摘　　要：分析了含有矿物掺合料的C3S胶凝体系固体体积的变化 ,定量研究了不同水胶比及水化程度下矿物掺合料颗粒对C3S胶凝体系的填充密实作用 ;采用颗粒堆积模型 ,讨论了矿物掺合料颗粒的相对粒径、体积含量对颗粒混合物体系堆积密实度的影响 .从物理和化学两方面 ,系统研究了矿物掺合料颗粒对C3S胶凝体系的填充密实作用 .The variation of solid volume of C 3S cementitous system was analyzed to study quantitatively the filling role of mineral blends under different water to binder ratios and degrees of hydration. The effects of relative particle diameter and particle volume fraction on the packing density of particles mixtures were discussed by granule packing model. The filling role of mineral blends in cementitious system was studied both physically and chemically.
