AAC (Autoclaved Aerated Concrete) Introduction
Autoclaved Aerated Concrete, also known as Aircrete, is a lightweight, load-bearing, high-insulating, durable building product, which is produced in a wide range of sizes and strengths.AAC offers incredible opportunities to increase building quality and at the same time reduce costs at the construction site. AAC is produced out of a mix of quartz sand and/or pulverised fly ash (PFA), lime, cement, gypsum/anhydrite, water and aluminium and is hardened by steam-curing in autoclaves. As a result of its excellent properties, AAC is used in many building constructions, for example in residential homes, commercial and industrial buildings, schools, hospitals, hotels and many other applications.
It has light ,keeping temperature , Environmental protection,can’t burn and other advantages. It has a wide prospect of market.it is the main building material in the future. As normally, concrete density is usually 1600-2400kg/m3,but aerated concrete are 500kg/m3,600kg/m3,700kg/m3.It has not the big grain and use silicon material (for example: fly ash,sand,stone dust and others ),through making the material small for example sand, they can be used directly if has enough degree of small (for example fly ash, Mixing calcium material lime, cement, water to a special ratio, then add the aluminum dust and the additive, then Make the aluminum dust and the special ratio have a Chemical reflect. then produce Hydrogen to make the concrete slop to expanding or swell and foam. Next put them into the curing room to concreting cutting steaming curing, At last, there will become the light brick and the porous rate is 70-80%
