This paper described the correlation between compressive and flexural toughness of SFRC(Steel fiber reinforced concrete). Experiment was conducted to evaluate the correlation SFRC specimens with different aggregate sizes (8mm, 13mm, 20mm) and fiber volume fraction (0%, 0.5%, 1.0%, 1.5%, 2.0%). For the measurement of compressive and flexural toughness using ACI committee and ASTM C 1018 procedure. Test results indicated that the addition of steel fiber improves flexural and compressive performance of high-strength concrete. Also smaller aggregate size improve the mechanical properties of high fiber volume fraction SFRC.
