A series of tests was conducted to determine the structural properties of High Strength Concrete (HSC) such as cube strength, cylinder strength, split tensile strength, modulus of rupture, modulus of elasticity and Poisson's ratio. The test results of HSC of strength grade M85 (85MPa) were then compared with normal strength (M35) and moderately strength (M65) concrete. The fibre content was varied from 0.0 to 1.5 percent by volume of concrete at 0.5 percent interval. The improvements in various strength properties due to the addition of fibres were assessed and empirical strength models were developed based on regression analysis. The prediction models show close agreement with the experimental data. It is expected that these models will give some useful insights in assessing the quantity of steel fibres need to be added to achieve the desired strength and deformation characteristics for various strength grades of concrete.
