摘　　要：采用激光粒度测量技术、扫描电镜和热导式微量热技术对-βC2S单矿物经高能球磨后的颗粒特征与水化活性进行了测试,运用分形理论对测试结果进行了分析。结果表明,分形维数与-βC2S磨矿的粒度分布、比表面积、中位径和水化速率等参数间存在良好的相关性,可以作为反映粉体物料颗粒特征的综合性参数。The characters and hydration activity β-C2S single mineral through high energy ball grinding were tested by using laser granularity survey technology, scanning election microscopy（SEM） and the heat conduction microcalorimetry technology. The utilization fractal theory was used to analysis the test results. The results indicat that there are goal relevance among the fractal dimension and β-C2S＇ s grain-size distribution, specific surface area, median diameter and hydration velocity and so on, the fraetal dimension could be used as the comprehensive parameter reflecting the characters of powders.
