摘要：

It is known that stray direct current can cause corrosive damage over time to bar reinforced concrete, but knowledge on the consequences to steel fibre reinforced concrete is limited. This paper presents analyses and corresponding results from an experimental program (parametric study) investigating the conditions required for current to be picked up by embedded steel fibres or reinforcement (rebars). The experiments showed that there is a clear 'length effect' related to the susceptibility of stray current being picked up by embedded steel (fibres or rebars): the shorter the reinforcement, the larger potential gradient between anode and cathode is required.
