Currently in this industry facing many challenges due to lack of support from government for the recycling and reuse of waste tyre by products, but manually a large quantity of high strength steel fibers (21 13 Mpa) are being extracted from waste tyres, the dominant use of this tyre-derived steel is a scrap steel to manufacture new iron or steel. This research Work is focused on the use of steel fibers extracted from waste tyres and mixed in Concrete with different proportions to produce a concrete more strong than ordinary concrete. Different concrete specimens were casted and tested in universal testing machine to find flexural strength. The cement were replaced with steel fibers 0.5% 1%, 1 .5%, 2% and 2.5%. Result shows that the Concrete with inclusion of 1.5 % Waste Tyre Steel Fibers of 0.5 inch length gave maximum flexural strength (i.e. 0.675 MPa) which is 26.6% more than that of plain concrete. Concrete with inclusion of 1.5% WTSF of 1 inch length gave maximum flexural strength (i.e. 0.69 MPa) was observed which is 28.3% more than that of plain concrete Generally, it can be concluded that Waste Tyre Steel Fibers concrete with inclusion of 1.5% of WTSF of 1 inch length is optimum in terms of flexural strength and workability.
