The Aerated block machine is characterized by the advantages of light weight, heat preservation, sound isolation, high strength, processable property, etc. Moreover, the raw materials of the products are abundant. Especially the use of fly ash as the raw material can not only make use of industrial waste residue, reduce environmental pollution and protect tillable field, but also create favorable social and economic benefits. Experience over the past few years has proved that aerated concrete is the perfect wall material to replace the traditional solid clay brick. Aerated Concrete has always accepted strong supports from the policies about reforming of wall material, tax policies and environment protection policies. Aero-concrete block and board have become the important part of new-type construction materials, and possess bright development future.
