- Abstract
- In this study, the corrosion behaviors of rebar embedded in concrete were measured and compared with those of mixed concrete admixture. In order to observe the corrosion behavior, the impedance of the rebars was measured in a 3.5wt% NaCl solution environment. Using the Bode modulus plot at the measured impedance, the concrete resistance and the polarization resistance of the steel bars were compared and evaluated. As the substitution ratio of blast furnace slag increased, the coating resistance of concrete increased and the polarization resistance increased.
