Calculation of the number of building blocks. How much does it cost to build a cinder block garage - calculating the number of blocks

Before proceeding with the direct construction of the building, you need to make some calculations. To do this, we will consider all options for the amount of material in area and volume, as well as determine the weight that will matter when loading on the base.

We consider the material in all respects

By and large, we need all these parameters not only to understand how many cinder blocks we need per house, but also to draw up a fairly accurate estimate for the entire construction.

Here we explain that the cost of the entire structure is approximately distributed as follows:

• 30% - foundation, concrete, reinforcement, plus earthworks.

• 45-50% - house box, load-bearing structures, lintels.

• 20-25% - this is a roof, together with materials and the cost of work, here we will not be able to build everything on our own.

Where to begin

Since we are going to build from scratch, the first thing we will do is develop the foundation. To do this, we will need not only a geological analysis of the soil, but also the collection of all loads, and this is where our first question arises, how much does the cinder block weigh.

The answer, of course, depends on the type of product and dimensions, but let's put it this way:

• from 16 to 20 kg, if we are talking about hollow material;

• from 22 to 28 kilograms, if we are talking about a full-bodied block.

Full-bodied variant

Now let's define overall dimensions material and design dimensions of the house - dimensions.

To make everything work out clearly for us, we will calculate how much 1 cinder block weighs and how much will be used for construction based on the following parameters:

• Material dimensions - standard 390 * 190 * 190 * mm (respectively 390 - length, 190 - width and height).

• The weight of the product with two voids in the body is 17 kg.

• The dimensions of the house are 8x8, with a wall height of 3 meters.

• The building is one-story, we will choose this option for a simplified consideration.

• The attic as an addition will be considered at the end.

So, now that we have all the initial data, we can proceed to several calculation options, where we will find out everything we need to start construction works numbers.

Counting Methods

Reveal required amount material can different ways. We will offer several, and you yourself will choose which one you will use in your work.

In the first option, we will go through the rows of masonry, and for this we need certain data:

• Block dimensions (for example, standard sizes of cinder blocks).

• House options.

Number of rows

The length of our house is 8 meters, as is the width. We agreed to use a height of 3 meters. Next, for the construction, select a standard block 390*190*190* mm.

We need data on the perimeter, for us it is, as always, the sum of all sides, that is, 32 m.

• We divide the length of the perimeter by the length of one cinder block and get 32 ​​/ 0.39 and get 82.05. That is, we will have 82 products in one row of masonry.

• We calculate the number of rows. We divide the height of our walls by the height of the product and get 3 / 0.19, a total of 15.78, that is, we have 15 nearby.

• We multiply the number of rows by the size of the blocks and output 1230 blocks.

This calculation does not answer so much as cinder blocks per square meter, but gives us the opportunity to understand the level of load on the foundation. And since we touched on this, we will immediately make this calculation.

Strip foundation for a cinder block house

We agreed that the weight of one piece - 17 kilograms, which means that 20910 kg, a little more than twenty tons, will be released onto the supporting structures.

Important! The calculation of the value of the blocks was carried out without taking into account the jointing and window and doorways. The same applies to the collection of loads.

Since we stopped at the loads, we immediately apply a simple formula for calculating the weight of the glue that we will use when laying. Manufacturers indicate that it takes about 5 kilograms of glue per square, respectively, we have 480 kg.

We proceeded from the standard indicators from the manufacturer and took into account the thickness of the seam of 3 mm during laying.

And now we will find out how many cinder blocks are in 1 m2 and there is also a very simple formula for this.

We take the dimensions of our material, recall that it is 390 X 190 X 190 mm and multiply the length and height, that is - 0.39 * 0.19 \u003d 0.0741 m squared. Next, we divide the required values ​​\u200b\u200b- 1 / 0.0741 \u003d 14.49.

So, in one square of the wall area, we can fit 14 and a half pieces of cinder blocks.

Square meters of masonry

Important! This figure characterizes a wall with a thickness of 19 centimeters. If we decide that the thickness of the bearing wall should be greater, then we will have to recalculate the amount of material that will be located in one square.

And now, when we have all these figures, we can more specifically answer the question of the required value of the pieces of the product for bearing walls including window openings.

Here the instruction assumes that the windows will be 1500 mm by 1300 mm, or 1.95 m. window openings we have 7, for example, it turns out, 7 * 1.95 = 13.65. Total total wall area, 96 - 13.65 \u003d 82.35. And this, in turn, is 82.35 x 14.49 = 1193 products!

