Authors:   Aysha H., Ramsundar K. R., Arun M., Velrajkumar G.
Abstract:  This paper describes the investigations of concrete composite units consisting of two concrete parts.Flexural strengthening of concrete elements by adding new concrete layers is a common strengthening technique. A specific feature of concrete composite structures is the existence of an interface between the component parts which may be the weakest zone in view of the occurring discontinuity of the construction material. It is found that interface preparation and the type of strengthening (tensile or compressive) considerably influence effectiveness. Through a comparison between strengthened and respective monolithic and initial specimens, the efficiency of the strengthening technique is evaluated. This review was aimed at studying the repair materials, repair techniques and test methods for evaluation of bond strength between concrete substrate and repair material.
