ABSTRACT

Concrete structures are prone to various types of damage over time, including compressive damage, high-temperature fire damage, freeze-thaw damage, and seismic damage. These damages directly affect the safety and durability of concrete structures and may even lead to structural failure. Traditional strengthening methods, such as steel reinforcement or steel plate bonding, increase the structural weight and introduce construction challenges. Additionally, materials used in these methods are prone to corrosion, which is difficult to control. In contrast, the recently developed Basalt Fiber Reinforced Polymer (BFRP) strengthening method offers high strength, excellent corrosion resistance, and lightweight properties, making it an ideal solution for repairing and strengthening concrete structures. This paper summarizes the strengthening mechanisms and effects of BFRP on concrete structures subjected to compressive damage, high-temperature fire damage, freeze-thaw damage, and seismic damage. It also briefly discusses current research limitations and future directions.
