Thermal insulation. Energy savings up to 70%.
According to the results of numerous studies of building physics institutes up to 75% of heat loss occurs through the building envelope (walls)!
«3C» concrete with density 400 kg/m³ possesses the termal conductivity less than 0.09 W/mK*℃. It is proved in practice that the use of «3C» concrete in building and construction to reduce heat loss by an average of 2!
This means that considerably less heat energy required for space heating. A cooling using air-conditioning or heating electrical systems require much less power.
For example, a house built by «3C» technology in Kovrovo, Kaliningrad region, according to the calculations of experts, 12 years of service will pay for the construction costs.
Soundproofing. Getting rid of the noise.
Walls and floors made of «3C» concrete possessing sound-insulating properties. You don't need to apply additional materials for sound insulation.
You will forget about the noise from above, from below and from adjacent rooms.
Waterproofing. Getting rid of the floods and leaks.
With proper manufacturing «3C» concrete itself does not pass through the water, keeping a small amount of moisture (8-12%) in direct contact with water.
The quality of life. Comfortable living.
«3C» concrete can increase the level of comfort in the room. «3C» in it's environmental properties is in line with wooden structures.
Material "breathes", adjusting the room humidity. However, unlike wood and other materials, a «3C» concrete does not rot, does not burn and does not rust.
The microclimate in houses built of «3C» concrete close to the microclimate in wooden houses: cool in the heat in them, and in the winter is warm and cozy.
Safety. Caring for the environment and your own health.
«3C» concrete does not have in its structure radioactive, carcinogenic agents, heavy metals, which is confirmed by sanitation service.
«3C» concrete provides high earthquake resistance due to lightness and strength and certified to be used in seismically dangerous zones.
«3C» concrete provides high fire resistance. It is absolutely non-flammable material.
Resilience factors. The longevity of buildings.
«3C» concrete shows resistance to moisture, aging, resistance to microorganisms;
«3C» concrete ensures high freeze-thaw resistance (over 100 cycles), which significantly extend the operation of any building, regardless of the climatic conditions;

During the construction of housing, the use of «3C» concrete is much cheaper than using traditional materials (brick, gas silicate blocks, cinder blocks, heavy concrete, etc.). Due to the fact that the «3C» concrete has excellent heat-insulating properties it does not require additional insulation polystyrene, mineral wool, etc.
This can significantly reduce the cost of building materials and increase the speed of construction. The absence of cold bridges (due to monolithic structure of «3C»), the unique properties of the material, can reduce the cost of housing at the expense of the cost of operation of the heating equipment, reduce energy consumption for heating, etc.
To build the entire house you will need only the «3C» concrete.
