Over the last few decades, there have been major advances in the civil engineering sector leading to improved safety, economy and enhanced construction activities. Even though the operational life of concrete structures are constantly being subjected to detrimental effects due to various natural and human imposed phenomena, there is always a need for sustainable improvement in extending the functionality of a building. The significance of Fibre Reinforced Polymer (FRP) rehabilitation has contributed in achieving substantial performance with high strength, light-weight and high stiffness structural fibres which could resist further corrosion. One of the major drawbacks is the application of epoxy resin during the strengthening process resulting in health-related concerns as well as high impact on the surrounding environment. There has been a comprehensive literature analysis undertaken in this paper to investigate the influence of alternate sustainable bonding composites that could potentially replace epoxy thereby not compromising on structural stability and integrity. A discussion based on the literature review reports the necessity of alternate solutions in assimilating the essential sustainable bonder material with appropriate mechanical characteristics. © IAEME Publication.
