This study investigated the effect of different steel fibre contents by volume (Vf = 0, 0.5%, 1%, and 1.5%) on mechanical properties of High Strength Fibre Reinforced Concrete (HSFRC). The properties included flowability, compressive strength, and direct tensile strength. The results indicated that increased steel fibre contents gradually decrease the flowability of HSFRC. However, had significant effects at 28 days on compressive strength by about 102.5 M.Pa and direct tensile strength by about 7.07 M.Pa of HSFRC with incorporation of 0.5% steel fibre. While, the compressive strength of 1.0% and 1.5% of steel fibre contents are 87.51 M.Pa and 80.75 M.Pa, respectively, whereas direct tensile strength with 1% and 1.5% of steel fibres achieved 6.54 M.Pa and 5.66 M.Pa. The result shows the higher compressive strength and direct tensile strength obtained by 0.5% of steel fibre content. The value of direct tensile strength close to JSCE 2004, over 5 M. Pa
