This paper highlights the review of the behavior and strength of strengthening reinforced concrete columns by reinforced concrete jacketing. Even with the fact that on a massive scale, numerous experimental studies on column strengthening with the assistance of reinforced concrete jacketing are performed after which suggested, however, there may be nonetheless an apparent need for locating and executing new approaches to improve the performance of classical RC jacketing. As in the case of RC structure, columns are subjected to uniform and non-stop loading, which increases with the boom in a number of stories and might cause partly damage or even general failure of the column. To overcome the whole failure of RC columns, instant attention is needed in and the broken part of reinforced concrete repaired by way of reinforced concrete jacketing. This paper additionally focuses on the effect of presenting dowel rebar by way of drilling holes and using concrete jackets made with particular types of concrete. The results show that each use of dowel rebar and distinctive kinds of concrete will increase the bond strength, basic load wearing capability, and primary crack load. Critical cases clarified to avoid such as reinforcing limit and form, type and property of concrete, types of surface preparation, and a recommendation for high temperature.
