  A model for corrosion-induced cracking of reinforced concrete subjected to
non-uniform chloride-induced corrosion is presented. The gradual corrosion
initiation of the steel surface is investigated by simulating chloride
transport considering binding. The transport of iron from the steel surface,
its subsequent precipitation into rust, and the associated
precipitation-induced pressure are explicitly modelled. Model results, obtained
through finite element simulations, agree very well with experimental data,
showing significantly improved accuracy over uniform corrosion modelling. The
results obtained from case studies reveal that crack-facilitated transport of
chlorides cannot be neglected, that the size of the anodic region must be
considered, and that precipitate accumulation in pores can take years.
