Abstract

A process is disclosed for producing water-repellent, porous plaster moulded bodies, in particular porous plaster panels, from plaster powder, mixing water, foam and if necessary other usual additives, by admixture of alkylhydropolysiloxanes. The alkylhydropolysiloxanes are added to the mixing water or to partial streams thereof that contain the usual additives, then the mixture is intensively mixed in a turbulent stream in a tube several meters long.
