| Abstract | The corrosion inhibition effect and mechanism of D-sodium gluconate for reinforcing steel in the simulated concrete pore solution containing Cl-were studied by electrochemical techniques, including corrosion potential, potentiodynamic polarization, and electrochemical impedance spectroscopy measurements. The results indicate that 0.01 M D-sodium gluconate showed a good corrosion inhibition effect on reinforcing steel in the simulated concrete pore solution containing 0.1 M NaCl because it strongly hindered the anodic reactions. The inhibition mechanism could be explained on the basis of the competitive adsorption between gluconate anions and chloride ions on the reinforcing steel surface. And D-sodium gluconate could eventually form a compact adsorptive film by strong chelation and effectively inhibit the initiation of reinforcing steel corrosion. |
