Abstract
An experiment on artificially accelerated corrosion of reinforcing bars in reinforced concrete beams was carried out. The actual corrosion of the reinforcing bars was obtained after crushing the beams. The accelerated corrosion electrical circuit was analysed and simplified as a series–parallel circuit, the feasibility of which was verified by the calculated and actual current density in the reinforcing bars. Finally, curve fitting of the test data was carried out to modify an equation based on Faraday's law, which can be used to describe the relationship between current density and corrosion ratio during accelerated corrosion. The modified equation was found to be effective when verified against data from other experiments.
