Autoclaved Aerated Concrete Panel (AAC) Is the porous concrete, which composed of quartz sand, aluminum, lime, etc. And because it is noncombustible, it will not burn or give off toxic fumes. AAC floor systems bear directly on top of AAC walls. Autoclaved aerated concrete (AAC), a form of cellular concrete, is a low-density cementitious product of calcium silicate hydrates in which the low density is obtained by the formation of macroscopic air bubbles, mainly by chemical reactions within the mass during the liquid or plastic phase. Blocks are stacked similarly to conventional masonry, but with a thin-bed mortar, and panels are stood vertically, spanning full-story heights. Autoclaved Aerated Concrete Manufacturing Equipment Complete Plant Available Panel Plant 8000, Block Plant 3000 300 x 200 x 610 ASTM C 1452 (Reinforced AAC Wall constructions) AAC / Lightweight Concrete Plant for. Originally Ytong autoclaved aerated concrete in Sweden was produced with alum shale, whose combustible carbon content was beneficial in the production process. Its light weight/cellular properties make it easy to cut, shave, and shape, accept nails and screws readily, and allow it to be routed to create chases for electrical conduits and smaller-diameter plumbing runs. [11] The curing process also saves energy, as the steam curing takes place at relatively low temperatures and the hot steam generated in the autoclaves is reused for subsequent batches.[12]. It can be categorized into external wall panels, partition panels (internal panels), roof panels and floor panels according to the usage. NAAC is lighter then conventional concrete. Once cured, this type of concrete contains about 80% air. Aerated Concrete (AAC), also known as Autoclaved Cellular Concrete (ACC), and Autoclaved Lightweight Concrete (ALC), is a lightweight, precast, foam concrete building material invented in the mid-1920s that provides structure, insulation, fire and mould resistance, and a variety of other benefits.
