摘要：

The relationship between microcell corrosion and macrocell corrosion of reinforcing steel embedded in chloride-free or contaminated concrete was investigated by comparing and analyzing the polarization curve and corrosion rate. The results indicated that the anodic/ cathodic polarization curve of reinforcing steel in the microcell corrosion state could be used to predict the macrocell polarization behavior of cathodic steel or anodic steel in the macrocell corrosion state. There was a good relationship between macrocell and microcell corrosion current density, which was affected by the initial surface condition of steel. This relationship could provide a theoretical basis for predicting the magnitude of the macrocell corrosion rate from the calculated value of the microcell corrosion rate
