Beam-column joints are considered as the weakest and vulnerable region in the structural system, as they are subjected to high shear forces under seismic action. Hence, the efficacy of the deficient beam-column joint could be retrofitted by various advanced techniques. This study focusses on the efficacy of employing the developed self-flowable cementitious mortar for ferrocement jacketed beam-column joint. A rich self-flowable and high-strength nanosilica-based cementitious mortar is utilized for the ferrocement jacketing techniques. With the intended repair solutions, a series of ten one-fourth scale reinforced concrete exterior beam-column joints that are designed as per IS 456: 2000 was fabricated and tested under simulated cyclic seismic loading. In this study, ferrocement jacketing is employed with two different types of wire mesh confined with durable rich self-flowable cementitious mortar. The performance of the beam-column joint was examined with respect to load-carrying capacity, energy dissipation and ductility. The test results indicated that the developed rich flowable matrices employed for ferrocement jacketed beam-column joint showed an appreciable increase in load-carrying capacity of 40.62% and attained maximum energy-absorption capacity by 14.26%.
