摘　　要：以水泥颗粒的粗粉微集料效应为理论依据,研究了不同水泥颗粒群对水泥性能的作用。结果表明,对水泥性能影响幅度最大的为水泥中的粗颗粒群和微粉颗粒群,中间颗粒的影响幅度远小于粗粉和微粉;粗颗粒群含量的提高有利于水泥使用性能的改善,而微细颗粒群含量的增加有利于力学性能的发挥。The effect of cement particle size distribution on cement properties has been investigated, based on the theory of microaggregate effect. The results show that the particles effect on properties of cement is mostly contributed by coarser particles and su- per-finer particles and little by the medium particles. The increase of coarser particles is benefit for modifying the workability of cement, and the increase of super-finer particles benefit cement strength.
