Abstract

An inorganic matrix building material with enhanced water impermeability is prepared by curing an inorganic curable matrix and at least one particulate hydrophobic silicone resin substantially uniformly incorporated within the matrix, the at least one hydrophobic silicone resin being selected from the group consisting of a TD resin, an MQ resin, an MT resin, an MQT resin, and combinations thereof. In certain particular instances, the at least one hydrophobic silicone resin is a TD resin. The curing takes place at elevated temperature, optionally at elevated pressure.
