This paper presents the findings of an experimental investigation of the mechanical properties of concrete containing steel fibre. In the experimental investigation, the properties of steel fibre used in high strength concrete were assessed through 3 different mixes. Steel fibre was added into concrete in percentages of 0% (control), 0.6%, and 1.8%. These different types of mixes were then tested after durations of 3 days, 7 days, 14 days, and 28 days. Three cube specimens and three prism specimens were prepared for each test. In total, 36 cubes specimens and 36 prisms specimens were prepared and tested. The following tests were performed: workability test (slump test), density test, ultrasonic pulse velocity test, compressive strength test, flexural test, and water absorption test. The experimental results of this study indicate that the inclusion of steel fibres in concrete enhances the mechanical properties of high performance concrete and could reduce the severity of cracking problems for normal and high-rise buildings.
