Distributed Optical Fiber Sensors (DOFS) are gaining interest for structural health monitoring applications. Recently, they have been successfully used to monitor the strain profiles at the interface between concrete and steel or composite rebars during pullout tests. In the framework of durability studies on Glass Fiber-Reinforced Polymer reinforc...
la corrosion des armatures est la principale cause de dégradation des structures en béton armé. L'un des objectifs prioritaires de l'Université Gustave Eiffel porte sur l'amélioration de la durabilité des structures de génie civil avec la volonté de faciliter l'introduction de nouveaux produits et procédés allant dans ce sens. Dans le cadre de diff...

The aim of the present study is to evaluate the biomolecules which can be potentially used as an ecofriendly inhibitor of steel corrosion in concrete. Biomolecules used in this study are a new class of compounds produced from bacteria cells. The inhibition effect in simulated concrete pore solution was demonstrated using classical electrochemical m...

This paper deals with the experimental determination of the bond behaviour between ultra-high performance fiber-reinforced concrete (UHPFRC) and reinforcing bars (rebars). An experimental campaign has been carried out to assess the bond behaviour considering different rebar diameters, different embedment lengths and different concrete covers. A rel...
L'adhérence d'armatures de béton armé dans du BFUP a été caractérisée expérimentalement sur éléments minces et en pleine masse, sous chargement monotone et répété, en s'appuyant sur une instrumentation innovante par fibres optiques. Les résultats confirment une longueur d'ancrage très faible mais augmentant significativement pour de faibles valeurs...
Aramid Fiber Reinforced Polymer (AFRP) rebars are being used as internal reinforcements of concrete structures for more than ten years. Their main advantages over common reinforcing steel rebars rely on their lightness, durability performances, mechanical properties, and electromagnetic neutrality. For this application, interfacial properties betwe...
The bond capacity and characteristic behaviour of steel rebars embedded in ultra-high performance fibre-reinforced concrete (UHPFRC) has been studied. Indeed, sufficient ductility is to be ensured by proper seismic-resistant detailing of reinforced (or fibre-only reinforced) UHPFRC structures. This research is especially important for UHPFRC mixes ...
