Bonding behaviour of epoxy resin over mineral composite in FRP retrofit

The importance of rehabilitation of deteriorated concrete structures is rapidly gaining popularity due to various factors. In recent years, the Fibre Reinforced Polymer (FRP) become widely used in structural strengthening and retrofit due to its merits. While epoxy resin is widely used as a binder in the FRP strengthening, it also has some health-related demerits. The primary objective of this project is the experimental investigation in using a sustainable Mineral Based Composite (MBC) as a potential replacement for the epoxy during FRP retrofit. The retrofit normally is done either using FRP strips or wraps. The research methodology involves a single wrap of three independent FRP materials around the damaged concrete surface with both epoxy and the mineral based bonders and test for its mechanical properties. The results obtained indicate that the proposed MBC bonder had comparable behaviour in regards to FRP retrofit as like epoxy.
