利用分形几何学理论定量表征了几种水泥断口表面的微观形貌特征,并且考察了断口表面分形维数与其抗压强度的关系.结果表明,水泥断口的表面分形维数介于2～3之间,且线性回归分析的相关系数均大于0.98,强的相关性表明实验所选用的水泥断口具有明显的分形特征;水泥的抗压强度与其断口表面分形维数值呈正相关关系.
The fracture surface microstructure of some kinds of cement are characterized based on fractal theory, and the relationship between the fracture surface fractal dimension of cement and its compressive strength is investigated. The rusults indicate that the fracture surface fractal dimension of cement is in a range from 2 to 3, the correlation coefficients are all larger than 0. 98, the strong correlation coefficient shows that the fracture surface of cement is evident fractal,and the relationship between surface fractal dimension of cement and its compressive strength is positive correlated relation.
