Abstract: Concrete
structures, although durable, are susceptible to deterioration over time due to
various environmental, mechanical, and chemical factors. The deterioration can
manifest in forms such as cracks, corrosion of reinforcement, and structural
weakening. Rehabilitation of concrete structures is essential for restoring and
extending the lifespan of these structures. This paper reviews the various
rehabilitation techniques available, including surface repairs, injection
methods, strengthening with advanced materials, and cathodic protection. The
study also highlights the criteria for selecting appropriate rehabilitation
methods, the benefits and limitations of each approach, and recent advancements
in rehabilitation technologies.
Keywords: Concrete Rehabilitation, Crack Sealing Techniques, Fiber-Reinforced Polymers (FRP), Cathodic Protection
