Manufacturing of Autoclaved Aerated Concrete (AAC): Present Status and Future Trends
Recent researches have indicated the manufacturing of several useful products by using different industrial wastes all over the world. The materials remain as a waste till their potential to right use is understood. The solid waste in India has emerged as a great threat to the environmental health of the country. Nowadays, building materials are manufactured from various environmental wastes based on needs and availability. An overview has been given on the manufacturing of autoclaved aerated concrete (AAC), one of the potential building materials. The replacement of major raw material (sand) with the solid/industrial wastes in manufacturing of AAC leads toward a sustainable process. In this paper, present status on manufacturing of AAC as well as possible utilization of industrial wastes for its production is presented. A complete industrial manufacturing process of AAC block along with advantages, applications, cost-benefit analysis, challenging issues, and future scopes have been highlighted.