Here you can also reduce our initial load on the base of the house. Glue - 5 * 18.35 = 91.75 kg, wall weight, 1193 * 17 = 20281, almost 700 kg was reduced from the load.

There is another option in which we are interested in how many cinder blocks are in 1 m3, this type of calculation will help us better navigate the acquisition of material, because it is sold in cubic meters.

Material in stock

Here the formula is also quite simple, and will require us to enter accurate data on the dimensions of the product. The volume of our standard product is equal to the derivative of the addition of all quantities, which is 0.014 cubic meters.

Thus, to the question, how many pieces of cinder block are in 1 m3, we can easily give an answer - 71 pieces. We will not continue to make calculations, we already have a basis for a long time and we are well aware of any figures.

Option with an attic

This is the last point that may raise some questions for us, and even then of a purely "geometric" nature. The fact is that the principles for calculating the area of ​​\u200b\u200bthe pediment take into account the fact that it is a triangle. And we have to start from that.

Attic option

In our case, the area of ​​​​one gable will be 16 m, both 32, minus the windows, let's say we have one on each side, total: 32 - 3.9 = 28.1, or 408 pieces of material, to be completely pedantic!

Price

This is an important parameter

Since we have touched on the issue of finance, the price of one cubic meter of cinder block will be approximately at the level of 2,500 rubles.

Important! We say right away that any references to the price should be adjusted by the cost of the product in your region!

Let's look at the price differently. We know that we have 71 block pieces in one cube, in different regions the price is different, but we take the cost of one cinder block from 33 rubles per item and get 33*71=2343

We can immediately assume that our house, or rather the load-bearing walls of the first floor on cinder blocks, will cost us 39,369 rubles. Agree, the price is simply unrealistically low.

Pallet option

Often the purchase is by pallets, so we need to know how many cinder blocks are in a pallet in order to accurately determine the required values ​​\u200b\u200bfor the purchase.

As a rule, one pallet is designed for 60 pieces of a product, that is, it falls short of a full-fledged one quite a bit. cubic meter. Us for the construction load-bearing structures the first floor, with all our calculations, it will take about 20 pallets.

Finished pallets

Conclusion

We have tried to answer in detail and informatively all questions regarding the possible values ​​in the use of our material.

cinder block- This concrete block containing slag. There are many varieties of slag, but for the manufacture of building material only blast-furnace is used, which differs useful way out and impeccable qualities for construction. Sometimes inexpensive fillers are used: brick fight, shell rock, brick fight. To increase the level of thermal conductivity, polystyrene, expanded clay or perlite is added to the composition.

Cinder blocks are used to build houses, outbuildings, garages and fences. The material has its own characteristics that must be considered during construction:

• Cinder blocks are of two types: full and hollow. For walls you need to choose hollow. And full-bodied, more durable, builders use to build the foundation.
• Construction material does not like moisture, this must be taken into account when creating a foundation of cinder blocks. It can only be erected for small buildings on dry soils.
• Construction from cinder blocks saves time and money, it is not necessary to hire professionals, all work can be done independently.

Some mistakenly believe that a cinder block building is an unreliable structure, but in fact the life of the material is more than 50 years.

Where to start building?

Before you build a garage from cinder blocks with your own hands, you need to carry out preparatory work:

• conduct a geodetic assessment of the area;
• estimate the distance to communications (light and water);
• develop a garage project, taking into account all the details;
• determine the type of masonry, calculate the quantity and cost of materials.

The project is the basis of all work

Many novice builders are often intimidated by this word, believing that it will take a lot of time to create a project and you will have to deal with a huge number of drawings. In fact, this is not so, it is enough to draw on one sheet of paper what the garage should look like. The drawing will help to systematize the work and speed up the process.

Before you start building, think about what purpose your garage will have.: you will only store the car in it or do repairs, whether you need viewing hole or cellar, room size, etc.

We build a garage from cinder blocks

How to build a cinder block garage? Construction is divided into several stages, this helps to better navigate during work:

1. Foundation creation. Cinder blocks are a fairly light material, so you can choose a strip foundation.
2. Arrangement of the basement with protective vapor barrier and heat-insulating materials.
3. Construction of a cinder block garage.
4. Floor screed.
5. Creation of ceilings and roofing works.
6. Gate installation.
7. Final works: connection of electricity, internal and external finishing.

How many cinder blocks do you need for a garage? How to correctly calculate the number of cinder blocks?

Before starting construction, the required amount of material is calculated. For this you will need:

• paper;
• roulette;
• calculator;
• pencil.

First, determine the size of the cinder blocks. Standard - 390x188x190 mm, often there are varieties with dimensions of 390x188x120. If you are in doubt about the size of your cinder blocks, it is better to take measurements yourself, great importance has a face that will be located on the outside.

