Abstract

1483585 Water-proofed gypsum products UNIE VAN KUNSTMESTFABRIEKEN BV 5 Nov 1974 [5 Nov 1973] 51344/73 Heading C1A A gypsum is formed by setting (as defined) anhydrous or partly anhydrous calcium sulphate to form a paste, wherein before or during setting there is incorporated into the calcium sulphate material one or more compounds which in solution form ions of Sr, AlF, Ti, Mn, AlF 5 , HPO 4 or rare earth metal, and the paste is contacted with ammonia after setting and before or during drying to obtain an alkaline reaction thereof.
