Electrochemical study of the corrosion behaviour of steel rebar in a chloride-containing alkaline environment and the passive-film influence mechanism of Xanthium extract
To develop a green corrosion inhibitor suitable for chloride-containing alkaline environments in reinforced concrete, Xanthium extract was investigated in a simulated concrete pore solution (saturated Ca(OH)2 + 3.5 wt% NaCl). Open-circuit potential (OCP), electrochemical impedance spectroscopy (EIS), and potentiodynami...
