摘　　要：用不同组成、不同细度的水泥标准稠度用水量计算水泥颗粒的堆积孔隙率分析研究了水泥颗粒堆积程度的影响因子。分析结果表明,水泥颗粒堆积孔隙率与R45/n具有良好的相关性,两者呈线性关系;可以将R45/n称之为水泥颗粒堆积状态因子,此值越大,水泥颗粒的堆积越紧密;从R45/n因子的相关参数来看,通过提高水泥中的粗颗粒含量或者拓宽水泥的颗粒分布均能提高水泥颗粒的堆积程度。The factor of stacking state of cement particles has been discussed in this paper, hy means of stacking space rate of cement particles that calculated using standard consistence water demanded of cement which have different composes and fines. The results show that stacking state of cement particles with R45/n has a good liner relationship. R45/71 can be called the factor of stacking state of cement particles, which is the larger, cement particles stack denser. Showing from R45/ n, stacking state of cement particles can be increased by increasing content of coarse particles, also by enlarging the distribution of cement particles.
