Brick, It is usually considered to be a traditional building material, for the construction of the walls of the house.

But today there are such materials that are largely more easier, which have good thermal insulation properties and most importantly, more cheap, to such materials for the construction of walls of the house include cell concretes.

Gas-silicate, gas-concrete, Penosilicate materials for the construction of house walls are one class of building materials - Industrial building materials.

Concretes Cellular, it seems not so long ago that appeared in the construction market, the rapid pace is gaining popularity. Cellic concretes differ one from the other materials used for their manufacture and production method, cellular concrete relate to the group of lightweight building materials for the construction of walls at home.

Foam concrete is a simple cement solution, which adds special surfactants, which cause its foaming, which is performed by a mechanical method. For foaming, the mass of concrete is saturated with air bubbles and a cellular structure occurs. These cell foam concrete cells are completely sealed and saturated with air. The number of such cells and create a foam concrete sound-warm insulating properties and ease. Make foam concrete, it is possible to different density by changing the composition of the mixture for the manufacture of foam concrete - from 400 to 1800 kg / m3. In this case, you can strengthen the strength of foam concrete, but at the same time, heat transfer resistance will decrease.

In the form of foam concrete from the inside, foam concrete reminds - porous chocolate, looks like a simple gray stone. Foam concrete blocks are made by sizes: 600 x 300 x 250 mm and 600 (length) x 300 (height) x 200 (width) mm. Foam concrete blocks are for the construction of partitions inside the house, with a width of from 50 to 600 mm.

By type of application, building materials from cellular concrete can be divided into the following types: structural heat-insulating, thermal insulation and structural. For the construction of supporting structures of buildings, blocks made of cellular concrete with a density of minimum d 500 are used, and for the density tabs of 400.

Mesh concretei won my popular, mainly due to its physical properties. The cellular concrete for the construction of the house walls, has the same heat-insulating properties, as well as wood, from 0.12 to 0.4 W / (M K), can be compared, in the pine insulating properties of 0.14 W / (M-). Building foam concrete materials Lights - this indicator, significantly reduces the foundation.

Foam concrete can be easily processed, it perfectly resists the effects of high temperatures, racks to temperature differences, confusion, durable, environmentally friendly, possesses vapor permeability, has good adhesion. Walls house built from cellular concrete will have many times greater insulation than for example bricks.

Aerated concrete construction materials racks for fire, are not subject to rotting and corrosion, easy to work (they are simply to handle it easy to mill, drill, fine). It has smooth edges, a smooth surface. Gazo concrete building materials possess such high-quality properties as good thermal conductivity, which is higher than that of building materials such as silicate and ceramic materials, excellent indicators of water absorption and vapor permeability. In comparison with the baptoclave foam concrete, 2 times more reliable, with the same density. For the construction of walls of the house, it is enough of one single-scale block of having a thickness of 37.5 cm.

Construction of houses using cellular concrete

The cellular concrete has unique properties that create the opportunity to engage in the construction of houses for the whole year. To perform the construction of the house, using this building material is one pleasure, not expensive, easily and pretty quickly, because one block of cellular concrete replaces a whole bunch of standard bricks (a block with dimensions of 60 x 30 x 20 cm is equal to 16 bricks). This type Building material for the construction of walls are fed by easy processing, a simple knife can be given to any desired shape,

Such products are easy to process using a simple hacksaw, this building material, you can give any shape, so you can build the building of any complexity and shape, create arches and rounded surfaces, and when installing in openings of windows and doors it is easy to choose a quarter. For the construction of houses, cellular concrete is used with a density of 400-500 kg / m3, at which it is excellent, a yachd concrete is combined.

In order to prevent the appearance of cold bridges, cellular concrete is desirable to lay on special glue, and not on cement-sandy solution. When cement-sandy solution is used for wall masonry, water goes into the block and seam due to lack of moisture becomes not reliable enough. To increase the strength of the masonry, it is possible to moisten the blocks before erection of the wall, and the masonry itself is performed on a thick layer of cement-sand mixture, the wall will turn out to be durable, but with this variant of the wall masonry, cold bridges are formed. When using glue, the finished dry mixture, which adds special preparations, which hold water. When using glue masonry from cellular concrete, it turns out to be thermally more homogeneous, and the seam is thinner. To perform masonry of the walls of the house 1 m3, it will take about 40 kg of glue. The resistance of twenty kilograms of glue, fluctuates within twenty US dollars.

Construction of house walls - monolithic construction

There is still an aliens of the construction of a house using cellular concrete, bassoclave (foam concrete), using a monolithic removable formwork, building a house in this way, will require less finance, and will cost 1.5-2 times cheaper. The construction of the house with such a method can be engaged in a tolk formation not lower than +10 ° C and for construction requires a special installation, for the manufacture of foam, it mixes the foam with a cement solution and transports the woven mass, to the construction site of the house.

