Abstract: This experimental research study investigates the results of some fresh and mechanical properties of self-compacted concrete which the sand has been partially substitute with different percentage by volume with crushed fine polyethylene waste. A total of nine SCC mixtures including constant of water/binder ratios, cement content and SP percent with partial replacement of sand with polyethylene waste by (0, 5, 10, 15, 20, 25, 30, 35 and 40%) were designed. Fresh and mechanical properties of SCC that involve time and diameter of slump flow, "V" funnel time, flow time and height ratio of L-box in addition compressive, flexural, tensile strength tests and ultrasonic pulse velocity were measured at 28th day curing ages. The all results were compared and explained the reasons for their differences with the control mix. Tests results showed that it is possible to produce the light weigh SCC by using correct and suitable percent of polyethylene waste substitution with fine aggregate. In addition, their workability improved and ductility increased while the mechanical properties remain within the allowable limits.
