ELECTROCHEMICAL STUDY ON THE REINFORCED CONCRETE DURING CURING
钢筋混凝土养护过程中的电化学行为

The electrochemical characteristics of reinforcement concrete during curing time have been investigated by using electrochemical impedance spectrum (EIS) . The differences of the characteristics between the concretes with and without Cl - have been discussed. Two electrochemical equivalent circuits have been proposed by fitting the experiment results, which have been used to explain the corrosion mechanism of rebars in the reinforcement concrete successfully.
