The effects of maximum aggregate size on mechanical properties of high-strength steel fiber reinforced concrete (SFRC) were investigated in this work. Test main variable is maximum aggregate size (8 and 20mm). The cylinder specimens was casted for compressive test and the prism specimens was tested under four points loading. Test results indicated that the addition of steel fiber improves compressive and flexural behavior of high-strength concrete. Also smaller aggregate size improve mechanical properties of high fiber volume fraction SFRC.
