CEMENTITIOUS MATERIALS

摘要

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