China Green Partition Wall Building Materials AAC Block, Find details about China High Pressure Cellular External Wall Brick, AAC External Wall Block from Green Partition Wall Building Materials AAC Block
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) Lightweight:
The dry density of AAC blocks is generally 400~700kg/m³, which is equivalent to one-third of clay bricks and one-fourth of concrete, meanwhile it is also lower than general lightweight aggregate concrete, if AAC blocks is used , transportation costs, energy and labor costs could be saved.
(2) High strength:
Ecotrend AAC blocks have high dimensional accuracy. If thin-layer mortar is used for masonry, the strength utilization factor is greatly improved. The strength of masonry is about 80% of the strength of the block itself, which is 30% stronger than that of clay bricks. In addition, steel bars can be configured according to design requirements in order to meet different needs.
(3) Seismic:
Due to the lightweight of AAC blocks, the self-weight of the buildings using AAC blocks is greatly reduced, thereby greatly improving the earthquake resistance of the building.
(4) Durability:
Ecotrend AAC blocks is a kind of silicate material, there is no aging problem, and it is not easy to be weathered. It is a durable prefab building materials, and its normal service life can be compared with all kinds of permanent buildings.

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.
