520			_aConcrete is made of chemically active material - cement and volume rigid inclusions - aggregates. Behavior of concrete is expressed by the properties both at fresh and hardened stage. Structural elements are formed using concrete which are subjected to external loads. Since behavior and strength of structural elements are affected by mechanical properties, modification in them is very important for effective performance of structure. Fibers when used in both mono fiber reinforced concrete (MFRC) and hybrid fiber reinforced concrete (HFRC) considerably improve mechanical properties compared to plain concrete. It was reported that MFRC with low modulus fibers result in improved strain capacity, reduced crack width and lesser compressive strength. In the present study, it is intended to evaluate and compare the impact of steel and basalt fibers in mono form and hybrid form in the mechanical properties of high strength concrete. To evaluate the mechanical properties of M40 grade fiber reinforced concrete, volume fractions chosen were 0.25, 0.5, and 0.75 %. Addition of basalt fibers with steel fibers improves synergetic response to a considerable extent. From the overall assessment of the mechanical properties, it was established that the combination of basalt, and steel fibers at 0.25, and 0.75 % respectively produced optimum results.
