Abstract
In this chapter, the various methods employed to repair and restore damaged concrete structures are discussed. Common confinement repair methods include concrete jacketing, fiber-reinforced polymers jacketing, steel plate/sheet jacketing, and ferrocement laminate jacketing. An analysis and critique of current confining methods for repairing damaged concrete are provided in this chapter, along with assessment techniques for evaluating the repairs. A key factor in the efficiency of any repair or strengthening is interfacial performance, which is discussed in detail. A measure of interfacial performance is bond strength, defined as the degree of adhesion between two joined materials or surfaces. Additionally, the chapter emphasizes the importance of ensuring overlay material compatibility with the substrate to prevent premature failure and the achievement of adequate bond strength. Lastly, real-site conditions have been discussed critically, which can improve the assessment effectiveness of various repair techniques.
