Preparation of new cementitious system using fly ash and

We experimentally studied the interaction between pozzolanic material (fly ash) and dehydrated autoclaved aerated concrete (DAAC). The DAAC powder was obtained by grinding aerated concrete waste to particles finer than 75μm and was then heated to temperatures up to 900 °C. New cementitious material was prepared by proportioning fly ash and DAAC, named as AF.
