The chloride ion migration coefficient of polymer modified cement mortar (PCM) used as patching repair materials to the deteriorated RC structure was tested by NT BUILD 492 method. To evaluate performance of repaired section against incoming Chloride Ion, 2D-numerical analysis model (FEM) was developed. The diffusion coefficient of chloride ion decreased in proportion to the polymer cement ratio. It became clear through the analysis of FEM model that the performance change over time after repair depend on the removal range of retrograded concrete and the time of repair application.
