How to put gas blocks: stages of work and features

If you study the technology that tells how to put a gas block, you can build a garage, a bathhouse or a house on your own without the help of specialists, which will save on expensive services. It is important to learn about the method of work, as well as what kind of solution for mounting products should be used.

Preparation of tools

Before laying aerated concrete it will be necessary to prepare a set of certain tools, among them:

  • building level;
  • Rubber mallet;
  • plane;
  • Armature;
  • Marking cord;
  • Hacksaw with large teeth for aerated concrete;
  • Electric or manual shtoborez;
  • A narrow brush for removing dust from the strobes.

Once the above tools are ready, you can start laying the material.

Preparation of cement slurry

Many novice masters are pondering the question of whether it is possible to put a gas block on a solution. Experts, responding, emphasize that the cement-sand mortar is used only for the first row of blocks, the strength, reliability and durability of the future structure will depend on how exactly the products are located in it.

For the preparation of cement mortar you will need:

  • sand;
  • water;
  • shovel;
  • cement;
  • Soap solution.

One shovel of cement is poured into the tank, to which should be added three shovels of sand. Ingredients are mixed in a dry form, and afterwards a bucket of water is added to them. When mixing the solution, use one drop of dishwashing detergent, which will help to eliminate the effect of settling the mixture on the bottom. Among other things, kneading will make much easier. The amount of water can vary depending on the initial density of the solution. It should be mixed to a homogeneous mass, only so you will ensure its normal distribution.

Laying blocks in the first row

Before you put gas blocks on your hands, you should find out that the quality of further work will depend on the correct placement of products in the first row. Bricks should ideally be matched to each other, otherwise the wall will have an irregular geometry. For the reason that aerated concrete is prone to excessive absorption of moisture, it is necessary to exclude water from the basement. For this, a waterproofing material is laid on the basis of the house on a bitumen base, and masonry work can be started on its surface.

The very first blocks are laid on the corners of the basement, the first of which is set in the highest place among all the others. This point can be determined using a construction level. The first row is laid on the mortar, the thickness of the seam should be equal to two centimeters. The correctness of the location of the blocks should be checked with the help of a building level, measurements should be carried out in all planes. Before putting the gas-block, in the interval between the four products set in the corners, it is necessary to pull the marking cord, and it will determine the location of other products. If the length of the wall was more than 10 m, then in the central part should be placed one more block, which will act as an additional beacon and will not allow the rope to sag.

Methods of work

In order to adjust the bricks to each other, you should use a rubber mallet, on the surface of the products you need to gently tap. Once the beacons were perfectly aligned, you can proceed to fill the series. It also happens that on the length of the wall it is impossible to arrange only one-piece products, for this reason it is necessary to use additional bricks. Blocks are cut to the required size using a hacksaw with large teeth. The internal load-bearing walls are made of blocks of the same thickness as the outer ones. Work on their formation should be carried out simultaneously. In the outer brick, you need to cut a quarter and insert the inner block into it, squeezing the space with the adhesive solution.

In the process of laying, it is necessary to provide a bandaging along the outer and inner walls. The offset between two adjacent rows should be 8 cm or more. In those places where it is supposed to erect partitions, flexible walls should be laid in bearing walls. They are fixed in products with the help of nails, as an alternative solution is used to seal into the seam.

Advice from a specialist

If you are faced with the question of how to put a gas block, then after completing the first row, you will have to wait 2 hours, which will go to grasp the solution. The subsequent rows are laid on the glutinous mixture. The laid row must be wiped with a plane, so that the next rows fall as flat as possible. This applies to the side surfaces, which makes it easier to plaster the walls. After grinding from the base, the formed dust is removed, it is useful for filling technological holes, for example, grooves for carrying. If necessary, the formed dust is mixed with the masonry mortar.

For reference

Before you put the gas block, prepare a special carriage, with which it will be convenient to apply glue to the surface. On the lateral bases, the glue is distributed with a trowel, bucket or notched trowel.

Adhesive or solution

If you are faced with the question of how to properly place gas blocks, then you should think about choosing between a solution and a glue mixture. The advantage of the latter is that it can be used to form twice as thin stitches. This helps to save on the material and justifies the use of the formulation. In order to ensure the normal quality of the masonry, there will be enough seam, the thickness of which varies from 2 to 5 mm.

Features of reinforcement

How to put the first row of the gas block correctly, has been described in detail above, now it's time to get acquainted with the technology of reinforcement of the main masonry. To do this, every three or four rows should be made in the products of the grooves, which should be located on the top of the block. They are filled with glue, and then are supplemented with rods of reinforcement. In this case, the metal elements must be completely immersed in the mixture. If the laying of the bearing wall is carried out, the reinforcement is made in two rows. When you are faced with the task of how to correctly place gas blocks on glue, you should familiarize yourself with how the window openings are reinforced. For them, two rows of grooves are made which extend beyond the window by 50 cm.

Reinforcement of partitions

For the redevelopment of the building, it is necessary to use partitions, which can also be made of aerated concrete blocks. When tying the partition to the wall, it is necessary to use shtroby, in which the projections of the blocks are directed. In order to link several partitions to each other, you must apply the quarter-block sawing method. The partition must also assume the need for reinforcement. However, its laying is carried out in one row, and the elements are removed from each other by three or four rows. The installation of partitions must be accompanied by the installation of a reliable base, among other things, it is important to take care of the presence of waterproofing.

Nuances of reinforcement

If you are thinking about how to put gas blocks on glue, you should learn more about the reinforcement technique. If you ignore this stage, then the walls of the house will disperse light cracks. In addition to the horizontal, there is also a vertical reinforcement, which is not considered mandatory. When settling two slings should be retreated from the edge of the laying of 60 mm. As the reinforcement, steel corrugated rods with a diameter of 8 mm should be used. In order to tie two rods, they are overlapped, the width of which is 300 mm. At the corners of the stems should be rounded. Once the element is inside the strobes, excess glue should be removed.


Many novice masters are thinking how to put walls from a gas block. There are many nuances of carrying out works, one of them is the possibility of using manual shroud cutting. With its help it is quite difficult to equip the strobes, and in order to make them even, you should lay a straight board on a row of blocks and strengthen it with nails. On it and will be made strob.

Features of vertical reinforcement

Another way to strengthen the walls of the house from aerated concrete is vertical reinforcement. It is performed in the corners and some walls of the building. This technology allows you to connect the base of the building with the upper monolithic belt. As advantages it is possible to allocate additional stability of construction against a wind, however there are also minuses, one of which is expressed in creation of bridges of a cold.


Despite the fact that aerated concrete is considered to be a fairly light material, and construction with its use can be carried out independently, transportation can not be carried out without the use of special equipment. The weight of one block can reach 26 kg, while the mass of products in a pallet is equal to a ton.
