Abstract: 
A physio-chemical model for the simulation of reinforcement corrosion in concrete structures was developed. The model allows for simulation of initiation and subsequent propagation of reinforcement corrosion. Corrosion is assumed to be initiated once a defined critical chloride threshold is reached causing the formation of anodic and cathodic regions along the reinforcement. Critical chloride thresholds, randomly distributed along the reinforcement surface, link the initiation and propagation phase of reinforcement corrosion.

To demonstrate the potential use of the developed model, a numerical example is presented, that illustrates the formation of corrosion cells as well as propagation of corrosion in a reinforced concrete structure.

Keywords: Corrosion, Concrete, Numerical simulation.
