HYDRAULIC CEMENT COMPOSITION, CEMENT CONCRETE COMPOSITION, CEMENT CONCRETE HARDENED BODY AND METHOD OF PRODUCING THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide a cement concrete hardened body or a cement concrete structure having excellent acid resistance, sulfate resistance and neutralization resistance by using a specific hydraulic cement composition or a cement concrete composition. PSOLUTION: The hydraulic cement composition contains CaO and AlSB2/SBOSB3/SB-SiOSB2/SB. The hydraulic cement composition contains 5-300 pts. of -2CaO-SiOSB2/SBand 100 pts. of glass-based hydraulic compound containing 40-55 pts. of CaO, 30-40 pts. of AlSB2/SBOSB3/SBand 10-25 pts. of SiOSB2/SB. The hardened body of the cement concrete composition is steam-cured or autoclave-cured, or steam cured or autoclave-cured in water and contains the hydraulic cement composition. The method of producing the same is provided. The cement concrete structure is obtained by lining the existing cement concrete surface with the hydraulic cement composition.
