China Ecotrend Autoclaved Aerated Concrete AAC Block for Low Cost Construction, Find details about China Lightweight AAC Internal Wall Block, Autoclaved Aerated Concrete Block Internal Wall from Ecotrend Autoclaved Aerated Concrete AAC Block for Low Cost Construction
Autoclaved aerated concrete (shorted as AAC) block is a kind of lightweight precast concrete block, it is made of cement, lime,fly ash (or silica sand) as the main raw materials, and aluminum powder as the air-entraining agent. It is a new type of building material with superior performance, which is produced in the condition of high temperature, high pressure and steam curing.
Distinctive Advantages:
(1) Sound insulation:
Ecotrend AAC blocks have a large number of micro-holes. Due to the thickness and surface treatment of the wall, the noise can be reduced by 30-50 decibels. For example, the AAC block wall with a thickness of 100mm and double-sided putty can reduce the noise by 40.8 decibels.
(2) Fire resistance:
Ecotrend AAC blocks are inorganic substances, will not burn, and the porous structure of AAC has excellent fire resistance, harmful gases will not be produced at high temperatures, thermal conductivity is low, heat migration is slow, experiments show that the fire resistance limit of 100mm thick AAC wall is more than 4 hours, it is a class A fireproof material and is widely used in firewall engineering.
(3) Impermeable and moisture-proof:
Ecotrend AAC blocks contain independent, closed bubbles and micro-holes, generally 1~2mm in diameter, which can effectively organize the diffusion of water molecules and absorb water and release moisture. When ordinary external wall painting materials are used, the impermeability of the AAC wall is 80% higher than that of clay bricks, which can greatly reduce the humidity inside the building and help prevent condensation and mildew.
(4) Non-toxic:
There are no non-toxic gases or other toxic substances in AAC blocks, and no harmful gases will be produced at high temperatures.

Ecotrend has introduced world's advanced aerated concrete production line to produce AAC blocks and ALC panels (ALC panel belongs to prefabricated building materials). The company has annual production capacity of 400,000 cubic meters, which is the largest and only ALC panel manufacturing enterprise with green prefabricated building material in Cambodia. Since it only about 20-minutes driving from Sihanouk Ville Port, thus, Ecotrend is endowed with unique geographical advantage for exporting.
