Evaluate the Feasibility for Making of Non-load Bearing Blocks Using Plastic Waste as Partial Replacement for Fine Aggregate
Solid waste disposal can contribute to the problem of environmental degradation. Most of the waste material is plastic-based because nature is not susceptible to plastic degradation. Numerous studies have been conducted to overcome the issue of the reuse of plastic waste in various fields such as civil engineering and construction. In this study, rejected polythene packaging covers from the manufacturing industry were used for partially replacing the sand in cement-sand non-load bearing block production. The high-density polyethylene (HDPE) and low-density polyethylene (LDPE) raw plastic waste used in this study were obtained from a packaging factory “Cleanpoly Packaging Pvt. Ltd, Kegalle,” and they were obtained in the fine particle size form from the “GREEN EARTH Waste Management Technologies Pvt Ltd, Negombo.” About 1:6 cement-sand mix design and 0.45 water-cement ratio were maintained with partial replacement of recycled plastic waste instead of sand in the percentages 15%, 20%, 25%, 30%, and 35%, respectively, for the sandcrete block production. All specimens were included for testing and for determining the compressive strength, split tensile strength, and water absorption at the 7th and 28th days. The density of the specimens was also measured. The findings show that specimens with 15% recycled plastic waste partial replacement at 28 days of age curing show the highest compressive strength and highest tensile strength which are 3.39 N/mm2 and 0.38 N/mm2 compared to the controlled specimen 2.8 N/mm2 and 0.28 N/mm2, respectively.
