Abstract

Strengthening concrete structures with Fibre Reinforced Polymer (FRP) is one of the most commonly used technique to repair and rehabilitate concrete members due to the advanced properties of FRP over other conventional materials such as steel plates. The required performance of FRP-concrete system is linked to achieve proper bond between FRP and concrete substrates that as exposed to different environmental conditions. In the current paper, a review is conducted to highlight the most reported work by other researchers regarding the bond behavior of concrete members that strengthened with FRP in shear-tension and exposed to temperature-based conditions and compared with ambient conditions. The current review focused on the conducted work on FRP/concrete system that strengthened with two different installation techniques (externally bonding (ES) and near–Surface mounted (NSM)) using two different bonding agents (epoxy-based adhesive (EBA) and cement-based adhesive (CBA)) with and without modification. The adoption of two specific bond test procedures (adhesion and single lap shear tests) at ambient conditions and temperature-based conditions was also reviewed intensively to clarify the advantages and drawbacks associated with each test.  Some reported findings by others in conducting bond test methods for different FRP/concrete systems were highlighted as well to address the gap in knowledge and the need for further research in this regard.
