为定量表征不同混凝土界面过渡区的微观形貌,引入表面分形维数参数,并用投影覆盖法实现其求算.研究结果表明,界面过渡区的表面形貌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0.95,强的相关性表明所选用的界面过渡区的表面形貌具有明显的分形特征.
In order to characterize the surface morphology of different kinds of the interfacial transition zone (ITZ) in concrete quantitatively, the fractal dimension was introduced and calculated by the covering projection method. The results show that the surface fractal dimension of the interfacial transition zone in concrete morphology is in the range of 2 to 3, and the correlation coefficients of linear regression analysis are greater than 0.95,and strong correlation indicates that the selected surface of interfacial transition zone morphology has obvious fractal characteristics.
