A method for forming and imparting water repellency on concrete -, mortar -, cement the form of bodies with a silicone resin

摘要

The process for the simultaneous casting and waterproofing of elements made of concrete, mortar, cement or the like comprises, before casting the concrete, cement or the like, covering the inside of the mould with a composition comprising a resin which is a silicone copolymer having the formula (I): M alpha D beta T gamma Q delta (OR) epsilon , wherein M = R1R2R3SiO1/2; D = R4R5SiO2/2; T = R6SiO3/2; Q = SiO4/2, in the absence of cross-linking agent of the hydrolyzable silane type and curing catalyst in the composition. The invention relates to the cast element thus obtained and the release and waterproofing compositions.
