염해를 받는 RC구조물의 표면피복재 적용에 따른 LCC평가

Recently it is high interested at the LCC(Life Cycle Cost) evaluation in consideration of the initial measure against the deterioration and the maintenance repair administrative expenses in usable years of the concrete structure. The purpose of this study is that it carries out LCC(Life Cycle Cost) calculation of the RC structure which deteriorated by chloride ion. The surface coating method was applied by the initial measure and the repair method of construction. Repair time of the concrete structure which deteriorated by chloride ion was decided for the time of chloride ion concentration being marginal concentration at location of the reinforcement. It is judged by that selection of the optimal repair method of construction is possible through LCC evaluation.
