Water transfer behavior in hardened cement paste is evaluated. For evaluation of water transfer, mass loss of specimens over time is measured and Boltzmann's method is applied to measured data. At the same time, desorption isotherm of hardened cement paste is evaluated. Using the diffusion coefficient for nominal water content and desorption isotherm, water conductivity for chemical potential of water in hardened cement paste is derived. Nine hardened cement paste specimens, which have different porosity, are tested and using these data, predicting model of water conductivity is proposed.<br> The proposed model needs the properties of hardened cement, such as, maximum water content at 20°C degree, water vapor BET surface area, and water content for predicting the water conductivity. According to the simulated results, the temperature dependency of water conductivity is obvious. Evaluation of temperature dependency of water conductivity is remained to be future issue.
