Concrete is most popularly used construction material having several desirable properties like high compressive strength, stiffness and durability under usual environmental factors. Plain concrete has very low tensile strength, limited ductility and a low strain at fracture. It has been delivered that concrete reinforced with endurable amount of fibre acquires better performance in compression, flexural, toughness and energy absorption. Cubes of size 150mmX150mmX150mm to check the compressive strength and beams of size 500mmX100mmX100mm for checking flexural strength were casted and cylinders of size 100mm Diameter and 200mm depth to check the split tensile strength. All the specimens were cured for the period of 7, 14 and 28 days before crushing. Physical properties of various materials used in this project were carried out and result were tabulated.M30 grade concrete mix design was worked out and proportion were given based on the mix design and control concrete specimens were casted and 7,14 and 28 days strength was tabulated. In future, Steel fibres content were varied by (0.5%, 1.0%, and 1.5%, 2%). All the specimens were cured for the period of 7, 14 and 28 days before crushing and treated rubber various percentage of replacement on fine aggregate (2.5%,5%,7.5% ,10%) and its viability for replacement are discussed in this project.
