Abstract

To evaluate progress of the rebar corrosion in the RC structure quantitatively, the change with time of corrosion rate of a rebar in concrete is measured by the corrosion rate monitoring using the Tafel extrapolation method and the small size embedded sensor. As a result, using the prediction model of the corrosion rate from result of the measurement, the measurement from the middle of in-service period can estimate corrosion mass loss with around ±20% of real corrosion mass loss.
