Larsena, Auteur Année de publication : 2010 Article en page(s) : pp. 1122-1138 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Corrosion;  Durability;  Chloride;  Reinforcement Index. décimale : 691 Matériaux de construction. Pièces et parties composantes Résumé : Chloride induced corrosion as the major cause for degradation of reinforced concrete has been the subject of great research efforts over the last fifty years. The present literature review summarises the state of the art by presenting the concept of the critical chloride content, discussing influencing factors, and assessing available measurement techniques. A large number of published chloride threshold values together with the respective experimental details are collected. While today's experience is mostly based on Portland cement, more modern studies with non-traditional binders often reported contradictory results. The present literature evaluation highlights the strong need for a practice-related test method, and, in this regard, focuses especially on experimental procedures by discussing advantages and drawbacks of methods and setups. It clearly emerges that many of the setups used to determine critical chloride contents are not suited to give realistic results.
