Quick-drying building material composition based on a mineral hybrid binder |
摘要 |
The invention relates to a quick-drying gypsum composition, in particular for use as gypsum filling compound and for the production of floorcoverings, wherein the gypsum composition contains 20 to 70% of a mixture of calcium aluminate and calcium sulfate hemihydrate and/or anhydrite and/or calcium sulfate dihydrate as hydraulic binders and 30 to 80% by weight of fillers, and wherein the weight ratio of calcium aluminate to calcium sulfate hemihydrate and/or anhydrite and/or calcium sulfate dihydrate binders lies in the range from 1:1 to 1:5. Gypsum compositions of this type are characterized by a particularly beneficial shrinkage behavior, such that stresses and cracks in the dried composition can be avoided. At the same time, the gypsum compositions dry to readiness for covering in a time that is compatible with conventional cement filling compounds. |
