采用Ｘ射线小角散射技术对硅灰水泥石中微孔孔表面的分形结构进行了实验研究，并测定其分形维数，同时分析探讨了孔表面分维对孔比表面积、硬化水泥浆体强度等的影响．研究表明，水泥石中微孔孔壁是相当粗糙的，并且均具有分形结构的特点，表面分维与３较为接近；水泥浆体的抗弯、抗压强度以及孔内比表面积等均与微孔表面的分形维数存在一定的联系．
Small-angle X-ray scattering technique was used to study the fractal structure of micropore pores in silica fume cement. The fractal dimension of the pores was measured, and the fractal dimension of pore surface area and the strength of hardened cement paste were analyzed. Impact. Studies have shown that the pore walls of the cement stone are rather rough, and all have the characteristics of fractal structures. The surface fractal dimension is close to 3; the bending strength, compressive strength and specific surface area of the slurry are all similar There is a certain relationship between the fractal dimension of the hole surface.
