In this study, chloride penetration in a repaired concrete using magnesium polymer ceramic (MPC) was assessed based on the NT BUILD 492. To investigate the effect of repaired material on chloride penetration, a cylinder OPC concrete specimen was fabricated and attached on the surface with MPC. Then, chloride penetration test was carried out on the combined concrete sample at a constant applied voltage (30 V) for 6 hours. It was found that most of chloride sources was passed though the interface between OPC and MPC, resulting in a loss of chloride in the material. Thus, it is needed to modify the conventional chloride penetration test for the repaired concrete specimen.
