 685 pieces.

Good luck with your construction!
