SELF-FOAMING GYPSUM COMPOSITIONS
A dry gypsum composition, in particular for preparing foamed gypsum compositions, comprises:a) 10 - 50 wt.-% of a gypsum based binder;b) 30 - 60 wt.% of aggregates, optionally comprising lightweight aggregates;c) 1 - 15 wt.-%, especially 2 - 9 wt.%, of a foaming agent capable of producing carbon dioxide;d) 0.5 - 10 wt.%, especially 1 - 6 wt.%, of an acidic agent, capable of reacting with the foaming agent under aqueous conditions for generation of carbon dioxide;whereby the proportions are given with respect to the total weight of the dry gypsum composition.
