Abstract: Cementitious materials are typically characterized as brittle, with low tensile strength and strain capacity. However, with the use of fiber reinforcement, this brittleness can be overcome, producing materials with improved strength, ductility and durability. The development of fiber-reinforced concrete began in the 1960s. Over the past 40 years, significant improvements have been made in the understanding of the role of fiber reinforcement in cementitious materials. The effect of fibers on toughness, fracture behavior, impact performance and composite hybridization has been investigated as well as the role of the fiber-matrix interface. In addition, new high-performance cementitious composites have been developed with superior mechanical performances, exhibiting both an enhanced elastic limit as well as a stain-hardening type of response. Current work investigates the effect that fibers have on the fresh state properties, or rheology, of cementitious materials, so that the fibers can be used efficiently. This paper reviews the advances made in understanding the role of fiber reinforcement in cementitious composites.
