Recently, numerical methods that can reliably predict the service life of reinforced concrete structureshave attracted increasing attention. In this, the second of two companion papers, relevant literature onnumerical modeling of steel corrosion is first reviewed. Then, a unified and straight-forward algorithmthat is capable of performing different types of steel corrosion modeling using a single scheme ispresented, based on the new inverse relation relating the current density with potential for the cathodicreaction proposed in the companion paper. Besides being significantly more efficient computationallyarising from the selective mesh refinement feature of adaptive finite element modeling, the proposedalgorithm can also efficiently model complex geometries and incorporate parameters that vary over thedomain.
