This paper describes the effect of tensile strength and aspect ratio of fiber on compressive and flexural toughness index of high- and normal-strength steel fiber-reinforced concrete(SFRC). For this purpose, eight types of SFRC mixtures were made and tested. Test results indicate that the compressive and flexural toughness index of SFRC increased with increasing in tensile strength and aspect ratio of steel fiber.
