Autoclaved aerated concrete (shorted as AAC) is a kind of lightweight precast concrete, it was invented in the mid-1920s and has developed for around 100 years. Since 1980, the production of AAC Blocks continues to increase globally and it is increasingly used by developers, architects, builders around the world, especially for prefabricated building, this is in line with the development trend of the construction industry.
Ecotrend manufactures autoclaved aerated concrete (AAC) or aerated lightweight concrete (ALC) block and panel, it is a composite of cement, lime, and silica sand. Besides, ALC panel uses bidirectional welded steel mesh (reinforcing bar) ，which has been treated with a superior rust preventive liquid and cured with high-temperature, high-pressure steam. A porous silicate board is manufactured for high performance of anti-permeability and sound insulation. It can be divided into external wall panels, partition panels (internal wall panels), floor panels and roof slabs according to the purpose.
AAC blocks and ALC panels are widely used in various projects,such as commercial, factory, and residential buildings etc. The product has the characteristics of convenient installation, wide application range, and high construction accuracy; meanwhile, it can greatly improve the usage performance of the building, and reduce the cost of construction.
