摘要： PROBLEM TO BE SOLVED: To improve workability by coating the upper section of a floor slab with specific quantities of a waterproofing material layer, in which a nonwoven fabric using hydraulic cement and a synthetic-resin emulsion having specific properties as base compounds is buried, and a tack coat layer and conducting asphalt pavement. SOLUTION: The upper section of a reinforced-concrete floor slab 1 is coated with a cold hydration solidification type waterproofing material in 1.5-3 kg/m2 using hydraulic cement and a synthetic resin emulsion having a glass transition point of -30-20 deg.C as base compounds through a primer layer 2, and a coating layer 3 is formed. A reinforcing material such as a nonwoven fabric 4 is stuck onto the layer 3 and impregnated with the waterproof material, the layer 3 is coated with the waterproofing material in 0.5-2 kg/m2 and a coating layer 5 is formed, and the total quantity of the waterproofing material is set in at least 2 kg/m2. A rubber asphalt emulsion in 0.3-0.5 kg/m2 is applied and a tack coat layer 7 is formed, and asphalt pavement 8 is executed. Accordingly, since there is no heating melting process as seen in asphalt in a waterproof layer, work environment can be improved, and the sure waterproof layer can be formed.

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.
