Abstract: This project work represents the mechanical strength properties such as compression, splitting tensile and flexural strength of fiber reinforced concrete with addition of hybrid fibers. Steel and carbon fibers are added in fiber reinforced concrete at varying percentages of 3 % and 2 % at different ratios of (50:50) and (75:25) based upon the orientation. Carbon fibers are mixed all along with cement, aggregates, water and super plasticizers while mixing in the mixer machine because of its size whereas steel fibers are being sandwiched between the layers of concrete based on the orientation so that the fibers would be perpendicular to the point of application of load. The strength properties of fibers were tested by compression, splitting tensile, flexural and two point loading at 7, 14, and28 days. M40 grade of concrete is used as per IS1026: 2009. Workability of concrete is maintained by using super plasticizer. The test results are being noted in tables and compared with conventional concrete. From the obtained results it can be concluded that the strength of concrete is optimum when hybrid fibers steel and carbon are added at 3% (75:25) ratio.
