In the developing supplies market place, silicate brick has appeared relatively not too long ago, but has already managed to acquire immense recognition among our compatriots. Its technical characteristics permit to erect buildings and structures that meet all modern high quality criteria. And if we think about the material from the standpoint of price / high quality, then gas silicate products will surely take one of your top locations.
What it is actually?
If to speak as simply as possible, the gas silicate brick is one of your varieties of porous concrete. At the exit, the material is fairly porous, but at the similar time its strength traits are fully constant using the parameters of concrete. The main distinction is in weight. Gas silicate blocks are less heavy - the parameter reduction is accomplished because of the voids inside the pores.
Inside the 18th century, builders frequently 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 tough developing material.
One on the most well-known engineers within the Soviet Union, M. N. Bryushkov, back in the 30s on the final century, noted that when squeezed plants were added to cement called the “soap root”, which grows inside the republics of Central Asia, the mixture promptly begins to foam strongly and develop in size. When frozen, the porosity remained, and also the strength increased drastically. Having said that, the Swedish technologist Albert Erikson played the most substantial role in producing the gas silicate. He created a special technologies for the production of material by adding gas-forming chemical elements to cement.
These days, gas silicate bricks are created from cement with the addition of sand and hydrated lime. Then the mixture is passed by means of autoclaves and subjected to foaming with the addition of special magnesium dust and aluminum powder.
The completed substance is poured into forms, subjected to drying and hardening, which can be accomplished in two most important approaches:
in organic situations;
within the autoclave beneath the influence of high temperature and robust pressure.
Much better blocks are obtained by drying in an autoclave manner. In this case, they come to be extra tough and resistant to external adverse circumstances.
Thus, it may be seen that the gas silicate block can be a rather uncomplicated composition of cheap and universally sold elements, so the material is pretty valuable in housing construction.
Characteristics and composition
The composition of gas silicate material contains the following components.
Portland cement of your highest excellent, that is made in accordance using the applicable State Requirements. It consists of calcium silicate (its share is at least 50%), along with tricalcium aluminum (6%).
Regulatory sand. This brand is characterized by a minimum amount of silt and many clay inclusions, the content of which needs to be no extra than 2%. Also contains quartz, about 7-8%.
Technical water.
Calcium lime, which can be named the "kettle", to create porous concrete needs a composition not reduce than the 3rd grade category. The price of extinction of such a element is 10-15 minutes, though the percentage of burnout doesn't exceed 2%. Boiler also consists of oxides of calcium and magnesium, the total share of which reaches 65-75% or much more.
Aluminum powder - is added for increased gas formation, materials like PAP-1 and PAP-2 are used.
Sulfonic C can be a component associated to surface-active substances.
The composition and traits in the technology decide the properties with the material, among which they note each positive and unfavorable.
The positive aspects of gas silicate bricks contain the following characteristics.
Low thermal conductivity. Inside the production in the material, the initial mixture is saturated with a massive number of bubbles because of the content of your aluminum powder, once they freeze, they are converted into pores, which significantly impacts the thermal conductivity. That may be, the additional pores, the improved the material retains heat.
Let us explain with easy examples. In the event you live in the northern regions with harsh winters, then a 50 cm thick wall is sufficient to keep the heat inside the living space. You can have much more, but as a rule, there is certainly adequate half-meter barrier.In places having a warmer climate, the thickness is usually 35-40 cm, in this case, even on cool nights, the rooms will preserve a favorable microclimate and cozy atmosphere.
Not significantly less critical function of aerated concrete is excellent vapor permeability. In the event the humidity level inside the area is higher than outdoors the house, then the walls commence to absorb excess moisture in the air and send it outside. In the event the predicament is reversed, then every little thing takes place specifically the opposite: gas silicate bricks absorb moisture from the outside and transfer it for the space, this really is specially true when the heating is turned on, when the air within the heated area becomes too dry.
For residential buildings is important fire resistance in the material. The walls of gas silicate can withstand contact together with the flame for about 3 hours, as a rule, this time is sufficient to put out the fire, consequently, in case of fire, the chances of saving the house are quite huge.
The low weight of bricks also belongs towards the undoubted advantages from the material. It really is easy to transport, raise to a height, furthermore, the design will not make a large load on the foundation, and this considerably increases the service life in the house.
Gas silicate blocks are released from organic components, so the material is environmentally friendly. It is quite achievable to make use of it in the construction of kindergartens and educational institutions, polyclinics, residential locations and other buildings, where the absence of toxic secretions is of basic importance.
Well, a nice addition will probably be outstanding sound insulation, which is feasible on account of the same porosity of gas silicate.
