Starken ACC
Autoclaved Aerated Concrete (AAC) begins with the same process used to mix together to form a slurry. Upon the introduction of aluminium paste as expansion agent, air bubble are introduced throughout the material, generating a low-density lightweight material. The wet concrete is molded into shape using forms, then cut into slabs and block once partially dried. The units are then moved to an autoclave for full curing under heat and pressure, which takes approximately 12 hours.
AAC products are made using slurry mix containing cement, sand, lime and aerating agent. The slurry is poured and moulded to form lightweight blocks, panels and lintels upon which are cured in autoclave. The high-pressure steam-curing mechanism in the autoclave facilitates the curing process of the moulded lightweight concrete, producing physically and chemically stable products that weigh about 1/5 of normal concrete. AAC products contain millions of tiny non-connecting air pockets yielding superior thermal insulation property. AAC products are typically installed to form walls, floors and roofs.
