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.

The technological performance and social acceptance of water treatment in electromagnetic waves were investigate in this paper that studied in samarra university laboratories to detection the effect of electromagnetic field on water properties, it is worth to mentioning that magnetic field treatment does not leave any traces of waves in the treated water. Electromagnetic treatment applicate on water samples using the electromagnetic field with 1.5 tesla intensity and for two continuous hours by a tube with ¾ inch. diameter and 1m length. The chemical and physical properties were studied before and after treatment. It was observed that there was a slight increase in some properties and a decrease in other properties. The reason was either to increase the dissolved oxygen and to dissolve the suspended particles and total hardness. As well as, significant decrease in total count of bacteria
