| Abstract: | 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. |
