Utilization of Waste Low Density Polyethylene for Cement Brick
Keywords:Plastic concrete pavement blocks, Low-density polyethylene waste, Water cement ratio, Compressive strength.
One of the most pressing challenges throughout the world is the correct disposal of plastic garbage. Using such garbage can help to alleviate both prior and current issues. The major goal of this study was to see if utilizing leftover low-density polyethylene as a partial replacement for sand in cement bricks was practical and feasible. We employed cement, fine aggregates, coarse aggregates, ground plastic, and water in this experiment. The proportions were 2: 1.7: 4 in the mix (cement, sand, stone). The ground plastic was employed at a rate of 0%, 20%, and 50% by volume sand. Furthermore, sand has a density of 1,650.0 kg m3 and crushed plastic has a density of 710. 4 kilograms per square meter. It was discovered that when the plastic concrete strength grew, the compressive strength dropped. At 5%, 10%, and 20% plastic content, the compressive strength ranged from 16.21 N/mm2 to 37.05 N/mm2, respectively. Although there was a considerable drop in density as the plastic component increased, the density was reduced by roughly 5% when plastic replaced 20% of the total fine aggregate.
