Service-life performance of reinforced concrete structures in corrosive environments

The influence of different sources of uncertainty on the prediction of corrosion initiation, propagation, and corresponding structural damage on results of LCC analysis was investigated in Val (2007). However, not only available statistical data but the predictive models themselves are being updated and improved with time. In particular, major projects such as DuraCrete (2000) and LIFECON (2003), which were completed recently, contributed significantly to understanding of deterioration mechanisms in RC structures and development of new improved models for their prediction, especially it concerns corrosion-induced deterioration. Another important document published lately, which provides models for prediction of corrosion initiation, is fib Model Code for Service Life Design (fib 2006).
