Plain concrete has a low tensile strength, ductility and little resistance towards splitting. By adding firmly divided and consistently scattered fibers to concrete this splitting can be controlled to a limit and considerably enhances its static and dynamic properties. This paper presents impact on mechanical properties of fiber reinforced concrete, for example, density, workability, compressive strength and split tensile strength. The aspect ratio of the fiber is the proportion of its length to its diameter used. A composite is named as hybrid, if at least two sorts of fibers are soundly joined to create a composite that gets advantage from every one of the individual fibers and shows a synergetic reaction. Cube and cylindrical samples have been outlined with steel fiber reinforced concrete containing fibers of 1.0, 1.5, 2.0% volume division of hooked end steel fibers of 65 and 80 aspect rations. The test outcomes demonstrated that the compressive strength and split tensile strength of HFRC with two diverse aspect rations at same volume fraction demonstrates an improvement. However, inclusion of fiber to the concrete influences the workability of concrete and can be overwhelmed by utilizing super plasticiser. In producing the specimens, the volume content of the fiber was held at 1%,1.5% & 2% (if only one type of fibre is been mixed) and if combination is mixed means the volume fraction is held at 0.5%+0.5%, 0.75%+0.75%& 1%+1%. an improvement was obtained from the hybrid mixes when compared to all the other samples.
