How to build a house of gas blocks with your own hands?

Probably everyone dreams of owning a house. But due to various circumstances, it is often not possible to purchase a private living space. If you can not buy a house, then you can build it. With the new construction technologies, it is now possible to build a house of gas-blocks in a relatively short period of time with our own hands. Such buildings are durable and will last for many years. In this case, the building will not lose its operational characteristics.

The process of construction of aerated concrete blocks is by no means easy or simple. However, if we compare it with a brick or a rounded bar, the amount of effort that will be required is much less. How to make a house of gas blocks with your own hands? A step-by-step instruction will be considered in our article.

Characteristics of the material

Aerated concrete blocks are a relatively new and technological building material. It is designed to create walls in low-rise apartment buildings. Blocks are made of quartz sand, as well as cement with the addition of lime and water. Under pressure and under the influence of high temperatures, bubbles form in this mixture. After the mass has solidified, a block with a porous structure is obtained. This production technology makes it possible to produce a block of large volume. At the same time it will be light and durable.

Material Advantages

Among the advantages are good heat and sound insulation characteristics, resistance to low temperatures, strength, and density. The block is very light - this is an important advantage, as there will be no heavy loads on the foundation. The size of one element is much larger than the standard brick. This greatly speeds up the time spent on construction. By value, a house made of gas blocks, created by its own hands, will be much cheaper than if the building were built of traditional materials. This is due to the relatively low prices for aerated concrete blocks due to the high popularity of this building material. Also among the advantages can be identified high fire safety. The construction of aerated concrete is least likely to be ignited and ignited. If the block has the correct and beautiful shape, and they were laid professionally and neatly, then the wall can not even be trimmed. This will give the building the opportunity to "breathe". Aerated concrete due to pores is distinguished by high rates of vapor permeability.

Preliminary preparation

Before you build a house from a gas block, you need to determine the appropriate location. Then you need to prepare all the necessary documents. This is a design and estimate documentation, which must already be certified in local government. Next, you need to order and conduct geodetic work, install fences, determine the point of the zero horizon and bring all communications.

After all the documentation is prepared and received, you can begin work on the layout of the site. If the enclosure is already installed, lighting should be installed, and scaffolding should be installed.

Acquisition, transportation, storage of gas blocks

It is not difficult to buy this building material. It's enough just to find a suitable manufacturer and place an order along with its delivery directly to the site. But here there are nuances. Not all companies involved in the delivery of building materials are ready to travel to remote locations with bad roads. In this case, you will have to find the transport yourself. For those who decided to start building a house from a gas block (photo examples - in our article), this should not be a big deal.

Often, aerated concrete is supplied on pallets. Blocks are securely packed in polyethylene film. When storing these building materials, excessive moisture can accumulate inside, and damage to the structure is possible. At the construction site, place materials best under a canopy. Unpack is desirable only those that will be used in the work. Pallets can be installed in the form of stacks. But do not allow this installation in more than two rows.

Number of materials for construction

So, when all the project documentation is on hand, it is necessary to determine how many gas blocs are needed per house. Do not buy too much. There are certain difficulties associated with storage. You need to calculate how many cubic meters of materials you need. For example, take a 10 m long by 8 m. You need to calculate the perimeter. This is 10 + 10 + 8 + 8 = 36 m. The height of the wall is 3 m. So, 3 * 36 = 108 m ² . This is the area of all the walls.

Blocks are offered in cubic meters. To calculate how much construction materials are needed to build a house from gas blocks, you need to multiply by 0.3. This will be the thickness of one block. As a result, 32.4 m ^{3 of} materials are needed. This amount for the construction of only the outer walls. Internal walls are calculated in the same way.

Foundation and ground floor

Next, you need to fill the foundation yourself. Houses from the gas block are not heavy, but the surface must withstand the load on the ground. It is possible to fill a concrete slab or use a foundation foundation as a foundation, which is more preferable for small 1-2-storey buildings.
What it is? Tape monolithic foundations - a mixture based on concrete with increased strength characteristics. In addition, the structure can be reinforced with rigid pins made of metal with a diameter of 15 mm. They are stacked in two layers. If the site for construction is in place, where the groundwater level is elevated, or on the soils, then the best solution in this case is the foundation with a monolithic grillage.

Before you start serious work on the arrangement of the foundation, you must carefully clean and maximize the alignment of the place. For a small 1-2-storey house there will be enough foundation 2 m deep. The trench must be along the entire perimeter of the whole future building. It is important to calculate the required amount of concrete. When everything is ready, we fill in the material and after completely freezing we build a house from a gas block.

What to choose for fixing blocks

There are two options for fixing aerated concrete products. This is a special glue or cement mortar. Both options have certain pros and cons.

With the use of glue, you can get the right joints. The masonry will leave very smooth. But in the process of exploitation, the glue will emit into the atmosphere toxins, and at a cost it will be more expensive than the solution. As for cement mortar, the work with it is more laborious, because it will have to follow the flatness of the walls. But in the case of a solution, fixing mistakes will be easier than with glue. Also, if we build a house from a gas block with our own hands on solution, then there are no strict instructions for mixing. Usually, the mixture is made in a ratio of 3 to 1 (parts of sand and cement, respectively). Then water is added, and all this is mixed.

