摘要: 基于压汞实验探讨了水泥基材料多孔结构可能存在的三种分形模式：孔隙分形，孔隙–固相界面分形及固相分形。结果表明，固相分形是水泥基材料中最有可能存在的分形模式，且分形维数具有尺度依赖性。其次，建立了固相分形模型模拟水泥基材料多孔结构的一般方法。
Abstract: Starting from the common mercury intrusion porosimetry test, the fractality in cement based materials is examined, which might be the pore mass fractal, the pore surface fractal or the solid mass fractal. The results indicate that the MIP test reveals the most probable fractal type being the solid mass fractal, and meanwhile the fractal dimension depends on the scale of interest. Moreover, a general approach of the solid mass fractal model is proposed to simulate pore structure in cement based materials.
