Abstract

Abstract The present research aims to develop green and sustainable corrosion inhibitors based on plant extract. Herein, we have screened the inhibitory performance of Psoralea corylifolia (Badranj Boya) (PCS) seeds in chloride-polluted simulated concrete pore solution (SCPS) for the protection of steel rebar. Electrochemical experiments manifest that PCS can restrain reactions of the cathode and anode of steel rebar. The results reveal that the inhibitory performance magnitude is 95.1 % at 75 mg/L dosing amount after 72 h dipping time. Scanning electron microscopy (SEM) and Atomic force microscopy (AFM) examination support the creation of an inhibitive layer of PCS over the steel rebar surface. Furthermore, adsorbed PCS over the steel rebar was justified via X-ray photoelectron spectroscopy (XPS). Finally, PCS is a green and long-term efficient corrosion inhibitor for concrete structures.
