Bending Characteristics of Hybrid Fiber Concrete Beams Reinforced with Steel–GFRP Hybrid Rebars

Buildings
The current study aims to investigate the effect of using hybrid bars on the bending characteristics of hybrid fiber-reinforced concrete (FRC) beams. For this purpose, a series of flexural tests on FRC beams were conducted. Four FRC beams were fabricated,

Self-healing of concrete cracks by the release of embedded water repellent agents and corrosion inhibitors to reduce the risk for reinforcement corrosion [PDF]

, 2017
From the worldwide steel production, approximately 50 per cent is required to replace corroded steel [1]. In the case of reinforced concrete structures, corrosion of the reinforcement steel causes crack formation and spalling which leads to ...

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:
