HIGH STRENGTH CONCRETE COMPOSITION AND MANUFACTURING METHOD OF HIGH STRENGTH CONCRETE CURED BODY

摘要

PROBLEM TO BE SOLVED: To provide a high strength cement mortar composition having high compression strength without needs for large scale and special manufacturing facility.SOLUTION: There is provided a high strength concrete composition containing cement, inorganic fine powder, water, a fine aggregate, a coarse aggregate, a water-reducing agent, an antifoam agent and metal fine particles, the cement contains 10.0 mass% to 70.0 mass% of CS and 10.0 mass% to 70.0 mass% of CS, the inorganic fine powder contains silica fume. Also there is provided a manufacturing method of a high strength concrete cured body including a pre-curing process for conducting curing in air at 15 to 25°C for 1 day to 5 days, a primary curing process for conducting curing in water or air at 20 to 60°C for 1 day to 7 days and a second curing process for conducting curing in water or air at 80 to 200°C for 1 day to 21 days.SELECTED DRAWING: None
