| Research Abstract |
In order to quantitatively evaluate characteristic structures in concrete at different observation levels, spatial statistics such as the second order stereology function were obtained from images. There existed good correlations between the statistics and macroscopic properties of concrete, especially a transport property. Furthermore, taking account of the relationship between the correlations and the pozzolanic reaction, improvement of durability in concrete with blended cements can be explained by discontinuity of fine pores smaller than the resolution.
