粉煤灰水泥浆体的分形结构研究

Study on Fractal Structure of Fly Ash Cement Pastes

简要介绍了用Ｘ射线小角散射分析技术测定多孔固体材料中气孔固体界面分形维数的理论，并将这一理论用于测定粉煤灰水泥浆体的分形结构．实验结果表明，粉煤灰水泥浆体具有面分形结构特征．此外，对分形维数与抗压强度的关系也进行了探讨．

In this paper,a method to determine the fractal dimension of pore solid interface in porous solid materials by the small angle X ray scattering(SAXS) is introduced.This method is also used to determine the fractal structure of fly ash cement pastes.Experimental results show that fly ash cement pastes have surface fractal structure characteristics.In addition,the relationship between the fractal dimension and compressive strength is approached.
