Paper Title:
Corrosion Behavior of HRB400 Reinforcing Steel Based on Electrochemical Impedance Spectroscopy
  Abstract

Electrochemical impedance spectroscopy (EIS) technique was used to investigate the corrosion behavior of HRB400 reinforcing steel in Simulated Concrete Pore (SCP) solutions differently contaminated by bicarbonate ions and/or chloride ions. The corrosion kinetics parameters of the capacitance Y0-CPEdl, surface roughness n0-CPEdl and charge transfer resistance Rct of the electric double-layer capacitance of the interface of solution/HRB400 were analyzed and were compared to those of HPB235 reinforcing steel. The results show that the corrosion resistance index of HRB400 and HPB235 is increased with an increase in NaCl content to 0.1%, but that is decreased markedly for a larger NaCl content; and that of them is decreased largely with an increase in pH; the decrease extent of the corrosion resistance index of HRB400 with NaCl or pH is larger than that of HPB235; and the corrosion resistance of HRB400 is inferior to that of HPB235.
