摘　　要：已有的水泥粉体颗粒堆积模型有一些不足，不能完全满足水泥粉体颗粒这一特定的体系，为了实现水泥的高效应用，本文借助等径球理论在Horsfied堆积模型基础之上提出一种新的PH堆积模型。满足该模型粒度分布要求的粉体颗粒具有较高的堆积密度和较少的细颗粒含量，同时增加了3～32μm部分颗粒，应用于水泥粉体颗粒体系后，水泥水化样具有较高的抗压强度和较低的孔隙率。The existing cement powder particle packing models have some defects and can not fully meet the particular system of cement powder. With the help of equal diameter ball theory, in order to achieve efficient use of the cement, this paper propose a new PH packing model above the Horsfied packing model. Powder particles which meet the requirements of the particle size distribution of this model has higher packing density, less content of fine particles and increasing the content of particles of 3-32 ~m portion simultaneously. The cement hydration samples have higher compressive strength and lower porosity when it used in cement powder particle system.
