AB  - Transport of corrosion products into pores and cracks in concrete must be considered when predicting corrosion induced cracking in reinforced concrete structures, since this transport significantly delays the onset of cracking and spalling by reducing the amount radial displacement displacement imposed on the concrete at the steel/concrete interface. We aim to model this process bymeansofatransport-structuralapproach,wherebythetransportpartisdrivenbyapressuregradient generatedbythevolumetricexpansionduetothetransformationofsteelintocorrosionproducts. This pressure driven transport was introduced in an analytical axisymmetric thickwalled cylinder model and a numerical network approach. The influence of cracking and permeability on corrosion induced cracking process with increasing inner displacement is investigated with these two approaches.
