AAC blocks also known as Autoclaved Aerated Concrete Blocks or Light Weight Concrete Blocks which are widely used in construction. AAC blocks are extremely light weight and easy to install, nail, drill and cut for pipes & conduits. AAC blocks are manufactured by mixing of flyash, cement, lime, gypsum and aluminum powder which later cut in to required dimensions, cured in a high temperature and high pressure autoclave/steam chamber. AAC blocks are Highly thermal insulated, acoustic insulated, fire resistant, pest resistant, light in weight, long life, seismic resistant highly efficient blocks used for various applications across the world from last 6 decades.
