Influence of accelerated corrosion on the reinforced cover concrete cracking behavior / Benjamin Richard in European journal of environmental and civil engineering, Vol. 16 N° 3-4 (Mars/Avril 2012) 

Public ISBD [article]  in European journal of environmental and civil engineering > Vol. 16 N° 3-4 (Mars/Avril 2012) . - pp. 450-459 Titre : Influence of accelerated corrosion on the reinforced cover concrete cracking behavior : Experimental and numerical study Type de document : texte imprimé Auteurs : Benjamin Richard, Auteur ; Marc Quiertant, Auteur ; Véronique Bouteiller, Auteur Année de publication : 2012 Article en page(s) : pp. 450-459 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Reinforced  concrete  Corrosion  Corrosion  modeling  Electrochemical  tests Résumé : This article aims to present both experimental and numerical studies of the corrosion induced cracking pattern evolution of a reinforced concrete sample subjected to accelerated corrosion. The beam was not mechanically loaded. Rebars were intentiostatically corroded using a current density of 100μA/cm² of steel, in a chloride pond and for a 30 day period. Electrochemical tests and visual inspections were carried out in order to characterise the rebar state. Width evolution of the main longitudinal cover crack was measured thanks to ball-extensometer. A numerical modeling of the corroded RC beam has also been realised. The experimental and numerical results are in good agreement confirming the efficiency of the proposed modelling.

Influence of humidity and temperature on the corrosion of reinforced concrete prisms / Véronique Bouteiller in European journal of environmental and civil engineering, Vol. 16 N° 3-4 (Mars/Avril 2012) 

Public ISBD [article]  in European journal of environmental and civil engineering > Vol. 16 N° 3-4 (Mars/Avril 2012) . - pp. 471-480 Titre : Influence of humidity and temperature on the corrosion of reinforced concrete prisms Type de document : texte imprimé Auteurs : Véronique Bouteiller, Auteur ; Jean-François Cherrier, Auteur ; Valérie L'Hostis, Auteur Année de publication : 2012 Article en page(s) : pp. 471-480 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Reinforced  concrete  corrosion  Electrochemical  measurements  Chlorides  Carbonation  Temperature  Humidity Résumé : Reinforcement corrosion is one of the major durability problems that need to be solved in order to extend the service life of a structure. It is influenced, on one hand, by the concrete itself, sound or polluted (chlorinated or carbonated), and on the other hand, by the environmental conditions (controlled or outdoor). To explore the influence of temperature and humidity, electrochemical characterisations (potential, linear polarisation resistance and corrosion rate) were carried out on reinforced concrete prisms. A database of more than 3000 values has been delivered. The results enabled us to deduce that both parameters have influences on each other. Moreover, considering the four concretes, the corrosion order obtained in controlled conditions may be different from the one obtained in outdoor conditions.
