Autoclaved Aerated Concrete block is referred to as AAC block. It is a precast, lightweight building material comprised of sand, cement, lime, gypsum, water, and an expansion agent from natural raw materials. The material acquires a cellular structure as a result of the expanding agent’s creation of air pockets. In an autoclave, a high-pressure vessel, steam under pressure is used to cure AAC blocks. This procedure produces a construction material with exceptional thermal insulation capabilities, fire resistance, and sound insulation that is lightweight, dimensionally precise, and very durable. The ease with which AAC blocks can be handled, cut, and installed as well as how quickly and cheaply they can be installed make them a popular choice for building projects.
