Abstract


A recent research came up with the conclusion that water penetration front is the key issue regarding surface quality which dramatically change the service life as well as life cycle cost of RC structure. In this study, chloride ion profile was measured using cores taken from real structures situated in Hokkaido and samples from Miyazaki Linear Experiment Line, Daidogawa and from a tunnel structure. The samples were put into 10% NaCl solution in the laboratory to get Cl- profile. Using the concept of inclusion of water front in the estimation of chloride profile, the samples from the inspected structures were analyzed. Based on this analysis durability design and LCC comparison among the structures are presented.
