摘　　要：提供了一个能够有效测量不同颗粒形貌特征的系统,即数字图像处理系统,将运用该系统得到的粉煤灰颗粒群特征数据,如粒径分布、圆度和填充度等作了灰色关联分析,研究了粉煤灰颗粒群特征与水泥基材料宏观性能的关系,为粉煤灰的有效利用提供了理论依据.Digital image processing system to measure various morphological characteristics of particles effectively was presented. Grey correlation analysis by the datum such as particle size distribution, roundness and fullness ratio of fly ash from image analysis was conducted. The relationship between characteristics of particle group and strength, fluidity property of fly ash cement were investigated. The results of this study provide theoretical evidence for the good use of fly ash.
