Title: Mechanical Properties of High-Strength Fiber Reinforced Concrete

Publication: Materials Journal

Abstract:A total of 504 concrete specimens are tested to study the effect of including hooked-end steel fiber reinforcement on the mechanical properties of high-strength fiber reinforced concrete. Fiber content ranges from zero to 1.5 percent by volume, and the concrete matrix compressive strength is about 94.0 MPa (13,500 psi). The influence of fiber content on the compressive strength, modulus of rupture, toughness, and splitting tensile strength is presented. Addition of 1.5 percent by volume of hooked-end steel fibers resulted in a small increase (4.6 percent) in the compressive strength, while the modulus of rupture and the splitting tensile strength increased by 67.0 and 159.8 percent, respectively.
