Autoclaved Aerated Concrete Research Papers -

Autoclaved Aerated Concrete (AAC) is an ultra-light concrete masonry product. It can weigh as little as 1/5 as much as ordinary concrete due to its distinct cellular structure featuring millions of tiny pockets of trapped air. This cellular structure gives AAC a number of exceptional physical characteristics.
