Abstract

Chloride diffusivity of cement paste was predicted in combination of multiscale fractal model and Maxwell equation. In particular, the multiscale fractal model built up pore structure in cement paste, while the Maxwell equation was used to calculate the associated chloride diffusivity. Parametric analysis of pore structure was carried out through the mercury intrusion porosimetry(MIP) test. The prediction of chloride diffusivity was validated with the rapid chloride migration(RCM) test. The proposed method may be extended to other cementitious systems, which provides a new routine for the prediction of chloride diffusivity.
