When fibers like steel, glass, polypropylene, nylon, carbon, aramid, polyester, jute, etc are mixed with concrete known as fiber reinforced concrete. To overcome the deficiencies of concrete; fibers are added to improve the performance of concrete. In this research hybrid reinforced concrete is made by using steel and nylon 6 fibers. The inclusion of both steel and nylon 6 fibers are used in order to combine the benefits of both fibers; structural improvements provided by steel fibers and the resistance to plastic shrinkage improvements provided by nylon fibers. So the aim of this project is to investigate the mechanical properties (compressive strength, flexure strength and split tensile strength) of hybrid fiber reinforced concrete under compression, flexure & tension. The total volume of fiber was taken 0.75 % of the total volume of concrete. In this experimental work, four different concrete mix proportions were cast with fibers and one mix without fibers. Four different mix combinations of steel- nylon 6 fibres were 100-00%, 75-25%, 50-50% and 25-75%. Superplasticizer was used in all mixes to make concrete more workable. The results show that compressive, split tensile and flexural strength of hybrid fiber reinforced concrete increase by increasing the quantity of steel and nylon 6 fibers. The increase in compressive and tensile strength due to the incorporation of steel fiber is greater than that of using nylon fiber. For the nylon 6 fibers, adding more fibers into the concrete has a limited improvement on splitting tensile strength. Inclusion of nylon 6 fibers along with steel fibers results in considerable improvement in flexural strength as compared to solo steel fiber.
