High-strength mortar, high-strength concrete, method for producing high-strength mortar hardened body, method for improving durability of structure, and premix material for high-strength mortar

摘要

PPROBLEM TO BE SOLVED: To provide high strength mortar having workable fluidity and being excellent in chemical durability, high strength concrete, a method for manufacturing a high strength mortar hardened body, a method for improving the durability of a structure and a premixed material for high strength mortar. PSOLUTION: The high strength mortar is the mixture of alumina cement, fine aggregate, a chemical admixture for concrete and water. 30 vol.% or less of alumina cement is replaced by molten slag. The high strength mortar where the rate of the weight (mass) of water to the sum of the weight (mass) of alumina cement and the weight (mass) of the molten slag is 20% or less and the method for manufacturing the high strength mortar hardened body where the high strength mortar is cured at 30C or higher are provided.
