Inside the constructing materials market, silicate brick has appeared comparatively not too long ago, but has already managed to achieve immense popularity amongst our compatriots. Its technical characteristics permit to erect buildings and structures that meet all modern high quality criteria. And if we consider the material in the standpoint of price tag / good quality, then gas silicate products will certainly take one with the top areas.

What it really is?
If to speak as simply as possible, the gas silicate brick is one on the varieties of porous concrete. At the exit, the material is quite porous, but at the identical time its strength qualities are totally consistent with the parameters of concrete. The main difference is in weight. Gas silicate blocks are significantly less heavy - the parameter reduction is accomplished resulting from the voids inside the pores.
In the 18th century, builders usually added bull or pig blood to concrete and obtained a prototype of modern aerated concrete: when components had been mixed, blood protein entered into a chemical reaction with other substances, and because of this foam appeared, which, when solidified, transformed into a sturdy building material.
One in the most well-known engineers inside the Soviet Union, M. N. Bryushkov, back within the 30s of the last century, noted that when squeezed plants were added to cement named the “soap root”, which grows inside the republics of Central Asia, the mixture right away starts to foam strongly and develop in size. When frozen, the porosity remained, and the strength increased considerably. Even so, the Swedish technologist Albert Erikson played essentially the most considerable role in developing the gas silicate. He designed a one of a kind technologies for the production of material by adding gas-forming chemical elements to cement.
Now, gas silicate bricks are produced from cement with the addition of sand and hydrated lime. Then the mixture is passed through autoclaves and subjected to foaming using the addition of unique magnesium dust and aluminum powder.
The finished substance is poured into types, subjected to drying and hardening, that is accomplished in two primary methods:
in organic circumstances;
in the autoclave below the influence of higher temperature and robust pressure.
Greater blocks are obtained by drying in an autoclave manner. Within this case, they develop into more durable and resistant to external adverse circumstances.
Therefore, it may be seen that the gas silicate block is a rather uncomplicated composition of low-cost and universally sold components, so the material is really useful in housing construction.
Characteristics and composition
The composition of gas silicate material consists of the following elements.
Portland cement of the highest high quality, which can be produced in accordance using the applicable State Requirements. It consists of calcium silicate (its share is at the least 50%), together with tricalcium aluminum (6%).
Regulatory sand. This brand is characterized by a minimum amount of silt and a variety of clay inclusions, the content of which really should be no much more than 2%. Also involves quartz, about 7-8%.
Technical water.
Calcium lime, which is called the "kettle", to create porous concrete requires a composition not reduce than the 3rd grade category. The rate of extinction of such a element is 10-15 minutes, while the percentage of burnout will not exceed 2%. Boiler also consists of oxides of calcium and magnesium, the total share of which reaches 65-75% or additional.
Aluminum powder - is added for increased gas formation, materials like PAP-1 and PAP-2 are used.
Sulfonic C is usually a element connected to surface-active substances.
The composition and qualities from the technologies figure out the properties in the material, amongst which they note both good and adverse.
The positive aspects of gas silicate bricks contain the following characteristics.
Low thermal conductivity. Within the production in the material, the initial mixture is saturated having a big number of bubbles as a result of the content material on the aluminum powder, once they freeze, they're converted into pores, which drastically impacts the thermal conductivity. That is certainly, the additional pores, the better the material retains heat.
Let us clarify with basic examples. When you live inside the northern regions with harsh winters, then a 50 cm thick wall is adequate to keep the heat inside the living space. You can have much more, but as a rule, there is sufficient half-meter barrier.In locations with a warmer climate, the thickness might be 35-40 cm, within this case, even on cool nights, the rooms will sustain a favorable microclimate and cozy atmosphere.
Not much less important feature of aerated concrete is good vapor permeability. When the humidity level inside the room is larger than outdoors the house, then the walls begin to absorb excess moisture from the air and send it outside. When the predicament is reversed, then every thing takes place specifically the opposite: gas silicate bricks absorb moisture in the outdoors and transfer it towards the space, this is in particular true when the heating is turned on, when the air in the heated area becomes also dry.
For residential buildings is crucial fire resistance of your material. The walls of gas silicate can withstand contact together with the flame for about 3 hours, as a rule, this time is adequate to put out the fire, as a result, in case of fire, the chances of saving the house are very significant.
The low weight of bricks also belongs for the undoubted benefits on the material. It can be easy to transport, raise to a height, additionally, the design doesn't generate a big load on the foundation, and this substantially increases the service life of the house.
Gas silicate blocks are released from all-natural components, so the material is environmentally friendly. It is actually rather feasible to use it inside the building of kindergartens and educational institutions, polyclinics, residential areas along with other buildings, exactly where the absence of toxic secretions is of basic significance.
Nicely, a nice addition are going to be superb sound insulation, that is achievable as a result of the exact same porosity of gas silicate.
