Xu, Auteur ; L. Jiang, Auteur ; F. Xing, Auteur Année de publication : 2011 Article en page(s) : pp. 802–809 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Chloride  threshold  level;  concrete;  inhibitor;  N,N′-dimethylaminoethanol;  steel  reinforcement Résumé : The aim of this study is to examine the influence of N,N′-dimethylaminoethanol (DMEA) as an inhibitor on the chloride threshold level for corrosion of steel in a concrete contaminated by chlorides. The experiment has been carried out in a saturated Ca(OH)2 solution and chloride contaminated concrete containing different chloride and DMEA level. The critical point of corrosion onset is concluded by combining the open-circuit potential (Ecorr) with corrosion current (Icorr), which is decided by electrochemical impedance spectra (EIS) in the solution. Besides, the EIS has also been applied to determinate the chloride threshold level in the chloride contaminated concrete. It has been found that the presence of DMEA represented as an amino-alcohol inhibitor, exerts little influence on the chloride threshold level for corrosion of steel in the solution. Similarly, the effect of the DMEA on the chloride threshold level in the chloride contaminated concrete, is also negligible.
