Abstract
The corrosion of reinforced steel in concrete in 3.5 % NaCl without and with Prosopis juliflora extract at different time intervals has been studied using various techniques including electrochemical impedance spectroscopy (EIS), potentiodynamic polarization study (PDS) and atomic force microscopy (AFM). The results obtained by electrochemical measurements (EIS and PDS) showed that the extract inhibited corrosion by forming a protective layer on the surface of the embedded steel and by altering the reactions of the cathodic and anodic sites of the steel. Further, the AFM images supported the formation of the protective layer over the surface of the embedded steel by inhibitor molecules. The adsorption of the inhibitor molecules over the surface of the embedded steel obeyed the Temkin isotherm. Density functional theory (DFT) calculations for major ingredients of the extract have been carried out. From the results of the DFT calculations, the influence of major ingredients on the anti–corrosion potential of the plant extract has been correlated. The mechanism of inhibitive action of the P. juliflora extract has also been proposed.
