Reinforcement of aerated concrete blocks. Aerated concrete blocks: dimensions and price

Many private builders are wondering why it is necessary to reinforce aerated concrete blocks.

Necessity of reinforcement

First of all, it is necessary to do this in order to make the walls more durable, if such manipulations are carried out, cracks do not appear, in addition, the building will have a longer service life. If the conditions for reinforcing masonry in the construction documentation are not specified, then the location of the reinforcement belt should be determined independently.

In what cases is reinforced aerated concrete masonry

Reinforcement of aerated concrete blocks, as a rule, is done during the laying of blind walls, overlappings, support zones of bridges. Reinforcement of the walls should be done also when the distance between the floors will need to provide a distance of more than 3 meters. In addition, it is necessary to reinforce the sections of the window sills. In this case, the reinforcement must be located in the grooves, which must be previously prepared, while the elements are fixed with a special glue. In order to ensure better sealing and fastening of the reinforcement, a solution based on cement and sand should be used. When building buildings from aerocrete blocks, the reinforcement is made in well prepared stitches.

Features of the reinforcement

Reinforcement of aerated concrete blocks must be made in strobes. In order to prepare them, you need to use a technology that involves retreating from the edge of the block 60 millimeters. On the perimeter of the bars, the fittings must be welded by contact or gas welding.

The temperature range from 5 to 25 degrees is considered the most suitable temperature regime, when reinforcement is to be performed. If the temperature is higher, the blocks must first be moistened with water.

Preparation of aerocrete masonry before reinforcement

Reinforcement of aerated concrete blocks will not be possible if you do not prepare some materials and tools, among them you can distinguish: gon, shtoborez, hand saw, building level, mixer, building hair dryer, glue composition or mortar. If there is a desire, then instead of the reinforcement it is possible to apply the reinforcing cage, which is made of galvanized strips.

Features of reinforcement

The aerated concrete blocks, the sizes and the price of which are indicated below, must be reinforced by a certain technology. First you need to prepare the rods of the armature, the material itself, which must be stored under the film. Unpacking the pallets is not recommended, since if the aerated concrete is exposed to water for a long time, it may become unusable. If in the process of work it is intended to use standard aerated concrete products, the dimensions of which are 600 x 300 x 200 mm, then the consumption per 1 cubic meter will be 28 pieces.

The first row of gas units must be laid on the solution. In the process of work, it is necessary to check the leveling of the masonry with the help of a building level, since this will determine the consistency of all subsequent rows. Base and masonry should be separated by a layer of insulation.

Reinforcement of walls from aerocrete blocks is accompanied by stacking at the corners of the slats, which will determine the height of the masonry. To do this, pull the rope, which will control the uniformity of the arrangement of blocks. Masonry should not only be reinforced, but also sealed, for this it is necessary to properly prepare the adhesive composition, which must be homogeneous. Before use, it must be thoroughly mixed. Consumption of adhesive composition will be about 5-10 kilograms per 1 cubic meter. When using a solution, its consumption will be approximately twice as large. Correct the laying it is necessary, using a rubber kijanku. If the block does not match the size, then it can be sawn using a hand saw. In order to ensure a right angle, you need to use a square.

Recommendations of a specialist

Reinforcement of masonry from gas-concrete blocks is made by the method of laying the reinforcement in every fourth row. In order to make shtroby, you need to use an electric shtroborez, which is sometimes replaced with a hand tool. If the thickness of the walls exceeds 400 mm, then it is necessary to make two shtroby, located in parallel with respect to each other. Before you put the valve, you need to remove all the dust from the formed shtrob using an electric building hair dryer. After the surface of the strob can be well moistened and filled with glue up to half the depth. The rods must be well moistened, and then laid. Once the reinforcement has been laid, it is necessary to add the glue and coat the block surface with a solution. The base must be leveled with a spatula. The remaining series should be reinforced by the same technology. During the laying of blocks, vertical seams will appear, from which it will be necessary to get rid of the method of filling the solution. Particular attention should be paid to the cutting site, which is formed after the assembly of the cut block.

Final work

After reinforcement of aerated concrete blocks with reinforcement is completed, the walls can be ennobled with brick, plaster, lining or siding, ceramic or steel sheets can be used. If you want to use a brick as the lining, then between it and aerated concrete you need to leave a small gap. It is worth remembering that the house, which is built of aerated concrete blocks, will be subjected to loads that can cause deformation of the building. Factors such as soil precipitation, changing weather conditions can cause cracks on the walls. When comparing a gas block and reinforcing bar, the first has insignificant resistance to deformation phenomena and bends, while the reinforcement is not subject to this, which should be taken into account when constructing objects using aerated concrete. Aerated concrete, in which there is an armature, does not affect the bearing capacity of the wall, which is beneficial for construction. In order to protect aerated concrete walls from the occurrence of cracks, you can use not only the reinforcement, but also the grid, as well as fiberglass. If a long wall is supposed to be erected during the construction, the reinforcement must be made with the help of rods, not the grid.

Dimensions and prices of blocks

The production of aerated concrete blocks is carried out in accordance with GOST, before purchase you must necessarily study the dimensions of products, this will allow to produce construction works with greater economy. Thus, blocks without a comb can have a length of 600 mm, while their width and height are 100 and 250 mm respectively. The price of such a unit per cubic meter will be equal to 3,400 rubles. Blocks can be made and with a groove, their size at the same time is 600 x 200 x 250 mm. The price of such a block will remain the same. The production of aerated concrete blocks is carried out both with the presence of not only the ridge, but also the grip, while the size of such a block will be 600 x 400 x 250 mm, the price will remain the same as indicated above.

The blocks are aerated concrete, the size and price of which you are aware, are now widely used in construction.
