Abstract

The passivation behavior of Cr10Mo1corrosion-resistant rebar steel and ordinary HRB400 rebar steel either as bare steels in a Cl^- free simulated concrete pore solution, or as rebar steels embedded in a concrete made of cement and reagent sea-sand in an artificial seawater 3.5% NaCl solution were studied by electrochemical technology and microscopic analysis technology, meanwhile the resistance probe technology was used to establish a rapid evaluation method of rebar corrosion. The results show that the corrosion resistant rebar steel exhibits better passivation behavior in the simulated pore solution with pH 11.5. In the second testing circumstance, the passivation film resistance value of the corrosion-resistant rebar steel is larger than that of the ordinary rebar steel, correspondingly, the corrosion current density of corrosion-resistant rebar steel is also smaller than that of the ordinary one. Results of EDS and XRD characterization show that due to the presence of Cr element, Cr₂O₃ generated by passivation reaction makes corrosion-resistant rebar steel exhibit better corrosion resistance. In order to rapidly evaluate the corrosion behavior of corrosion-resistant rebar steel, the resistance probe method was adopted to assess the corrosion rate of corrosion-resistant rebar steel in the second testing circumstance environment of seawater sand concrete. Consequently, the annual corrosion rate of corrosion-resistant bar steel was acquired to be 0.0047 mm/a. While the corrosion rate acquired by mass loss method dose further confirm that this resistance probe method may suitably be used to rapidly evaluate the corrosion behavior of steel bars within concretes.
