| Research Abstract |
The purpose of this study is to predict the transport of ion in the hardened cement paste that calcium leaching occurred quantitatively. Furthermore, the mass transfer prediction model was improved by incorporating the phase equilibrium of solid-liquid interaction and3-dimensional spatial image model. As a result, it is possible to predict the transport of ion by the proposed prediction model. The AC impedance method that is simple and non-destructive measurement was applied to measure the transport properties of hardened cement paste, it is clarified that the relationship between the measured conductivity by AC impedance and diffusion coefficient of hardened cement paste was in good agreement.
