A Comprehensive Review of Advanced Retrofitting Materials and Techniques of RCC Structures

The service life of any infrastructure can typically range from 60 to 70 years. However, proper design may enhance the duration of serviceability. Sometimes, infrastructures may sustain damage due to natural hazards, seismic loads, or other unforeseen factors that may degrade the durability and serviceability of infrastructures within the life span. This would become very difficult to renovate that infrastructure. Regarding this inconvenience, the term ‘Retrofitting Techniques’ appears to overcome this problem. Despite structural damage, a retrofit can easily or effectively restore structural integrity and enhance durability. This technique also can enhance the life span of damaged infrastructures. Advanced materials such as fiber-reinforced polymers enhance the strength and durability of retrofitted structures. Aging effects such as deterioration of materials and fatigue failure may degrade the structural integrity. However, retrofit can restore this problem. This modern technique of upgrading the existing structures may enhance the strength of RCC structures. This study will highlight a comprehensive overview of retrofitting to enhance the structural integrity, safety, and durability of existing structures.
