Utilization of Plastic Waste Polyethylene Terephthalate (Pet) as a Coarse Aggregate Alternative in Paving Block

PET plastic waste is found everywhere in Banjarbaru City compared to other plastic wastes. It is an excellent prospect to reuse the PET plastic waste. The demand of mountain rock and stone from natural resources increases as happened in Aranio Sub District, Banjar Regency. This research is expected to find one way of suppressing the growth of the number of stone mines or natural stone. Based on SNI 03-0691-1996, the classification of the paving block differentiated according to its usage class, one of which is the C quality used by pedestrians. PET waste used as a coarse aggregate previously processed into aggregate with the ratio of cement material, fine aggregate, a coarse aggregate of 1:6:4. PET waste is processed by melting PET and forming into aggregates. The paving with PET waste process by a hydraulic press machine and tested for strength after 28 days. The result of weight measurement with the specimen increases the amount of PET in the paving block mixture, the paving weight decreases as well as the compressive strength.
