A study of rebar corrosion using the electrochemical noise (EN) method and strain measurement was performed for corrosion monitoring of reinforced concrete under cyclic accelerated corrosion test. Good agreement was observed between both measurements. They described two phases of corrosion initiation and crack propagation as detected by strains from corrosion-induced fractures, and two phases of passive and active state of corrosion detected by EN measurement. Furthermore, strains could detect the corrosion process, microcracks initiation, surface macrocracks. |
