摘　　要：本文讨论了矿物掺合料产生填充效应、形态效应和活性效应的条件。只有矿物掺合料的粒径等于或小于水泥颗粒的0.414倍才能产生良好的填充效应;圆形度大于水泥的矿物掺合料才产生形态效应;水灰比较低时,只有在长期潮湿养护条件下才能产生明显的活性效应。Prerequisites to mineral admixtures being with filling effect, morphologic effect and activity effect are discussed in this paper. When the mean particle size of a mineral admixture is not greater than that of cement particle by 0.414 times, it will have good filling effect, and when the average roundness of its particles is larger than that of cement particles it will give morphologic effect. In the case of low water to binder （cement ＋ mineral admixture） ratio a long-term wet curing is needed to produce activity effect in.
