| Abstract: | According to the theory of small angle X ray scattering, a parameter called shape factor was studied to describe degree of anisotropy of micropores in cement paste. The results show that the pores are almost spherical in shape. The effects of the content of silica fume and the ratio of water cement on shape factors are remarkable. Correlations between strengths and micropore shape factor have been found. |
| Keywords: | small angle X ray scattering hardened cement paste shape factor silica fume strength |
