ABSTRACT:
A process for preparing fire-resisting moldings having an improved mechanical strength by admixing gypsum with crystalline calcium silicate in an amount of 5 to 100 % by weight to the gypsum and water to give a slurry, molding the slurry under pressure and drying the raw articles. The water resistance of the moldings can be improved by the further addition of cement.
