This project aims to study the mechanical properties of lightweight aggregate mix High Impact Polystyrene type electronic waste (HIPS), which, in a trial by all factors, including the cement-sand (S/C) = 0.2, 0.3, 0.4, by the weight of water cement ratio (W/C) = 0.55 and 0.45, 0.50, HIPS = 10, 15, 20 percent of the total weight of the samples tested from the tests, it was found that the ratio of total mass, light that is best suited to achieve the concrete mass, light that has the lowest density at 28 days: water-cement (W/C) = 0.55, sand cement (S/C) = 0.4 and HIPS = 20. The percentage is greater density kg/m3 and an equal ratio of 1630 the most appropriate to achieve concrete, light mass of the pressure at most 28 days: water-cement (W/C) = 0.45, sand cement (S/C) = 0.2 and HIPS = 10. The percentage values are getting pressure equal to the test piece from the MPa 28.43 all jobs can be organized. In light of the type of concrete structure There is a unit of weight equal to 1756.67 kg/m, and there is resistance pressure equal to 28.43 percent compared to receipts and MPa are increasing of a bird street, mortar. Choose from the best proportions found in part 1 is that 7 days = 27.56 MPa till 28 days = 28.07 strengths increased 1.85% MPa only. If there are no ingredients that remove waste HIPS come in comparison with a mixture containing waste HIPS in the curing period of 28 days, the ingredients with the highest strengths without waste HIPS are a mixture of 1 MPa and with waste = 37.88 HIPS is part 1 = 28.43 MPa, which is different, just 25%.
