Abstract:
Reinforcement corrosion due to chlorides is the most severe deterioration problem in Norway. Structures in a marine environment are most vulnerable. Based on laboratory and field experience, an empirical model for predicting service life of existing structures has been developed. Service life is defined as the initiation period. The present model takes into account the environmental load as well as the improvement over time of the material resistance for chloride ingress. The model is presented and it is illustrated by results from the Shore Approach structure.
