采用Ｘ射线小角散射技术对水泥石中微孔孔界面结构，特别是孔界面的分维进行了实验研究，并对这些结构参数对水泥石比表面积和强度的影响作了分析讨论．研究表明：水泥石中的微孔界面不具有分明的边界，而是有约５×１０－１０ｍ的过渡层；水泥石中微孔界面具有分形结构特征，界面分形维数接近于３；水泥石的抗弯、抗压强度及比表面积等均与微孔界面分维存在较好的联系．
X-ray small-angle scattering technique was used to investigate the fractal dimension of pore structure in micropores, especially the fractal dimension of pore interface. The influence of these structural parameters on the specific surface area and strength of cement was also discussed. The results show that the micropore interface in cement stone does not have a clear boundary, but a transition layer of about 5 × 10-10m. The micropore interface in cement stone has the fractal structure with the fractal dimension close to 3; The flexural, compressive strength and specific surface area of fractal dimension have a good relationship with the microporous interface.
