Résumé / Abstract
The use of composite reinforcing bars (rebars) for the reinforcement of concrete appears as an attractive solution to prevent corrosion, which is the main pathology encountered on concrete structures. Although such rebars are being used for more than ten years, there is a clear lack of knowledge regarding their durability, especially under alkaline environment.
This paper aims at investigating the evolutions of tensile properties and bond in concrete of GFRP (Glass Fiber Reinforced Polymer) bars under accelerated laboratory environmental conditions. Both plain rebars and rebars embedded in concrete specimens were exposed to these conditions, in order to assess the influence of the alkaline environment. GFRP rebars were chosen for this study, as this type of bars is considered as the most economically competitive solution in comparison with classical steel rebar.
