Abstract The corrosion resistance of the developed 400 MPa grade rebar was evaluated by a series of experiments, including cycles of corrosion-accelerating tests in the simulated concrete pore solution and reinforced concrete cube corrosion-accelerating tests and in-situ exposure experiments in chloride ions condition. In addition, the tensile and bending properties and the connection adaptability of the developed rebar were investigated. The results verify that the comprehensive properties of the corrosion-resistant rebar are excellent. The tensile and bending properties of the rebar are up to the standard of GB1499-2007. The common welding method and the mechanical connection technology of knob-cut rolled parallel thread splicing are suitable for the rebar.
