The increasing amount of Polyethylene Terephthalate (PET) plastic waste that is difficult to decompose naturally causes serious environmental problems. One alternative utilization is to use PET plastic waste mixed with sand as an artificial aggregate to replace coarse aggregate in concrete. PET plastic waste and sand are processed through heating and molding into 2 cm sized granules. Tests include Impact Test Value, Los Angeles Abrasion Test, specific gravity, water absorption, and aggregate volume weight. The test results show that the mixture of plastic waste (PET) with sand meets the eligibility requirements as a coarse aggregate based on the SNI and ASTM standards used. The average Impact Test value of 8.5%, Los Angeles abrasion 34.73%, bulk specific gravity 2.49, SSD 2.53, and water absorption 1.71% are declared to meet the standards.
