Abstract: “We studied the effects of using industrial steel solid wastes resulted from lathes to enhance the compressive strength of concrete. In average, 3-4 Kg/lathe of steel waste fibers are produced on daily basis. Such steel waste can be recycled in order to mitigate its environmental hazards. Moreover, using it to reinforce concrete is a feasible and sustainable solution. Six (6) concrete cube specimens were casted with (1% and 2%, in terms of concrete weight) and without steel waste then tested under compression. Also, the workability of the casted fresh concrete with different ratios of steel waste (0%, 1%, and 2%) was estimated utilizing the slump test. The results shows that adding lathes steel waste fibers to plain concrete enhances its compressive strength while the workability of the fresh concrete containing the steel waste fibers decreases.”
