AAC Block History and Features (DY Series)

AAC block has developed nearly one hundred years abroad and has become a mainstay part of construction industry. China has introduced this technology for about 40 years and thus technology process and equipments are becoming mature. The aerated concrete is characterized by light volume weight, good heat insulation and sound insulation, adequate intensity plus abundant sources of raw materials, especially fly ash. Thus developing aerated concrete can make the comprehensive use of industrial waste slag, control environmental pollution, savearable land, and bring good social and economic effects, thus being an ieal wall material replacing traditioal solid clay bricks. With the strong support of policies of developing new wall materials, tax and environmental protection, the aerated concrete products have developed into an important part of new building materials, with a bright market prospect. Tthe aerated concrete can be produced in different technology precess according to types and quality of raw materials and the main equipment conditions etc. But generally the following process is used: Pour moderate water into fly ash or silica sand and grind them into slurry; Pour powdered lime, cement and foaming agent mix; And pour them into mold frame wait until they foam and harden; Cut into blocks or boards; Send them into autoclave under high temperature and saturated vapor; Porous and lightweight aerated concrete products come into being.
