AAC Blocks also known as autoclaved cellular concrete ( ACC ) or autoclaved lightweight concrete ( ALC ), was invented in the mid-1920s by the Swedish architect and inventor Johan Axel Eriksson. It is a lightweight, precast building material that simultaneously provides structure, insulation, and fire and mold resistance. AAC products include AAC Blocks, AAC Wall Panels, AAC floor and roof panels ,and AAC lintels .
AAC Blocks ( Autoclaved Aerated Concrete - " AAC ") a unique and excellent type of building materials due to its super heat, fire and sound resistance, AAC blocks is lightweight and offers ultimate workability, flexibility and durability. Its main ingredients include sand, water, quicklime, cement and gypsum. The chemical reaction due to the aluminum paste provides AAC its distinct porous structure, lightness, and insulation properties, completely different compared to other lightweight concrete materials.
Aerated Concrete Blocks - AAC is produced from the common materials lime, sand, cement and water, and a small amount of rising agent. After mixing and molding, it is then autoclaved under heat and pressure to create its unique properties. AAC has excellent thermal insulation and acoustic absorption properties. AAC is fire and pest resistant, and is economically and environmentally superior to the more traditional structural building materials such as concrete, wood, brick and stone. AAC blocks begins as a slurry mix of lime, sand, cement and water, and a small amount of rising agent. For reinforced panels, a welded steel cage element is placed into the molds prior to pouring in the slurry. Once the slurry is poured in, the mixture begins to foam and rise up completely around the reinforcing cage. Once the rising process is complete the cage and the AAC are completely integrated and ready to be placed into the autoclave for the curing process.
