Research Abstract

The aim of this study was to establish an analytical model taking into account the interaction between micro-cracking and moisture transfer properties as a part of development of durability prediction method for building wall. It was investigated that the interaction under freezing-thawing process based on the result of gamma-ray irradiation experiment and analytical result by using three-phase equilibrium heat and moisture transfer equation.
