Background/Objectives: The experimental investigations are carried out to study the behaviour of Glass Fiber Reinforced Polymer (GFRP) sheet not wrapped and wrapped around RC column. Methods/Statistical analysis: Strength of the RC column was assessed by performing compressive and split tensile strength tests at the interval of 7, 14, and 28 days as per code of provision. Findings: In this study, the recycled aggregate has been replaced with the natural aggregate. The replacement percentage was chosen for this study was 10%, 20%, 30%, 40%, and 50%. The compressive strength of partial replacement of recycled coarse aggregates (PRRCA) are found to be higher than the compressive strength of normal concrete. Furthermore, results on load, deflection and failure modes of each of the columns were also obtained. Applications/Improvements: Strength of the damanged concrete structures can be improved after wrapping GFRP sheet over the damaged structures.
