摘要 | PROBLEM TO BE SOLVED: To obtain a waterproof composition excellent in crazing follow-up properties and shear strength by compounding a hydraulic cement alone or a mixed powder thereof with a filler with a synthetic resin emulsion having a specific glass transition temperature. SOLUTION: This hydration coagulating type waterproof composition is obtained by compounding 100 pts.wt. of a hydraulic cement such as a normal Portland cement, a highly early strength Portland cement, a super highly early strength Portland cement, a blast furnace cement, a fly ash cement or an alumina cement alone or a mixed powder thereof prepared by adding a filler such as calcium carbonate powder, silica sand, fly ash or talc in an amount of 0-300 pts.wt. based on 100 pts.wt. of the cement thereto with 100 pts.wt. of a synthetic resin emulsion having a glass transition point (Tg ) within the range of -30 to -20 deg.C and a resin solid content within the range of 25-70 wt.% such as an acrylic, an ethylene-vinyl acetate-based or an SBR-based one. Components added to a cement mortar such as an antifoaming agent, a thickener or a plasticizer, as necessary, can be added thereto. | ||||||