To build the walls of the form we need, for removable formwork used Fiberboard (wood fibrous plates), but for the construction of walls and partitions, it is also possible to use a non-versatile formwork, which is performed from the fiberboard and bricks, but on the construction of the walls of the house, with the use of beaming applause, will be required more money. It is possible to make a formwork by construction, from two strand of brick walls and pour a foam concrete mix between them. Another method of building a formwork, you can build a wall of bricks only from the outside, and on the inside, consolidate plasterboard plates or fiberboard. DVP or GLK, leaving inside the foam concrete surface, you can then dismantle. In the future, you can proceed to finishing the walls, while sticking the tiles, staining ...

When building walls of the brick house, they breathe, as natural natural materials are used for the manufacture of bricks. The brick has excellent sound and thermal insulation properties, it is durable and resistant to biological and atmospheric impacts building material. On environmental properties, brick is ahead of only a tree, with bricks easy to work, it is perfectly combined with construction materials from metal, concrete, stone, glass. When building walls of the house from full ceramic brick, it takes no little time and labor, it is necessary to play the heat insulation of the walls, the large number of cement mortar is due to the traditional silicate brick, which mainly consists of water, lime and sand, then it is not very Environmentally friendly, absorbs moisture and it is pretty heavy building material.

To eliminate the above flaws, during the construction of the walls of the house, you can use the paired ceramic blocks, which are a little bit more expensive bricks, but much better. Brick parameters, determine its technologically correct use.

The ceramic brick size is: in the form of blocks with dimensions of 25 x 12 x 25 cm and more, single 25x12x6.5 cm, one-and-a-half - 25 x 12 x 8.8 mm., Double - 25 x 12 x 25 cm.Mark ceramic brick is indicated by the letter M (M 100, M 125), which this letter means the strength of the brick. The digit after the letter, denotes the pressure that can withstand, not destroying, 1 cm2 of the material surface. The weight of the brick depends on the brand, above the brand, also the brick.

In percent, it is characterized by a water-absorbing ability of bricks, absorb moisture. For the construction of outdoor walls of the house, it is desirable to use brick with low water absorbing properties. The frost resistance of the brick is indicated by the letter F (F 25, F 50). The coefficient of thermal conductivity of the brick depends on the structure and density. The thermal conductivity coefficient for the brick of the facial ceramic should be-0.36-0.5 W / (M K), the invoked ceramic blocks - 0.09-0.18 W / (M-K), clinker brick 0.8 W / ( M-K). The thickness of the wall depends on the magnitude than it is higher, the thicker to preserve heat, there must be a wall of the house.

What material to choose

Choosing today building material for the construction of walls of the house, between brick and cellular concrete, you need to carefully treat their aesthetic, energy-eyebrope and economic properties. Today, thanks to the development of technologies, the aesthetic and exploitation of the bricks increased greatly. You can build walls of bricks by the method of lightweight and solid masonry. To build a wall by solid masonry, to conserve heat saving, the wall should be warm or have a thickness of at least 1.9 m. In cellular concrete, thermal conductivity is four times less than that of the brick, therefore, during the construction of walls of them, the thickness of the enclosing heat-insulating layers may Be no more than 400-500 mm. Buing the walls of the house, using cellular concrete, you will save on heating 30-40%, without spending money on thermal insulation materials. When building walls of houses from cellular concrete, you also save not only money, but also time.

Construction of walls at home - microclimate

The microclimate in the house built from cellular concrete, very similar to the microclimate in a wooden house. In the house built from cellular concrete, the fungus does not appear and mold, because this building material has a higher vapor permeability brick and can adjust the humidity of the air indoor. Capillary concrete and brick have a capillary structure, these building materials absorb water from air and soil, but since the walls of houses constructed from these materials are subject to finishing that enhances them from external atmospheric impacts, and high water absorption requirements are presented.

It is not advisable to separate the walls of the house built from cellular concrete clinker or luminous bricks for facades, these building materials have a big density and low vapor permeability. It is necessary between finishing from a brick and carrier wall, it must be a gap. The finish of the facade of the house, which is completed close, not the mercy of going out of the premises of the house, as a result, dampness is formed on the walls inside the house.

Construction of walls of the house of cellular concrete - foundation

When building a foundation for a house, built from cellular concrete, you need to pay special attention to strength. Mesh concrete on a break, not very durable. For example, for houses built of brick or wood allowed small basement of the foundation, then with such movements, the house built from cellular concrete will give a crack.