Features of the construction of walls

Aerated concrete blocks have one important feature - they are light. Therefore, the solution or glue will not be squeezed out under the weight of the material and, accordingly, will not leak out of the seams. This greatly speeds up the process of laying the walls. It should be noted that a special tool is required to work with this building material.

For the erection of a bearing wall, it is recommended to use blocks, the size of which is from 375 to 400 mm. If the partition wall is laid, then the width of the product can be no more than 250 mm.

We stack the first row

So, if we build a house from a gas block with our own hands, then it's worth to approach the construction of the first row very responsibly. Before starting work, it is necessary to conduct waterproofing. The first row of experts recommend laying only on a cement-sand mortar. Laying starts from the highest angle of the future house. At the ends of the block there is a groove and a comb, so there is no need to connect the elements with glue. On the first row pull the cord to control the smoothness of the masonry. If there is a need, then the blocks are leveled with a rubber kijan. If in the process of laying a gap is formed, the length of which is less than one block, then a special additional element is made. To implement the nail, use a hacksaw, electric saw and square. The end surface of this additional block should be previously smeared with a solution or glue. The glue, which is necessary for laying blocks of aerated concrete, is selected for thin seams. Consistency of it should resemble sour cream. Apply the mixture with a special tool. After - level it on the surface of the building material with a spatula. The first row is laid, and we further build a house from gas-blocks with our own hands. Then the instruction recommends to wipe all the formed irregularities with a special grater. Further, dirt and dust are removed from the surface of all blocks. This process is repeated after each successive series. It is important that each new row is stacked with a slight displacement of 8-10 cm. Remains of the solution must be removed by the trowel. The second row should be packed about one to two hours after the first. To protect the wall from moisture, the finished areas are covered with a polyethylene film.

Reinforced bridges of aerated concrete are suitable for use only when creating doorways and windows. They are installed using a special wooden device. The thick part of the U-shaped block is located on the outside of the building. In the cavity of the block, a frame is installed from the reinforcement. Then this cavity is filled with fine-grained concrete. When internal walls will be erected, hydro and noise insulation is mandatory. It should also be borne in mind that every second row of the inner wall must be connected to the wall-bearing anchors or staples using a perforated strip.

Any residential house made of gas blocks (made by yourself or with the help of professional builders, does not matter) will undergo various loads during the operation. This is soil sedimentation, winds, temperature changes. To avoid deformations, the masonry should be reinforced. Consider how this is done.

Reinforcement: how to do it. Deformation seams

Strokes are cut, then the resulting grooves are cleaned of dust, and then the reinforcement is laid into these grooves. After everything is poured in solution. To avoid cracks, make expansion joints. Often they are located in places where the gap is changing or the height of the walls. These seams are made between walls, the temperature of which can be different. Also, a deformation seam is needed where the gas blocks will be connected to other materials in unreinforced walls. Seams should then be sealed with polyethylene film, mineral wool. Both outside and inside are subsequently treated with special sealants.

Overlapping and inclined surfaces

As a support for floor slabs, a reinforced belt is used. Joints, which will be obtained between the plates, must be filled with mortar. The outer ends are covered with hammered girders.

As an overlap fit concrete slabs with a lot of voids in them. But there are also analogues from aerated concrete. The latter have high load-carrying capacity, fire resistance and low thermal conductivity. These plates are acceptable only if there is less than 6 m between the bearing walls. This plate must be supported by a distribution reinforced concrete belt. If a house made of aerated concrete is built with your own hands, then you can avoid cold bridges. Windows, roof and foundation are insulated according to standard technologies. As for inclined surfaces and openings with complex shapes, they can easily be made with a saw. This is easily explained by the fact that blocks of aerated concrete are very easy to saw and drill. All drilling holes are drilled with a drill and a special cutter. Shtruborez easily cope with the creation of grooves for wiring.

Roof

The roof for the house from gas blocks can be any - it is possible to make one-, two-pitched, mansard, hip and others. The latter type is the best choice for residential buildings. Regardless of the design, the roof must be completed with hydro-, heat- and vapor-insulating materials. In some cases, when installing a residential attic, additional noise insulation material is mounted. From above the rafters fix the waterproofing. It is much more convenient to do this with the help of long rails. The latter will perform the function of a restraint. Under gibroizoljatsiej between rejkami put a heater. Then the layer of thermal insulation is closed with a vapor barrier film. Dale put the finishing roofing.

Finishing work

The dwelling house from the gas-block by own hands is practically made. It remains to perform the necessary finishing work, to conduct the communications necessary for a comfortable life, to install windows and doors. Work on the facade can be started only when the roofing and eaves are finished. Preliminarily, the surface is leveled with a grater, and the chips are filled with a solution. As a material, you can choose anything. Benefit of the modern market offers a lot of options for textures and colors.

Conclusion

So, we found out how to make a house of gas-blocks with our own hands. A step-by-step instruction will help in carrying out construction work and will save you from gross mistakes.
