本研究中，利用20～30％的比表面积为7000～8500cm2／g的超细高炉矿渣和10％的硅灰取代等重量水泥并使用高效减水剂在水／胶比为0．25的条件下配制了坍落度大于22cm、28天抗压强度为100MPa且60天抗压强度不小于110MPa的高性能混凝土。本文分析了所得高性能混凝土抗压强度和劈裂抗拉强度的发展规律，并且探讨了超细矿渣和硅灰在水泥水化和混凝土硬化过程中所起的叠加效应。 In this study, 20 to 30% of ultra-fine blast furnace slag with a specific surface area of ​​7,000 to 8500 cm2/g and 10% of silica fume was used in place of equal weight cement and a superplasticizer was used at a water/binder ratio of 0.25. A high-performance concrete with a slump of more than 22 cm, a 28-day compressive strength of 100 MPa, and a 60-day compressive strength of not less than 110 MPa was prepared. This paper analyzes the development law of compressive strength and splitting tensile strength of the resulting high performance concrete, and discusses the superposition effect of ultrafine slag and silica fume in the process of cement hydration and concrete hardening.
