摘要： PROBLEM TO BE SOLVED: To make a cement-based hardened product sustain mildewproof and seaweedproof effects for a long period. SOLUTION: Sodium silicate is reacted with calcium hydroxide produced by a hydrating reaction of a cement to produce insoluble calcium silicate, which is capable of densifying the structure of the surface of the cement-based hardened product and imparting waterproofness thereto. A waterproof agent comprising an aqueous polymer dispersion as a principal ingredient is sprayed just after placing the concrete and carrying out the finishing to thereby form a coating layer of a continuous resin having 2-3 mm film thickness. The coating layer is the so-called polymer concrete and is capable of forming a dense structure which is firmly bonded to the cement hardened product or an aggregate. Thereby, the coating layer is excellent in waterproofness and chemical resistance.
