Abstract

High strength concrete (HSC) is defined as concrete with a specified compressive strength of 40 MPa or greater. Concrete with high strength is basically a brittle material, with low tensile strength. One way to improve the brittle and weak concrete properties towards tensile strength is by utilizing fiber. The utilization of steel fiber from waste tires (SFWT) in high strength concrete can be used as an alternative to improve the mechanical properties of the concrete and also has benefit to reduce the waste of used tiresthat are increasingevery year. This research was conducted to determine the effect of the addition of SFWT on HSC and high strength concrete containing silica fume (HSCSF). The SFWTis obtained from the extracting of used tires that are cut into 4 cm long. The specimen used is a cylinder with a diameter 15 cm, height 30 cm and beam with dimension 10x10x50 cm. The content of silica fume on HSC is 10% by replacing the cement weight. The addition of SFWT in both HSC and HSCSF are 0%, 0.5%, 1.0%, 1.5%, and 2%. Mechanical properties of concrete such as compressive, tensile,and flexural strengths are tested at 28 days ago. The results show that the addition of SFWT increases the mechanical properties of HSC and HSCSF. The increase of SFWT content results in the higher mechanical properties of the HSC. In addition, the presence of SFWT in the HSC delays the crack width of the concrete and prevents the brittle collapse.
