Dreaming of your own home, which will live in your household?Then you should know about the new approach to the construction.It is about the construction of the house of aerated concrete.This home will serve you for many years and did not lose their initial performance.Consider how to make the house of aerated concrete with their hands.
As for aerated concrete, it is a relatively new material used for walls of low-rise houses.House of aerated concrete for more than one decade and retains heat and sound insulation characteristics, frost resistance, strength and density.At the same time the cost of aerated concrete is relatively low, which is why in recent years aerated concrete blocks are particularly popular.
Aerated concrete blocks made of silica sand and cement with admixtures of water and lime.Under the influence of this pressure and temperature the mixture takes its active saturation bubbles.Thus, concrete during hardening, a porous structure.This technology makes it possible to increase the amount of material and to ensure its lightness, durability and other positive properties mentioned above.
Site preparation for construction.Purchase and storage of materials
Once you get all the design and estimate documentation, you can safely start the layout of the construction site.At this stage, you should take care of installing the fence.Then you can carry out installation of lighting and prepare scaffolding.In addition, it is important to invite the surveyors that they had a special measurements, which will help them to determine the position of the axes of your future home and the zero horizon.Then move the external communication.
very important that during transport the concrete blocks were packaged in airtight film because moisture can destroy the material already at this stage.In addition, the units should be carefully strengthened during transportation.This event will help to prevent possible mechanical damage.
Construction of a solid foundation and basement
Foundation for the aerated
basis of each house is sturdy and solid foundation.It must withstand a load on the ground foundation.Before starting the construction of the walls, it is important to lay a solid foundation.You can pour a concrete slab or build a solid foundation tape.
In fact, the solid foundation - a concrete with a high level of strength is further reinforced with rigid pins having a diameter of about 1.5 cm. The valves are placed in 2 layers.If your land is located on the site with a high level of soil water or heaving soils, the best solution would be the construction of an unburied slab foundation.Also allowed the construction of pile foundation with a monolithic grillage.
Before starting work on the arrangement of the heavy foundation should be cleaned and leveled the place for him.If you build a single or two-storey house, you should build a solid foundation depth of about 2 m and a width of 40 cm. The pit should be dug around the perimeter of the future house.It is important to calculate the volume of concrete.Now you can begin pouring the foundation.After he was captured and hardens, you can start the construction process on the arrangement of the cap.
choice of material for bonding concrete blocks.Glue or solution?
adhesive or mortar
for fixing blocks, you can use adhesive or mortar.Each of these materials has both certain advantages and disadvantages.Using the glue joints obtained ideal goes exactly masonry walls.However, during operation of the glue releases toxins, and it costs more expensive solution.
solution also consists of sand, cement and water.Of course, to work with him a little harder, because I always have to measure the evenness of the walls.However, to correct irregularities on masonry solution much easier than with an adhesive.No strict proportions when mixing the solution, usually wizards make the ratio of 3: 1 sand and cement.To this dry mixture was added water and stirred.If the solution is very fluid, then it is added to the sand in the opposite case - the water.If the solution does not leak the trowel between the teeth and hardens, then you did it right consistency.
peculiarity of concrete blocks is their ease, allowing bundling solution is not squeezed out, and, therefore, does not arise from the seams.This allows you to quickly lay out the wall.For the construction of the supporting walls should use the blocks having a size of 375-400 mm.As for the interior partitions, their dimensions may not exceed 250 mm.To work with gas concretes used specifically designed for this tool.
walls of aerated concrete
a laying of the first row of aerated concrete should be given special attention.Before you begin the process required to perform waterproofing.The first row should be laid on a cement-sand mortar.Laying begin with the highest corner of the house.The ends of blocks are tongue and groove, so they do not need to be connected with glue.In the first row of wall pull the cord and control the evenness of masonry level.If you want to smooth out the first row of blocks of rubber mallet.
When laying the first row of the wall you have a gap having a length less than the unit it will be necessary to do so to speak, finishing accessories unit.To-sawing, use an electric saw or a hacksaw ordinary and square.End surface of the pre-final assembly of concrete blocks promazhte adhesive or mortar.
After the laying of the first row is completed, powertrowel all irregularities, using a grater.Then, remove the block dust and dirt.The process should be repeated after laying each subsequent series.It is important to fit the series with an offset to the previous ratio of approximately 8-10 cm. Remains of glue or the solution is removed with a trowel.Laying a second row of blocks can be started only after one or two hours after the first was laid.To protect the walls from moisture areas cover film made of polyethylene.
reinforced aerated concrete bridge only apply to window and door openings.They are mounted with a special wooden props.That part of the U-shaped block, which is thicker, must be disposed outside the home, and from this side should be put warming layer, for example, mineral wool.They need to install cavity reinforcement cage consisting of five or six rows.And then it should be fine concrete pour.Concrete must be sealed, and then leveled.

During the construction of internal walls must be made hydro and noise insulation.In addition, it should be noted that each second row must communicate with the supporting wall anchors or staples, using galvanized perfopolosy.
Each building constructed during the operation is subject to a variety of loads, among which stand out, deposition of soil, wind and temperature fluctuations.To avoid deformation of aerated concrete masonry reinforced.
How to do it?Cut Grooves, clean indentations from dust, put the valve, and then fully apply the solution.
avoid cracking also use expansion joints.They are usually located in places where there is a change in the thickness or height of the walls.Expansion joints are made between the walls, having different temperatures, with compound aerated with other materials in long unreinforced walls etc.Such joints compacted polyethylene foam and mineral wool, the inside and outside is treated with a special sealant
Construction of floors and inclined surfaces
Installation of aerated concrete slabs
Backboard slabs should be based on a ring-reinforced belt.The joints that are formed between the floor slabs should complete solution.And outside of the ends must be closed clumsy blocks.
to overlap, you can use either hollow-core concrete slabs or aerated concrete analogues.Aerated concrete slabs have a high load capacity, low thermal conductivity, high fire resistance.The use of hollow-core concrete slabs is acceptable only if the distance between the load-bearing walls is less than or even less than 6 m. This kind of plate should be based on the distribution belt, made of reinforced concrete.

With proper construction of the house of aerated concrete, you can avoid the so-called cold bridges where there are often large heat loss.As for the windows, foundation and roof, the insulation of their place in the standard manner.
inclined surfaces and openings that have complex shapes, you can manually cut ordinary saw.This is due to the fact that aerated concrete is easy to cut and drill.Even the mounting holes can be cut with a drill with a special milling cutter.The grooves for the wiring of electricity executed wall chaser.
Lining aerated concrete brick scheme
house, built of concrete blocks should be plastered both inside and out.However, you can only use a special type of plaster designed for the aerated concrete.This approach will help you to protect the wall from damage.Make sure before starting the level the surface float and chipped fill solution.
facade decoration can begin only after having been installed and roof eaves above the entrance and held the device blind area around the building.Previously should level the surface of the facade float and chips and fill the gap solution.If you decide to facing bricks, it is recommended to make it to the gap.For this purpose, perfect vibrocompressed brick.The abundance of different colors and textured surfaces will allow you to make the house unique.

Facing a wall you can attach a simple band or anchor, Z-anchor.
