Abstract
Abstract Using iron waste to resemble concrete properties is the purpose of this study, that could be applied in rigid pavement and deck of bridges. The unique shape of spiral gives it this privilege; other researchers didn’t use this shape (used: powder, swarf, etc). Two groups of mortar were prepared, with and without SBR. Each of these groups of mortar was reinforced with spiral fibers of iron waste. The fiber waste was approximately (3 cm) in length and (1 cm) in diameter. The fibers were added at different percentages (6, 10, 12%) by weight of sand. These groups were allowed to cure for 28 days. The results show an enhancement of strength for each group after measuring the strengths of compressive and flexural. Moreover the properties (dry density and water absorption) were improved too. The lowest result of dry density and water absorption were (2132.2 Kg/m3, 9.09%) at 6% with and without SBR respectively. The best results of compressive and flexural strength were (36.88 MPa, 8.0893 MPa) at 12% without and with SBR respectively. It was concluded that the spiral fibers of iron waste can partially replace the fine aggregate with reinforcing and improving the properties of mortar.
