✦ Synopsis

In 2000 a proposal was launched to install a new Task Group of Working Party 11 of the European Federation of Corrosion, EFC, on modelling of reinforcement corrosion in concrete. Whereas the initiation stage of corrosion, i.e. chloride ingress and carbonation, has received considerable attention during recent years, actually little work has been performed on the propagation stage. The corrosion models currently available on propagation are essentially empirical and do not address the electrochemical nature of the corrosion process. Although empirical models may provide a convenient tool for structural engineers to roughly predict service life of structures during the design stage, these models are considered less appropriate for evaluating specific practical cases. However, a useful application of electrochemical models requires a basic understanding of the underlying mechanisms. In this article information on the activities of the EFC Task Group on Modelling of Reinforcement Corrosion will be highlighted.

The Task Group, chaired by Michael Raupach and Joost Gulikers, organised 4 meetings (Aachen, Luxembourg, Granada and Utrecht) to discuss its major activities in order to arrive at a common approach that could be applied on a number of situations of practical relevance.

The working program included the elaboration of 3 practical case studies by researchers working in the field of reinforcement corrosion. A number of researchers contributed to the activities of the
