Abstract

The accelarated deterioration experiment of the specimen which modeled RC lining and SFRC lining with the bending crack was carried out. The corrosion of the reinforcement in ages 30th of the RC lining was measured, and the bending test for confirming performance of structure was carried out.<BR>As the result, It was confirmed that invasion of chloride ions and progress of the carbonationto the crack inside were early by the exsistence of the crack over 0.1mm at the width. The corrosion of the reinforcement started by the infiltration of chloride ions in the crack inside. In the meantime, the dynamic performance of the reinforcement did not lower, even if the reinforcement corroded, ifthe age is 30th.
