Corrosion-induced deterioration in reinforced concrete structures poses a critical threat to structural integrity and service life. This study investigates the effectiveness of an integrated rehabilitation strategy that combines geometric restoration using high strength, non-shrink grout (Sikagrout 215) with flexural strengthening via externally bonded glass fiber-reinforced polymer (GFRP) composites on beams damaged by simulated corrosion
induced section loss and spalling. An experimental program was conducted on two groups: unstrengthened control beams (NB) and rehabilitated specimens (GFB). Key performance indicators, including ultimate load capacity, loaddeflection response, concrete and steel strain development, and GFRP strain evolution, were systematically analyzed. Results demonstrate that GFRP-strengthened beams achieved a 10.87% higher average
ultimate load (34.64 kN) than sound control beams (31.24 kN). Although the GFRP layer resulted in a slightly lower ultimate concrete strain in GFB (2391 \u00b5\u03b5) compared to NB (2821 \u00b5\u03b5), the rehabilitated beams exhibited enhanced structural resilience, evidenced by a 28.82% increase in yield load and a 25.08% reduction in mid-span deflection at ultimate failure. Furthermore, the failure mode shifted from conventional ductile flexural failure in
control beams to a highly predictable GFRP rupture, without premature shear failure. GFRP strain measurements confirmed full material utilization, with recorded rupture strains of 15,672 and 18,532 \u00b5\u03b5 aligning within an 8% margin of theoretical predictions. These findings validate that the proposed dual-phase rehabilitation approach recovers lost strength while quantitatively enhancing structural resilience and failure predictability, offering a practical, evidence-based solution for extending the service life of aging infrastructure affected by corrosion.<\/p>\n\n\n\n
