Autoclaved aerated concrete (AAC) rubble for …
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. A classical material recycling is not possible since the properties of AAC rubble …

Waste aerated concrete grit is produced either directly in the aerated concrete plant or subsequently on the building site. The options for handling aerated concrete grit are two. Either it can be used as a construction material, e.g. in the form of light aggregate or as a raw material for the production of aerated concrete. The subject of this article is the verification of aerated concrete ...
Autoclaved aerated concrete for construction in hot regions
The product is autoclaved for 10 hours at 10 atm at 180 OC. The autoclaving initiates a reaction between the calcium and silica to form calcium hydrosilicates. Autoclaved aerated concrete has a low bulk density and a particularly favorable ratio between material strength and bulk density.
