| چکیده | ||
| Corrosion of steel reinforcement in reinforced concrete (RC) structures causes an appreciable loss of mechanical properties, which subsequently affects load-carrying capacity, durability, and structural safety. More than 63 scientific papers, including experimental, field based and computational, investigations on the behavior of corroded Reinforced Concrete beams, slabs, and columns strengthened with high-performance materials published between 2003 to 2024 are critically examined in the present study. Engineered Cementitious Composites (ECC), Ultra high-Performance Concrete (UHPC), Fibre reinforced polymers (FRP), and Hybrid systems are the major categories to which the examined methods belong. FRP-based methods such as CFRP laminates, NSM reinforcements, and jackets significantly enhanced flexural and shear strength. Although hybrid methods such as Impressed Current Cathodic Protection-Structural Strengthening (ICCP-SS) and Cementitious Fiber Reinforced Composite Material (C-FRCM) systems provided advantages for both mechanical and corrosion protection, UHPC overlays and ECC wraps improved ductility, crack control, and durability. Finite element modeling and parametric studies validated such enhancements with predictive precision. In spite of these advances, problems like interface debonding, long-term performance under combined corrosion-loading conditions, and absence of standard retrofit design codes continue to exist. This review identifies research gaps in cyclic behavior under environmental stressors, long-term performance modelling, and cost-efficient hybrid solutions. Future studies are suggested to aim at evolving multi-functional, long-lasting, and sustainable strengthening approaches complemented by advanced simulation and monitoring technologies. | ||
