Effect of corrosion on bond strength of steel and non-metallic reinforcement / S. Demis in Materials and corrosion, Vol. 61 N° 4 (Avril 2010) 

Public ISBD [article]  in Materials and corrosion > Vol. 61 N° 4 (Avril 2010) . - pp. 328–331 Titre : Effect of corrosion on bond strength of steel and non-metallic reinforcement Type de document : texte imprimé Auteurs : S. Demis, Auteur ; K. Pilakoutas, Auteur ; Ch. Alk. Apostolopoulos, Auteur Année de publication : 2010 Article en page(s) : pp. 328–331 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : accelerated  carbonation;  bond  strength;  corrosion;  fiber  reinforced  polymers Résumé : Research attempts on the effect of environmental corrosion on bond between steel bars and concrete, report considerable losses of bond strength. Alternative solutions to the corrosion problem include the use of non-metallic reinforcement. In this paper the effects of environmental corrosion (through accelerated carbonation) on the bond properties of fiber reinforced polymer (FRP) bars with the surrounding concrete are investigated. The work presented is part of an extensive project addressing the durability of FRP in concrete 1. It was found out that, in contrast to what is generally believed, concrete alkalinity does not have a major impact on the durability of FRP bar and its bond strength. The expected bond deterioration due to carbonation is more than compensated by the increase in compressive strength due to time and carbonation, contrary to the case when steel reinforcement is used.
