Aerated Autoclaved Concrete (AAC) is made with no aggregates larger than sand, unlike most other concrete building applications in the construction industry. Coupling specialists include quartz sand, calcined gypsum, lime (mineral), concrete, and water. Fly debris from thermal power plants with a silica level of 50-65 percent is utilised as an aggregate in some countries, including India and China. AAC blocks are produced using a variety of raw materials. Flyash or sand is the primary ingredient in Aerated Autoclaved Concrete (AAC). Fly ash makes up 65-70 percent of the mixture, whereas coarse

AAC blocks are produced using a variety of raw materials. Flyash or sand is the primary ingredient in Aerated Autoclaved Concrete (AAC). Fly ash makes up 65-70 percent of the mixture, whereas coarse sand makes up 55-65%. Cement 53 GRADE OPC has a percentage proportion of 6-15 percent with Flyash and 10-20 percent with sand.
When compared to other cement concrete materials, autoclaved aerated concrete (AAC) has numerous advantages. The primary benefit is that it is both cost-effective and environmentally benign, with minimal environmental impact. Because the topsoil of the earth's surface is not used in the production of AAC blocks, it emits extremely less carbon dioxide when compared to red clay bricks. Because AAC blocks are an industrial product made with machines, the end product quality is excellent, homogeneous, and consistent. Because the blocks are even and perfectly finished on all sides, the thickness of the wall plaster is lowered. Because of its small weight, the structural system will have less dead weight, resulting in steel and concrete savings.
In today's construction sector, autoclaved aerated concrete (AAC) is an unique and one of the most acceptable and sustainable building materials. As a result of the productive use of recovered industrial waste, such as fly ash, AAC blocks can be categorised as a sustainable construction material. According to the rates in India in 2019, the production price of AAC blocks at the manufacturing plant ranges from Rs. 3200/- to Rs. 3600/- per cubic metre. Because to the inherent qualities of AAC blocks, construction processes are quick and efficient. As a result, autoclaved aerated concrete (AAC) has become an efficient building construction material that is used in a wide range of residential, commercial, and industrial buildings. It has been used in the Gulf countries for 40 years, Europe for 70 years, and Australia and South America for 20 years.
