## Abstract Reinforcement in concrete members is usually protected against corrosion by the alkalinity of the pore solution, but as a result of chloride ingress or carbonation (initiation stage) the reinforcing steel can be depassivated and corrosion can proceed (propagation stage). During the past

✦ Synopsis
During recent years research projects with different approaches have been carried out to develop models which are suitable to assess the metal removal rate in case of reinforcement corrosion. Some of them are based on empirical methods and correlate the corrosion rate to parameters like concrete resistivity, temperature and relative humidity. Another type of model is based on a quantification of the ongoing electrochemical processes. In this paper the theoretical backgrounds and mathematical descriptions of reinforcement corrosion with regard to a numerical modelling are presented and discussed.

Steel corrosion in reinforced concrete structures leads to severe degradation processes which usually affect both the ultimate and serviceability limit state performance of the whole construction. Numerical modelling of such a behaviour requires effective non linear models able to capture all the ma
## Abstract Reinforcement corrosion is the most common reason for the premature deterioration of a concrete structure. In case of a partial depassivation of the reinforcement macrocells are formed with considerable metal removal rates. Thus an assessment of the macrocell current becomes of great co
