Estimation of Carbonation and Effective Repair Zone in Underground Structure

초록

Reinforced concrete structures are deteriorated in a few decades due to various causes, such as carbonation. Therefore it is important to evaluate the accurate carbonation depth in order to secure the durability of the structure. In this paper, carbonation depth by drilling excavation and splitting core sample are compared. Also, the procedure for estimating the appropriate repair zone is proposed, with the result of carbonation depth and steel bar detection.
