Autoclaved Aerated Concrete (AAC) is a lightweight, energy-efficient, and eco-friendly building material that has gained significant popularity in the construction industry. Its unique combination of properties, including thermal insulation, fire resistance, and load-bearing capabilities, has made it a favored choice for sustainable building solutions worldwide. This article explores the growth of the Autoclaved Aerated Concrete market , its key advantages, applications, and its contribution to sustainable construction practices. 1. Understanding Autoclaved Aerated Concrete (AAC) AAC is a precast, cellular concrete material manufactured through a unique process that involves the use of cement, lime, water, and an aerating agent. During production, millions of tiny air cells are formed within the concrete, resulting in a lightweight and porous structure. The concrete mixture is then poured into molds, and after a curing period, it is cut into blocks or panels, ready for use in const
