火山灰效应对水泥与混凝土强度的影响(英文)

Contribution Rate of Pozzolanic Effectto Strength of Cement and Concrete

介绍了单位重量熟料或单位重要水混对含活性矿物外加剂的水泥或混凝土强度的影响规律，其判据是水泥中单位重要熟料比强度、混凝土中单位重要水泥比强度、水泥或混凝土中火山灰效应比强度、比强度比以及火山灰效应对强度的作用率等。采用这些数据以及火山灰效应图，定量分析了含活性矿物外加剂的水泥或混凝土硬化过程中的影响因素和火山灰效应的作用规律。

In this paper, a concept of contribution of unit clinker or unit cement to the strength of cement or concrete with active mineral additives was introduced. Some definitions are given to specific strength of unit clinker in cement, specific strength of unit cement in concrete, specific strength of pozzolanic effect in cement or concrete, specific strength ratio and contribution rate of pozzolanic effect to strength. Using these indexes and a diagram of pozzolanic effect, the magnitude, influencing factors and regularity of pozzolanic effect during hardening of cement and concrete with active mineral additives can be analysed quantitatively.
