Investigations of accelerated methods for determination of chloride threshold values for reinforcement corrosion in concrete

Testing the critical chloride content (Ccrit) in laboratory samples or retrieved from structures enhances understanding of rebar corrosion initiation concrete and can result a significant improvement predicting residual service life ageing structures. A possible drawback test methods for Ccrit is that they be time-consuming. In this work, different accelerated testing are studied compared. It found acceleration method influences results. The results discussed with respect to evaluation existing modelling.
