Abstract

Glass fiber reinforced polymer (GFRP) rebars offer a durable alternative to steel in harsh environments. This study assesses a fast repair method for partially damaged recycled aggregate geopolymer concrete (RAGC) elements with GFRP reinforcement. It compares 9 repaired elements combining experimental techniques and finite element analysis (FEA). The rapid repair involves carbon fiber-reinforced polymer (CFRP) wraps. The research examines how exterior CFRP confinement affects failure modes, ultimate axial load, and axial deflection. FEA samples predict axial behavior accurately. Both experimental and FEA results consistently show that the rapid repair method significantly restores ultimate axial load and axial deflection capacities in pre-damaged RAGC elements.
