Autoclaved aerated concrete (AAC) rubble for new recycling
Sep 01, 2018· The use of AAC rubble to produce new autoclaved aerated concrete is possible only to a limited extent due to conceptual reasons. In literature, maximum concentrations of approximately 15 M.-% are reported as a substitute for virgin raw materials 1, 4. Often, these amounts are completely covered by the production waste of the plants.
