The current practice of repair and retrofit with textiles made up of high-quality yarns such as glass and carbon is based on bonding or wrapping the relevant component with the textile and impregnating it with polymer using hand lay-up technology. Retrofitting with textile-reinforced concrete (TRC) has been evaluated also for use in masonry structures. To avoid such failure and mobilize additional TRC layers for reinforcement, it was necessary to provide mechanical bonding by anchorage. The performance of the strengthening with TRC should also be assessed from the point of view of enhanced durability performance. The damaged specimens were wrapped with TRC or fiber-reinforced polymer (FRP) and loaded again in compression to determine the load-deformation behavior. Although buckling was not prevented in the retrofitted columns, the confinement, carbon-fiber-reinforced polymer (CFRP) as well as TRC, provides a significant delay, ranging from three to seven loading cycles.
