Aerated concrete, also known as autoclaved aerated concrete (AAC), is a lightweight building material made from a mixture of cement, lime, water, and a small amount of aluminum powder. The aluminum reacts with the other ingredients to create tiny air bubbles, which give the concrete its aerated properties. This results in a material that is not only lighter than traditional concrete but also provides excellent insulation. Due to its unique properties, aerated concrete is commonly used in construction for walls, floors, and roofs. It is fire-resistant, energy-efficient, and easy to work with, making it a popular choice for both residential and commercial buildings. Its eco-friendly nature also appeals to sustainable building practices.
