Mechanical Properties of Normal to High-Strength Steel Fiber-Reinforced Concrete



A total of 84 specimens were tested to study the effect of concrete strength on the mechanical properties of concrete reinforced with randomly distributed steel fibers. The concrete strengths investigated include 25 MPa for normal-strength (NSC), 50 MPa for medium-strength (MSC), and 69 MPa representing high-strength concrete (HSC). Fiber content ranges from 0 to 1.5% by volume of the concrete matrix. The influence of concrete strength on the compressive strength, splitting tensile strength, and modulus of rupture of steel fiber-reinforced concrete (FRC) is presented. Based on the limited number of specimens tested, it was concluded that HSC provides considerable improvement in compressive strength for fiber content of up to 1% compared to that of NSC and MSC. Also, modulus of rupture of NSFRC considerably improves due to fiber compared to those of MSFRC and HSFRC. Splitting tensile strength results do not indicate a clear dependency to concrete compressive strength.
