Reinforcement of concrete by composite materials
Renforcement du béton par les matériaux composites
Université Hassiba Benbouali de Chlef, Algérie
This work was devoted to the material-scale study of the mechanical behavior of confined concrete by composite materials based on carbon fiber and glass under compression and bending loading. In this context, an experimental work on cylindrical and prismatic concrete specimens has been carried out. The obtained results permitted the identification of the mechanical behavior, strength, deformability and failure modes. The outcome of the present research indicates an increase in the bearing capacity and deformability in compression and in tension. The reinforcement by means of composite materials appears as a pertinent solution and therefore, makes it possible to obtain clear indication on the type of confinement to be considered according to the intended purpose.
Résumé
Ce travail a été consacré à l'étude à l'échelle du matériau du comportement mécanique du béton confiné par des matériaux composites à base de fibres de carbone et de verre sous un chargement de compression et flexion. Dans ce sens, un travail expérimental sur des spécimens en béton de forme cylindrique et prismatique a été réalisé. Les résultats expérimentaux ont permis l'identification comportement mécanique, des résistances mécaniques et la déformabilité et les modes de rupture. Pour l'ensemble des résultats obtenus, on a pu constater un accroissement de la capacité portante et de la déformabilité rn compression et en traction, Le renforcement par les matériaux composite est une solution fiable pour le renforcement et permet de dégager des indications claires sur le confinement à adopter selon l'objectif visé.
