Autoclaved aerated concrete (AAC) is a lightweight cellular concrete that has been used for more than 80 years. Currently, however, no good recycling options for AAC from construction and demolition waste exist. The amount of AAC waste that can be recycled in the production of new AAC is limited because of quality issues. Furthermore, recycling AAC into traditional concrete or as unbound aggregate causes both technical and environmental problems because of the low compressive strength (2-8 MPa)doi:10.5281/zenodo.46405 fatcat:7of33anwwjgj5bipzyj7jtrtya
