This paper reports the results of an experimental investigation on the behaviour of High Strength Concrete (HSC) reinforced with different types of steel fibre (copper-coated micro steel fibres, deformed macro steel fibre and hybrid steel fibre). A total of 40 cylindrical specimens with 100 mm diameter and 200 mm height were cast and tested for compressive and split tensile strengths. Three groups of steel fibre reinforced HSC specimens were prepared. The first group included 2, 3, and 4% by volume of copper-coated micro (CM) steel fibre; the second group included 1, 2 and 3% by volume of deformed macro (DM) steel fibre; and the third group included 1.5% (1% CM + 0.5% DM), 2.5% (1.5% CM + 1% DM), and 3.5% (2% CM + 1.5% DM) by volume of hybrid (H) steel fibre. Plain HSC specimens without steel fibre were also prepared. The experimental results showed higher improvements in the compressive and split tensile strengths of the HSC with the inclusion of 3, 2, and 2.5% by volume of CM, DM and H steel fibres, respectively, compared to the plain HSC.
