Utilization of Plastic Waste as a Substitutional Material for Paving Block Manufacturing

Besides reducing environmental pollution, the use of garbage or plastic waste can also be used as an alternative to building materials. The potential for utilizing plastic waste still needs to be developed, by conducting research on plastic waste to be substituted into paving block making materials, by replacing some of the sand material in normal paving blocks. The research used is an experimental method. In this test the test object was made by adding additives/mixture of plastic waste as a filler/mixture in the paving block mix with a percentage of plastic mixture of 2.56%, 5.26%, 8.11%, 10.11%. Then the paving block is tested for compressive strength at the age of 28 days which is possible to have reached the maximum compressive strength value. The results of the paving block compressive strength test will increase according to the increase in the percentage of plastic mixture. The compressive strength of paving blocks with a plastic mixture of 0%, 2.56%, 5.26%, 8.11% and 10.11% obtained compressive strengths of 10.44 MPa, 10.64 MPa, 10.95 respectively MPa, 11.15 MPa and 11.33 MPa. The increase in compressive strength of normal paving blocks (0% mixture of plastic waste) was 1.83%, 4.6%, 6.35% and 7.86%. The highest compressive strength occurs in paving blocks with a mixture percentage of 10.11% plastic waste, according to the SNI-03-0691-1996 standard the compressive strength is included in the quality level D which can be used for parks and other uses.
