    The autoclaved aerated concrete block (known as AAC block) is a porous concrete product, which is made of cement, lime, silica sand, and plaster as raw materials, aluminum powder as a foaming agent, through the process of ingredients, mixing, pouring, pre-curing, cutting and autoclaving.

    The non-autoclaved aerated concrete is a kind of material that does not require autoclaving, which is formed by mixing and natural curing through adding gas into slurry composed of cement, fly ash, water, and various admixtures by adopting a special process formula. Generally, only small workshops will adopt this process, because it does not require investors to buy autoclave and boiler, which can lower the cost of investment.

    Due to non-autoclaved aerated concrete product lacks necessary curing technology; a lot of performance parameters of aerated concrete block cannot meet the Chinese national standard, such as dry density, thermal insulation, compressive strength, etc. In the absence of professional experimental equipment, you can tell the difference in appearance and weight. Furthermore, Article 3.1.4 of the mandatory provisions of the National Standard GB 50574-2010, clearly stipulated that "aerated concrete products that without autoclaved should not be applied in the wall system". Hence, please carefully check if it is the autoclaved aerated concrete product before purchasing.
