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 few years numerous research activities have been carried outβ€”mainly by laboratory experimentsβ€”to investigate reinforcement corrosion. Another approach, which will be presented within this paper, is given by using the finite or boundary element method. The results of the simulations will be compared to measurements and used to investigate the impact of single parameters.

In the recent past, the damage caused by rebar corrosion in concrete structures has been considered as one of the major durability problems affecting the service life of concrete structures. In order to prevent corrosion of steel reinforcement, various types of protective methods have been adopted.

## Abstract The corrosion of steel reinforcement in concrete structures induced by chloride ion contamination is a major problem. Deterioration starts with the loss of protection provided by the concrete cover as the result of chloride ingress. This is followed by corrosion initiation and then prop
