ABSTRACT

A method to repair reinforced concrete slabs after fire using near-surface mounted (NSM) carbon fiber reinforced polymer (CFRP) rods is carried out in this study. From experimental databases, it is clear to conclude that the strengthened slabs not only had improved endurance limits but also improved loadcarrying capacities and stiffness values as compared to the unstrengthened slab. Especially, the test results show that slabs strengthened with CFRP rods embedded in repairing material overlay had more load-carrying capacity than slabs strengthened with CFRP rods embedded in concrete or between concrete and repairing material overlay.
