When steel fibers are added to concrete mix, the tensile and shear resistance of the traditional fiber reinforced concrete are known to be enhanced. However, fibers are also known to impede workability of plain concrete. To improve the workability, Self-Consolidating Fiber Reinforced Concrete (SCFRC) mixes were developed in this study for application in prestressed concrete beams. Extensive fresh and hardened properties of traditional fiber reinforced concrete and SCFRC mixes produced using two different types and variable amounts of hooked steel fibers are presented in this paper. The SCFRC mixes demonstrated satisfactory workability and stability up to a fiber-factor of 55. In general, SCFRC mixes proved to have greater normalized tensile strength than the traditional fibrous concrete mixes for the same fiber-factor. The optimum fiber content was found to be governed by workability requirements of the concrete mix. Keywords: steel fiber reinforced concrete, self-consolidating concrete, self-consolidating fiber reinforced concrete, fresh properties, workability, hardened properties.
