1998-9-1  Autoclaved aerated concrete (AAC) is widely used in construction mainly due to its improved insulation properties. Because of its high porosity, AAC is characterized by low weight and strength and high brittleness. Structural elements made of AAC are not common. A structural element should withstand different loadings and perform properly.
