要旨 This study was carried out in order to observe the penetration profile of the chloride ions through cracks in reinforced concrete structures. Concentration and penetration depth profile of Cl- ions might be useful information to consider degradation of life span of structures due to localized corrosion where a crack exists. EPMA and Colorimetric tests were conducted on specimens exposed to NaCl solution under different exposure conditions. The increase of w/c leads obvious dilation on ingression rate of Cl-ions bot only from exposed surface but also around the crack. In general, the penetration depth around crack is higher than that from exposed surface except for those with very low w/c of 0.25.
