The purpose of this study is to understand quantitative prperties of internal condensation in porous material. In winter, water vapor is generally supplied from the interior side of a roof slab and the condensed water accumulated at this side, causes difficulties. In this paper the moisture behavior in this process is dealt with. Firstly the properties of materials concerned with moisture transfer are discussed. Next the experiment and the analysis of the condensation and re-evaporation process are discussed. And the effects of variations in properties on the analysis is also discussed. Consequently, the validity of the application of the simultaneous heat and moisture transfer equation to the analysis of the internal moisture content is shown. Finally it is proved that the variance of material properties effects on the results of the internal moisture content calculation to a large degree.
