摘要
水泥基材料的颗粒特征与其性能直接相关。利用他人进行的颗粒特性(包括粒级分布、中位径、比表面积等)与性能(活性、需水性、强度等)的试验数据,用分形理论进行了分形维数的计算与分析。结果表明,分析维数与水泥基材料的比表面积、中位粒径、需水量和机械强度等性能间存在良好的相关性,可以作为反映材料颗粒特征的综合性参数。
The grain character of cement-based material is directly related to its physicochemical property. By others＇ experiment da-ta of grain character as grain distribution, median diameter, specific area, etc. and the physicochemical property as activity, water amount for normal consistency, strength, etc. calculated and analysed the fractal dimension with the fractal theory. The results show that there exists perfect relativity between the fractal dimension and cement-based material＇s specific area, median diameter, water amount, strength, etc, and the fractal dimension can be used as the Comprehensive parameter to show the grain＇s character.
