Paper Title
Study of Autoclaved Aerated Concrete

Abstract
AAC was invented in mid-1923 in Sweden. It is also known as Autoclaved Cellular Concrete (ACC) or Autoclaved Lightweight Concrete (ALC). Production process of AAC is fairly simple. It is made with made with a mixture of fly ash, lime, cement, gypsum, an aeration agent and water. Aeration process, imparts it a cellular light-weight structure. AAC products are precast in various sizes and provide structure, insulation, and fire and mold resistance.AAC products are offered in various shapes and sizes including but not limited to blocks, wall panels, floor and roof panels, and lintels. Use of Autoclaved Aerated Concrete (AAC) blocks in construction industry in India offers interesting proposition for various segments in the society. For a project developer it means faster and lower cost construction. For environmentally conscious it means eco-friendly products and for those who occupy buildings built with AAC blocks it means better safety and lower energy costs for cooling or heating. Primary raw material for AAC is fly ash. Keywords - AAC on building structures.
