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.

Shearography applied to the non destructive evaluation of bonded interfaces between concrete and CFRP overlays / Frédéric Taillade in European journal of environmental and civil engineering, Vol. 15 N° 4 (Avril 2011) 

Public ISBD [article]  in European journal of environmental and civil engineering > Vol. 15 N° 4 (Avril 2011) . - pp. 545-556 Titre : Shearography applied to the non destructive evaluation of bonded interfaces between concrete and CFRP overlays : From the laboratory to the field Type de document : texte imprimé Auteurs : Frédéric Taillade, Auteur ; Marc Quiertant, Auteur ; Karim Benzarti, Auteur Année de publication : 2011 Article en page(s) : pp. 545-556 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Non  destructive  testing  Shearography  Disbonds  Concrete  Carbon  epoxy  FRP Index. décimale : 624 Constructions du génie civil et du bâtiment. Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : A shearographic method is proposed that allows (i) to detect bonding defects (delamination or adhesive disbonds) between concrete structures and externally bonded FRP reinforcements, (ii) to assess the width of these defects, and (iii) to evaluate the quality of the adhesive bond in the case of partial delamination, damage or poor properties of the polymer adhesive. The performance of the method is first demonstrated on laboratory specimens containing calibrated defects, i.e., non adherent polytetrafluoroethylene discs placed at the concrete-to-FRP interface. Then, an example of on-site application illustrates the potential of such method for routine inspections of FRP strengthened structures.
