Mechanical Properties of Concrete Contain Waste Fibers of Plastic Straps

Abstract This study examined the utilization of polyethylene terephthalate (PET) strap waste as fibers to reinforce the concrete. The fibers were obtained by simply cutting the strap. An investigation was carried out on 7 batches containing PET waste fibers as a volumetric fraction of concrete. The parameters were the fibers fraction ratio ranging from (0-0.5) % and aspect ratio (2.5 and 3). Compressive strength, slump test, and splitting tensile strength were the test supplied to concrete. The test results indicate that the PET fibers improve the splitting tensile strength and slightly decrease the compressive strength and workability. So that, the concrete produced can be used in paving, industrial flooring, precast concrete, and shotcrete. Furthermore, a way to reuse plastic waste will be utilized to contribute to saving the environment.
