Abstract　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.
Key words　fractal;SAXS;fly ash-cement pastes;compressive strength