For example, if you are building a wall to the floor of a block, then you first need to calculate the area of ​​\u200b\u200bthe face.

How many cinder blocks do you need for a garage? To calculate the material per 1 sq.m. you need 1 / 0.074 \u003d 13.51, round the value, it turns out 14. Be careful, you can only round the resulting number up.

Let's give a simple calculation example. For a garage 7x5m and a height of 2.5 m, 717 cinder blocks will be needed. To calculate the amount of material, you need to make the following calculations:

1. Garage perimeter: (7+5)*2= 24 m.
2. Wall area. We multiply the resulting perimeter by the height: 24 * 2.5 \u003d 60 sq.m.
3. goal area. It must be calculated and subtracted from the total area. For example, if the gate is 2.5 * 3.2 = 8.75 sq.m, then 60 - 8.75 = 51.25 sq.m. (this is the area of ​​all the walls).
4. Calculation of the number of blocks for a cinder block garage. The resulting area is multiplied by the number of blocks required for 1 sq. m. 51.25 * 14 \u003d 717 blocks.

But it is better to take a little more material, given the possible damage or marriage.

Cinder block foundation for a garage

The construction of cinder blocks is not heavy, it is not necessary to create a solid foundation. The depth of the bookmark depends on the freezing of the soil, the passage ground water and type of soil (sand, clay, rocky terrain, etc.) The foundation for a cinder block garage can be built in several ways.:

1. Removed first upper layer site, then a trench is dug. It is filled with several layers: sand, cobblestone or broken brick with sand. Both layers are impregnated with cement mortar to protect against damage and melt water.
2. A trench 40 cm wide and 50 cm deep is dug. A layer of sand is poured onto the bottom, filled with water and well compacted. This will make the foundation strong and durable. Then reinforcements are placed on the bottom so that they have different directions. The structure must be concreted and allowed to stand for at least 30 days.
3. The third method is the simplest, it is called rubble concrete. Rubble stone is laid in layers in the trench, poured with cement. It is important to use cement not lower than 150 grades. Mix Portland cement with sand at the rate of 1 part of cement to 2.5 parts of sand. Add water until a movable mixture is obtained.

Foundation waterproofing

To do this, you need to cover the foundation with roofing material, laying it a few centimeters more area construction. Gates are installed on a strut.

Building the walls of the garage

There are no special rules and secrets of masonry. Builders use the principles of working with bricks. Laying can be carried out in the following ways: spoon (on the floor of a stone) and bonder (in one stone), in 1.5 or 2 stones. The ability of the garage to withstand low and high temperatures, gusts of wind.

The most common method of building walls- “brick”, when the next overlaps the seams of the previous row. First you need to lay out the corners, then stretch the cords between them and continue laying the cinder blocks.

Floor arrangement

The floor is built at the basement level, the thickness of the screed must be more than 10 cm. First prepare the surface: clean construction garbage, level the surface, if necessary, pour fine gravel or sand on the bottom.

Prepare concrete for screed, it is better to purchase ready-made M200. The mixture is poured continuously in several layers, and when the concrete has set, you can start rubbing the surface.

Roofing

To create a roof, I-beams are required 25 cm longer than the width of the garage. The beams are laid across, the step is about 80 cm. Next, they are sewn with the help of bars 40 mm thick, they are placed close to each other. Lay roofing material on the bars, expanded clay, slag or semi-rigid mineral plate on top, make a 20 mm thick screed, cover the roof with rubemast or aquaizol.

Final work

At this stage, carry out external and internal Finishing work . A cinder block garage does not require any special actions. If desired, you can plaster, rub with cement or whitewash the walls, sheathe with clapboard. You can also insulate the room with foam or fiberglass, protect it from moisture with polyethylene film, to make a GKL patch.

A cinder block garage with a finish looks no worse than a brick or other building. The design is reliable, safe and durable. Finishing of external and internal walls will make the room comfortable and cozy.

The construction of a garage must begin with a study of the territory, drafting a project and calculating the amount of material.

cinder block- durable and economical material, allowing you to create a garage yourself without the help of professional builders.

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 total area 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 ​​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.

Let's calculate how much cinder block will take per 1 sq.m, for this 1: 0.074, we get 13.51, rounded 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 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 number required material 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 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 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 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 determine the required amount of 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 construction of the foundation is considered the beginning of construction work, 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 this.

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 the unused unnecessary construction material which 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 the total area of ​​the walls of the garage minus the area of ​​the gate will be: 55-6.72=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!

