Abstract
In this paper, the quantitative evaluation was carried out on the effect of mix-proportion and material condition on the characteristics (thickness, pore ratio) of transition zone (T. Z.). At first, the thickness of T. Z. was evaluated using Wall-effect Model. Using these values and experimental results (pore volume of T. Z.), the pore ratio of T. Z. can be evaluated. To compare the analytical results with experimental results, prove that the thickness and pore volume of T. Z. that were established from several assumptions was reasonably. Using these results and King's model, the model that calculated the coefficient of mass transport of each phase in hardened cement was established. As a result, the coefficient of mass transport of T. Z. was bigger than that of paste.
