In this paper, the investigation regarding the effect of reinforcing steel fiber as well as polypropylene fibers over the normal high-performance concrete is done. The effect is examined over the slump, compressive strength as well as flexural strength. The combination of M40 (OPC 53 Vasavadatta) along with steel fiber and polypropylene fiber separately is used for study. Workability of fiber mixed concrete is tested at the time interval of initial stage, 60 min, 120 min and 180 min. Total 36 Cubes of size (150*150*150 mm) and 9 beams of size (700*150*150 mm) are casted to inspect. Cubes are tested at the age of 3 days, 7 days and 28 days. Flexural strength is determined on the 28th day. Based on experimental studies, the paper identifies the fibers combination indicates maximum compressive strength and flexural strength of concrete. Specimens were tested over the different age levels for mechanical properties of concrete. A detailed study was carried out of curing conditions over the compressive strength. The behavior of flexural load-deformation, compressive strength of conventional concrete is briefly compared with fiber reinforced cementitious composites. Eventually the result derives that the addition of fibers to concrete resulted in increase in compressive strength as well as flexural strength compared to mixture of plain concrete.
