| Research Abstract |
The aim of this research is to reveal the Chloride ion diffusion in unsaturated porous media from the aspect of the porous geometric structure. Capillary absorption method by sea water revealed that Chloride ion cannot diffuse from water seepage front to unsaturated area in case of fly ash concrete. Also, the mechanism of strong mass transfer resistance of fly ash concrete was elucidated by experimental and analytical method about pore structure in concrete.
