Abstract: The use of recycled aggregates in concrete opens wide range of opportunities in the reuse of materials in the building industry. The use of recycled aggregates is a good remedial to the problem of an excess of waste material. . In fact, none of the results revealed the unsuitability of the recycled aggregates in concrete. This Work focuses on the possibility of the use of recycled aggregate concrete as a structural material with replacement level of 25%, 50% and 75% by weight of normal aggregates along with the hook end steel fiber used in this study varied from 0.5% .1.0%, and 1.5 % by Volume of concrete. Bagasse ash is also used as a partial replacement of Portland cement with 5, 10 & 15 % by weight of binder in order to improve the properties of RAC. The use of bagasse ash replace cement in RA concrete could improve compressive strength to be higher than that of concrete without bagasse ash at the same W/B ratio. This Work focuses on the possibility of the use of recycled aggregate concrete with bagasse ash and steel fibers as a structural material. The properties of concrete evaluated include compressive strength, Split tensile strength, flexural strength
