Abstract

An experimental study was conducted on High-Strength Flowable Mortar (HSFM) reinforced at different percentages of steel fiber (0, 0.25, 0.5, 0.75, 1.0, 1.25, 1.5, 1.75 and 2.0% as volumetric fractions) to determine the density, compressive strength, static modulus of elasticity and flexural strength. The load-deflection curves under a static flexural load were established, and the flexural toughness indices were obtained in accordance with ASTM C1018. The results indicate that by increasing the fiber content up to 1.75%, the flexural strength and toughness indices are increased. The density, compressive strength and static modulus of elasticity also increased using steel fiber.
