Experimental Investigation on Performance of a Steel Fiber Reinforced Concrete on M25 Grade Concrete

Concrete is the most versatile construction material that can be used in fabricating of structures. Concrete is available in various types depending upon the necessity of structure. The key parameters that influence any structure are its strength and durability. In order to attain higher strength with normal concrete, there is a need of using some additional materials along with the main components in concrete i.e. Cement, fine aggregate, coarse aggregate and water. These additional materials function as reinforcement to concrete to increase the strength. In this research steel fiber is used in M25 concrete to target the strength. Steel fibers are one of the metallic fibers which possess high tensile property. Therefore influence of steel fiber on structural properties of M25 concrete is studied. In this regard various proportions of steel fiber i.e. 0%, 2%, 4%, 6%, and 8% by weight of binder are added to concrete. Each proportion of fiber is added to concrete and six specimens of cubes, cylinders and prisms are casted and cured for 7 days and 28 days. These specimens are tested for compressive strength, split tensile strength and flexural strength after specified curing period and the results of the tested specimens are noted and discussed for further analysis.
