Abstract
A mixture for the production of autoclaved aerated concrete, containing a binder with a specific surface area greater than 2500 cm2/g according to Blaine and possibly a microaggregate with a specific surface area of 1500 - 2500 cm2/g according to Blaine, as well as water and preferably additives such as blowing agents and surfactants, the binder comprising a silica source in the form of a component or mixture of components selected from the group consisting of quartz sand, fossil fuel fly ash, blast furnace slag, and the binder also comprising a calcium source in the form of a component or mixture of components selected from the group consisting of lime, fossil fuel fly ash, blast furnace slag, cement and gypsum, and the molar ratio of the amount of calcium source to the amount of silica source in the mixture is 0.25 - 0.95, characterized in that the mixture contains 10-90% by weight of raw material with glass phase content over 90% by weight, over 10% by weight of alkali in the form of Na2O and K2O oxides and over 60% by weight of SiO2. The latter raw material is preferably glass cullet.
