Abstract: Road Infrastructure is an important driving force to achieve rapid and sustained economic growth in the changing technological innovation. A decent road system has an essential bearing on the monetary development of the nation. It is the obligation of roadway designer to keep concrete roads in activity commendable state by keeping pace with the fast extension and fortifying of the road arrangement yet they are experiencing issues to keep the roads in great condition. Consequently road development in our nation will be a ceaseless procedure, with concrete road reinforcing to be a real action for a long time to come. When rigid pavements are built, the mix design of concrete is focused around the compressive quality, which is utilized to guarantee that the target flexural quality as visualized in outline is attained to by and by, however exorbitant in beginning speculation, is modest in long run in light of low upkeep costs. This paper deals with experimental investigation on mechanical properties of M40 grade concrete by incorporating hooked end steel fibres in dosages of 2%, 2.5% and 3.0% by weight of cement into the mix. A comparative analysis has been carried out for conventional concrete to that of the hooked end steel fibre reinforced in relation to compressive and flexural strengths.

Keywords: Hooked end steel fibre, Concrete Mix Design, Compressive Strength, Flexural Strength.
