The effects of using steel fibers on self-compacting concrete properties : a review

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