ABSTRACT: Concrete brittle fracture and low tensile strength constitute an important durability problem, since they can lead to disastrous damage and failure of the reinforced concrete structures. The improvement of concrete mechanical properties by adding steel fibers to plain concrete is considered as an interesting solution to the problem. This work fits into the continuity of scientific contributions in the field of Steel Fiber Reinforcement Concrete (SFRC). It relies on an experimental study conducted to examine compressive, flexural and abrasion resistance of steel fiber reinforced concrete specimens. The used Steel Fibers (S.F) are curved steel elements with a length to diameter ratio equal to 67. Concrete is made of local materials. The steel fiber contents examined are 0.5%, 1% and 1.5%. The purpose of this research is to investigate the mechanical performances of steel fibers reinforced concrete regarding compressive strength, flexural strength, mechanical abrasion and ductility according to the specimen age. The experimental results show a significant improvement in the mechanical behavior of the SFRC specimens in comparison with plain concrete without reinforcement.
