Abstract: A composition contains a mixture of an inorganic binder and alkyl-modified silsesquioxane resin particles, where the alkyl-modified silsesquioxane resin particles are distributed throughout the inorganic binder and have an average particle size in a range of 20 to 200 nanometers as determined by dynamic light scattering.

Abstract: A process for increasing the hydrophobicity of a porous product by treating the product, or a composition providing for the product, with a water repellent material, characterized in that the porous product or a composition providing the product, is treated with an aqueous suspension of microcapsules where the microcapsules comprise a water repellent organosilicon core material selected from an organosilane, a partially condensed organosilane and a branched siloxane resin, and a shell of a silicon-based network polymer comprising silica units.

Abstract: The present invention relates to cementitious materials, which exhibit a hydrophobic character, and to a process for making cementitious materials hydrophobic, and to a granulated additive for rendering cementitious material hydrophobic. An emulsifier for the organosilicon component is deposited on the particulate carrier together with the organosilicon component and the binder. The hydrophobing agent permits to impart instantaneous hydrophobicity to cementitious materials.
