abstract
Deterministic forecast of corrosion damage progression in a reinforced concrete column was implemented in a one-dimensional model accounting for potential dependence of corrosion threshold, and macrocell coupling during the initiation and propagation stages. The damage projection was clearly sensitive to the choice of the activation zone size. The relative sensitivity became greater as the zone size decreased. Criteria for selection of this parameter need to be developed. The projected corrosion damage was significantly lowered when threshold dependence on potential was introduced, compared with a fixed threshold case. The damage projection was clearly sensitive to the choice of the activation zone size. The relative sensitivity became greater as the zone size decreased. Criteria for selection of this parameter are being developed. © 2009 by NACE International.
