| description | PROBLEM TO BE SOLVED: To provide a cement composition from which mortar or concrete having high strength and high workability can be produced simply. SOLUTION: The cement composition comprises portland cement containing 30-60 mass% of 2 CaO-SiO2and silica fume with a BET specific surface area of 5-15 m2/g. Preferably, the portland cement contains at most 6 mass% of 3 CaO-Al2O3and silica fume contains 0.5-5.5 mass% of Al2O3and 0.01-0.025 mass% of SO3. COPYRIGHT: (C)2008,JPO&INPIT |
