If you study the technology, which tells how to put the gas block, you can build a garage, a bathhouse or a house yourself without the help of specialists, which will save on expensive services. It is important to learn about the methodology of the work, as well as about which solution for mounting products should be used.
Tool preparation
Before laying aerated concrete, it will be necessary to prepare a set of specific tools, among them:
- building level;
- rubber mallet;
- plane;
- fittings;
- marking cord;
- hacksaw with large teeth for aerated concrete;
- electric or manual chipper;
- narrow brush to remove dust from the strobes.
Once the above tools are ready, you can start laying the material.
Cement slurry preparation
Many novice masters think about the question of whether it is possible to put a gas block on a solution. Experts, responding, emphasize that cement-sand mortar is used only for the first row of blocks, the strength, reliability and durability of the future design will depend on how smoothly the products are located in it.
To prepare the cement mortar you will need:
- sand;
- water;
- shovel;
- cement;
- soap solution.
One shovel of cement is poured into the tank, to which three shovels of sand should be added. The ingredients are mixed dry, and then a bucket of water is added to them. When mixing the solution, one drop of dishwashing detergent should be used, which will help to eliminate the effect of the mixture settling to the bottom. Among other things, kneading will be much easier. The amount of water may vary depending on the initial density of the solution. It should be mixed to a homogeneous mass, only in this way you will ensure its normal distribution.
Stacking blocks in the front row
Before you put gas blocks with your own hands, you should find out that the quality of further work will depend on the correct location of the products in the first row. Bricks should ideally fit together, otherwise the wall will have the wrong geometry. For the reason that aerated concrete is prone to excessive absorption of moisture, water suction from the foundation should be excluded. To do this, on the base of the house, a waterproofing material on a bitumen basis is lined, on its surface, masonry work can begin.
The very first blocks are laid in the corners of the foundation, the first of them is installed in the highest place of all the others. This point can be determined using a building level. The first row is laid on the solution, the thickness of the seam should be equal to two centimeters. The correct location of the blocks should be checked using the building level, measurements should be carried out in all planes. Before laying the gas block, in the gap between the four products set at the corners, it is necessary to pull the marking cord, it will begin to determine the location of other products. If the wall length turned out to be more than 10 m, then in the central part one more block should be placed, which will act as an additional beacon and will not allow the rope to sag.
Methodology
In order to fit the bricks to each other, you should use a rubber mallet, on the surface of the products you need to gently tap. Once the lighthouses have been perfectly aligned, you can begin to fill the row. It also happens that along the length of the wall it is not possible to arrange only whole products, for this reason it is necessary to use additional bricks. Blocks are trimmed to the required size using a large-tooth hacksaw. Internal load-bearing walls are made of blocks of the same thickness as the external. Work on their formation should be carried out simultaneously. In the outer brick, you need to cut a quarter and insert the internal block into it, smearing the space with an adhesive solution.
During installation, dressing should be ensured along the external and internal walls. The offset between two adjacent rows should be 8 cm or more. In those places where it is supposed to build partitions, flexible connections should be laid in the bearing walls. They are fixed in the products with the help of nails, as an alternative solution walled in the seam is used.
Specialist advice
If you have a question about how to lay a gas block, then after the completion of the first row you will have to wait 2 hours, which will be spent on setting the solution. Subsequent rows are laid on the adhesive mixture. The stacked row must be wiped with a planer so that subsequent rows lie as evenly as possible. This also applies to the side surfaces, which makes it easier to plaster the walls. After grinding, the dust formed is removed from the base; it is useful for filling technological holes, for example, grooves for carrying. If necessary, fill the resulting dust is mixed with masonry mortar.
For reference
Before putting the gas block, prepare a special carriage, with which it will be convenient to apply glue to the surface. The glue is distributed on the lateral bases using a trowel, bucket or notched trowel.
Glue 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 an adhesive mixture. The advantage of the latter is that it can be used to form twice as thin seams. This helps to save on material and justifies the use of the composition. In order to ensure the normal quality of the masonry, a seam will be sufficient, the thickness of which varies from 2 to 5 mm.
Reinforcement Features
How to correctly lay the first row of the gas block was described in detail above, now it's the turn to get acquainted with the technology of reinforcing the main masonry. To do this, every three to four rows should be grooved in the products, which should be located on the upper edge of the block. They are filled with glue, and then supplemented with reinforcing bars. In this case, metal elements must be completely immersed in the mixture. If the laying of the bearing wall is carried out, then the reinforcement is made in two rows. When you are faced with the problem of how to properly place gas blocks on glue, you should familiarize yourself with how window openings are reinforced. Two rows of grooves are made for them, which protrude 50 cm beyond the window.
Partition reinforcement
For redevelopment of the building, partitions should be used, which can also be created from aerated concrete blocks. When tying the partition to the wall, it is necessary to use the strobes into which the ledges of the blocks are directed. In order to connect several partitions with each other, the method of cutting a quarter of the block should be applied. The partition should also assume the need for reinforcement. However, at the same time, its laying is carried out in one row, and the elements are removed from each other in three to four rows. The installation of partitions should be accompanied by a reliable foundation; among other things, it is important to take care of the presence of waterproofing.
Reinforcement Nuances
If you are thinking about how to put gas blocks on glue, you should familiarize yourself with the reinforcement methodology in more detail. If this stage is neglected, then light cracks will spread along the walls of the house. In addition to horizontal, there is also vertical reinforcement, which is not considered mandatory. When arranging two shtrob, it is necessary to retreat from the edge of the masonry 60 mm. As reinforcement, steel corrugated rods with a diameter of 8 mm should be used. In order to tie the two rods, they are overlapped, the width of which is 300 mm. At the corners, the strobes should have a rounded appearance. As soon as the element is inside the strobes, excess glue should be removed.
Tip
Many novice masters think about how to lay walls from a gas block. There are many nuances of work, one of them is the possibility of using a manual chipper. With its help it’s quite difficult to arrange the strobes, and in order to get them even, you should lay a straight board on a number of blocks and strengthen it with nails. A strobah will be made along it.
Features of vertical reinforcement
Another way to strengthen the walls of the house from aerated concrete is vertical reinforcement. It runs 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. The advantages include the additional stability of the building against the wind, but there are also disadvantages, one of which is expressed in the creation of cold bridges.
Conclusion
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 cannot be carried out without the involvement 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.
