摘　　要：水泥是水泥混凝土的重要组成材料之一,其性能对混凝土的工作性能、力学性能和耐久性能有重要的影响。水泥的颗粒特征又是决定其性能的关键因素。本文采用激光粒度分析结合分形理论对6种通用硅酸盐水泥的性能进行了评价。结果表明,水泥粒度分布的分形维数与水泥比表面积和中位粒径等有着良好的相关性,可以作为反映水泥颗粒特征的综合性参数。Cement is an important material of cement concrete, and the influence of its performance on the working performance, mechanical property and durability of concrete is very important. The particle characteristics of cement have important influence on performance of cement. The performance of 6 kinds of common portland cement is evaluated by means of laser particle size analysis and fractal theory. The results show that the fractal dimension of the cement particle size distribution has a good correlation with the specific surface area of cement and the median particle size, and can be used as a comprehensive parameter to reflect the characteristics of cement particles.
