The Effects of Using Steel Fibers on Self-Compacting Concrete Properties: A Review

Abstract

In this literature review steel fibers reinforced self-compacting concrete properties in fresh and hardened states and factors effecting on them were studied. In spite of high workability of self- compacting concrete, using of steel fibers depending on their length, aspect ratio, shapes and volume fraction can cause detrimental effects on it. Using of steel fibers improves hardened properties especially flexural and post peak performance, and this improvement depends on how fibers can distribute and orientate in fresh state. The better hardened properties can obtain when fibers aligned and orientated in the direction parallel to tensile stress.
