Abstract: In this project modified hybrid concrete- a novel construction material is manufactured with fibers (steel fibers, polypropylene fibers) and silica fume by drilling through the cement and mortar in order to develop a high strength concrete. The primary purpose is always to develop a cement with increased.physical and mechanical properties. Experiments to study the mechanical properties of the hybrid concrete were carried out. The present study aims at producing the concrete specimen by reinforcing constant level of fibers (steel fibers of 0.7%, and polypropylene fibers of 0.3%) with the different percentage (5%, 10%, 15% and 20%) of silica fume and then comparing it with normal and fiber reinforced concrete. Different tests were carried out on the hybrid concrete specimen like compressive strength test, flexural strength test, and durability tests on normal concrete. The result obtained from the above tests were supreme than the normal concrete, the hybrid concrete exhibits series of crevice while loading and also has higher flexural and compressive strength than the normal concrete.
