Abstract	Each year the significance of structural rehabilitation in construction industry increases. Throughout the structure’s exploitation period some damages and deteriorations occur, new requirements considering service loads may appear, which makes a structure unfit to present demands. Considering the cost of new construction, in many cases structural rehabilitation of a building is much cheaper and can greatly increase structures estimated service time. In this article we have focused on reinforced concrete jacketing, which is one of the most common strengthening methods for reinforced concrete columns. Twelve column specimens were tested to failure to study strength and durability of jacketed reinforced concrete columns. All specimens had identical geometrical characteristics, material properties and were tested as pinned columns. Before jacketing test specimens were loaded to different levels to determine the influence of prior loading on the Reinforced concrete jacketing proved to be a very effective strengthening method that allowed us to achieve up to 290% of strength increase. Neither interface preparation methods nor adhesive materials were used to increase bonding between the new concrete and the column. Nevertheless, no displacements, cracks or adherence loss between columns and jacketing were noticed. Keywords—reinforced concrete jacketing; columns; strengthening.
