A Review on Fiber Reinforced Concrete Structures

Abstract

Progression in cement-based technology has driven the development of fibre reinforced concrete (FRC) materials; such as concrete technology. Steel fibre and synthetic fibre are fundamental fibre types, which include glass, carbon, polyvinyl, polyolefin, waste fibre materials and polypropylene. The mechanical properties of FRC members are affected from these fibres individually and in hybrid aspects. The type, content and geometry of fibres are relied to these mechanical properties. A significant improvement in mechanical and dynamic properties of reinforced concrete members is enabled due to additional fibres into cementitious composites. Most mechanical properties are enhanced through intercept micro-cracks. The level of enhancement accomplished relied on the type and dosage of fibre as compared to plain concrete. Effective tensile strength, energy dissipation capacity and toughness are explained through FRC. The shear, punching and flexure are significantly increased through the level of enhancement accomplished. These fibres include polyvinyl, glass, carbon, polyolefin and polypropylene that improve the mechanical properties of concrete. The historical use of fibres and types of fibres are reported in this chapter. Similarly, the curing of steel, structural synthetic fibres, the mechanical properties of cement, the addition, placing, finishing and mixing are based on waste fibres, hybrid fibres, steel and structural synthetic.
