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.
La présente invention concerne des matières cimentaires qui présentent des propriétés hydrophobes, un procédé permettant de produire des matières cimentaires hydrophobes et un additif granulé destiné à conférer à la matière cimentaire des caractéristiques hydrophobes. Un émulsifiant destiné au composant d'organosilicium est déposé sur le support particulaire avec un composant d'organosilicium et le liant. L'agent hydrophone permet de conférer instantanément des propriétés hydrophobes aux matières cimentaires.
