Abstract: The research investigates the advantages of using confinement to improve the axial compression load carrying capacity of RCC cylinders using mild steel rings. For this, confinement by Mild steel rings have been done to RCC cylinders to mimic real structural columns which may otherwise have to be discarded due to poor strength performance. The experimental programme included compression load testing a number of RCC cylindrical specimen to establish the effect the confinement had on the compressive load-carrying capacity. Effect of grade of concrete was also investigated in the study. It was found that confinement of RCC Columns increase axial load bearing capacity. The confinement yielded an increase in axial load bearing capacity of Circular RCC Columns by Confinement of Mild Steel Rings is 43.20 % for Fe415 grade of Steel and M25 grade of concrete. The confinement yielded an increase in axial load bearing capacity of Circular RCC Columns by Confinement of Mild Steel Rings is 40.74 % of Fe415 grade of Steel and M20 grade of concrete.
