Evaluation of Autoclaved Aerated Concrete Fines for ...

11/11/2019  Along with the increase of autoclaved aerated concrete (AAC) production, the amount of scrap waste (industrial by-products) is increasing. AAC waste, however, is not yet being fully reused or recycled and is discarded without any treatment in most developing countries. In this study, AAC fines were tested as effective and economic adsorbents for the removal of

Durability of Autoclaved Aerated Concrete

Autoclaved aerated concrete (AAC) is produced of natural inorganic raw materials such as sand, lime, cement, water and the rising agent aluminium. AAC has an unique structure, formed by millions of small air pores, which leads to an optimum correlation between compressive strength and low materials weight. Moreover, air has a low thermal conductivity which makes AAC one of the best insulating ...