One of the most popular building materials is currently considered to be cinder block. His excellent performance characteristics and ease of operation are key drivers of sales growth. The popularity of this building material can also be indicated by the fact that a lot of questions, such as how to calculate the amount of cinder block per wall, are asked today.

In full accordance with its name, this material is based on slags formed in blast furnaces. However, additives such as crushed stone, sand, brick and even concrete are not excluded. In addition, there you can find expanded clay, perlite and even sawdust. All these additives affect the properties of cinder blocks in one way or another. Which we will talk about next.

What properties do cinder blocks have?

In the case of adding perlite or expanded clay, the material is obtained as light as possible. If you add sawdust to it, you can also get a fairly fire-resistant option. In the event that cement, crushed stone or sand are added to the cinder block, the material turns out to be heavy and conducts temperature quite well.

The parameters of these products are as follows:

• The standard dimensions of the cinder block are 188x190x390;
• Frost resistance index - F15–50;
• Thermal conductivity - 0.27–0.65 watts per square meter;
• Density - 750–1,450 kilograms per cubic meter;
• Strength - M35-M125.

Solid and hollow cinder block

full bodied. An extremely durable building material that is used at the most critical stages of construction.

Hollow. The number of voids, depending on the volume, can be 30 or 40 percent. Can be used for building walls. However, the most hollow options can only be used in conjunction with metal frame. Otherwise, the strength of the erected structure will be doubtful.

Benefits of using cinder blocks

• Big sizes. Cinder blocks are very easy to lay and erection with their help is quite fast;
• Profitability. Apart from affordable price these products, cinder blocks also require much less mortar for laying the wall;
• Durability. Another undoubted quality of the cinder block, which makes it extremely attractive. Buildings erected with it can stand for a very long time;
• fire resistance;
• A variety of filler makes it possible to select the material for your needs.

Disadvantages of using cinder block

• High thermal conductivity. In other words, it can be cold in cinder block houses. But only if you make a mistake with the choice of this material. After all, as we said above, there are many types of cinder block, and among them there are options with low thermal conductivity;
• High sound transmission. Partly solvable the right choice insulating materials;
• Hygroscopicity. The cinder block absorbs water very well, so the walls from it require plaster on both sides. In addition, you should not build such houses in places prone to floods or characterized by a very humid climate;
• Environmental friendliness. When purchasing cinder blocks, you need to ask the seller about the availability of a safety certificate. It's all about the content of sulfur and acid there, which disappears only after a year under open sky. The certificate of environmental safety is given only to such materials;
• For some, the high strength of the cinder block can be not only an advantage, but also a disadvantage, since in this case it becomes not very convenient to lay communications.

How to calculate the amount of cinder block per wall

When compared with a brick, the cinder block immediately stands out for its size. The standard unit of such building material is equal to as many as five bricks. Above, we have given the most popular size (), but there are others that are different from it - 395 * 195 * 195, 390 * 120 * 188 and 400 * 200 * 200. But these options are much less common.

In this regard, there is a simple calculator to help calculate the number of cinder blocks per wall. So, we multiply the width by the length (190X390) and we get the area of ​​\u200b\u200bthe wide face, equal to 0.074 square meters. Dividing the unit by this number, we get that for the construction of one square meter walls we need about 14 blocks. Now it remains only to calculate the total area of ​​\u200b\u200bthe wall, and we will get the number of required blocks. But it is better to take with a margin - about 10 percent more than necessary.

• Since this material gets wet very well, it is better to try to raise the foundation above the ground. As for the base, it must be well insulated;
• The ideal and simplest insulation for cinder block walls is a semi-liquid mortar of cement and sand. We spray such a “fur coat” on the walls with a large brush. After the first layer has dried, it is best to apply the second;
• The appearance of the cinder block is quite unsightly, so you need to take care of outdoor decoration. For this, siding or decorative bricks can be used;
• If you want to achieve environmental friendliness, moisture resistance, as well as high insulating properties, then it is best to use expanded clay concrete. In it, the slag is replaced by expanded clay, which significantly changes the properties of this building material;
• A lot of cinder blocks are made in a handicraft way, since the raw materials for them are cheap, the manufacturing technology is simple, and vibropresses are relatively affordable. It is not possible to check the quality of such products and what they are made of. So, it is best to buy cinder blocks from large sellers.

Conclusion

From all of the above, it is quite obvious that it is not recommended to use a cinder block for the construction of a residential building. But this building material can be a real godsend for those who decide to build certain adjoining buildings without spending a lot of money on it. In this case, you get really economical option construction.
