Investigation of uniaxial tensile and compressive behavior of SFRC
Civil engineers are concentrating on producing several alternatives and additives for obtaining High Strength Concrete (HSC) and Normal strength concrete (NSC). As the building grows, so does the technology employed for it. One such substance that excels at preventing early cracks and so raising the concrete’s strength is steel fiber. It prevents early cracks and boosts the strength of the concrete. To achieve the desired strength of 30 MPa and 70 MPa by casting the cubical specimens, this work uses crimped steel fiber with a 0.35 mm diameter at various volumes of 0%, 0.5%, 1%, and 1.5% in combination with Conplast SP430 superplasticizer. For 0–1.5% volume fraction of steel fiber, it is discovered that the compressive strength varies from 44.3 to 60.5 N/mm2 in the M30 mix and from 78.17 to 91.9 N/mm2 in the M70 HSC mix. In terms of the fiber dose for NSC and HSC, the splitting tensile strength of concrete is substantially higher than uniaxial strength. Traditional Steel Fiber-Reinforced Concrete (SFRC) had fracture energy independent of specimen size. The tensile strength of the steel fibers employed in the steel (Fiber-Reinforced Concrete) FRC with HSC and NSC composite determines the fractured energy. According to the results, the softening behavior (tension) that follows from an increase in fiber dose also increases fractured energy.
