Flexural behavior of GFRP rebars and steel rebars with polypropylene fibers and fly ash-based concrete

Research on Engineering Structures and Materials
Alternative materials are required since steel reinforcement in concrete constructions is prone to rust, which creates durability issues. This study investigates the feasibility of replacing steel reinforcement in concrete applications with glass fiber-reinforced polymer (GFRP) rebars. The experimental work used M30 grade concrete with two mix designs:
