Abstract:
The failure process of epoxy-coated rebars under different magnitudes of loads in simulated concrete pore solution with chloride ions was studied by electrochemical impedance spectrum(EIS)technology.The results showed that coating resistance of the sample under load declined, and water absorption increased obviously.The higher the load was, the faster the failure of the sample would be.The coating water absorption test result was consistent with that of EIS.In addition, the applied load made the coating adhesion of the sample decline, and the adhesion decreased more obviously under a higher load.Therefore, the increase of coating porosity and the decrease of coating adhesion under applied load were the main reasons leading to the degradation of coating protective performance.
