Abstract

994,061. Plasterboards. VEREINIGTE BAUSTOFFWERKE BODENWERDEN G.m.b.H. July 19, 1961 [Aug. 9, 1960], No. 26229/61. Heading E1B. A plasterboard comprising a filling of plaster and/or anhydrite mortar sandwiched between pasteboards is sprayed with water or subjected to the action of steam for from 1 to 24 hours either before or after the filling has hardened so that the properties of the board are improved. The filling may comprise a plaster containing retarding or accelerating agents and the wetting is such that the water or steam permeates through to the filling.
