应用密实堆积模型、Powers模型、CaO-SiO2-HsO系统三元相图分析分别对混合材效应与活性混合材掺量的关系进行了理论分析．指出活性混合材掺量受混合材颗粒与水泥颗粒的平均粒径比、水固比、超塑化剂的质量、水泥的水化程度、水泥的化学组成、混合材的品质和粒径等多种因素的影响。一般情况下，理论计算值的范围是15％～30％，而实际情况总是低于这个范围，这主要是因为减水剂的减水效果不佳和在常温养护下水泥的水化程度较低。 The ternary phase diagram analysis of the compact stacking model, the Powers model, and the CaO-SiO2-HsO system was used to analyze the relationship between the effect of the mixing material and the content of the reactive mixture. It was pointed out that the content of active admixture was affected by the ratio of the average particle size of the admixture to the cement particles, the ratio of water to solid, the quality of the superplasticizer, the degree of hydration of the cement, the chemical composition of the cement, the quality and particle size of the admixture, etc. The influence of various factors. Under normal circumstances, the theoretical calculation range is 15% to 30%, and the actual situation is always lower than this range. This is mainly due to the poor water-reducing effect of water-reducing agent and the degree of hydration of cement under normal temperature maintenance. low.
