Curing products for fresh concretes and mortars, method for their preparation and their use in the treatment of fresh concrete and mortars

摘要

curing compounds for concrete or fresh mortar, characterized in that they contain: - an aqueous dispersion A of a few film-forming synthetic polymer or not permeable to water vapor and compatible with fresh concrete or mortar; - in admixture with at least a "coagulating agent" of said film-forming synthetic polymer in the presence of calcium ions, said coagulating agent being introduced in the form of an aqueous or hydroalcoholic solution or via an aqueous wax emulsion and / or an aqueous dispersion B of a few synthetic polymer or not permeable to water vapor, said aqueous dispersion 8 having been prepared by polymerization in the presence of said coagulating agent.; Sprayed onto the surface of fresh mortars, they form a continuous impermeable film removing by peeling.
