Effects of HDPE Plastic Waste Aggregate on the Properties of Concrete

Abstract

Abstract: Polymer waste volumes have surged in recent years as a result of growing industrialization and fast improvements in living standards. In Malaysia, the majority of polymer waste is discarded rather than recycled. This circumstance results in major issues such as waste of natural resources and pollution of the environment. Polymer products, such as synthetic fibres, plastics, and rubber, are petrochemical compounds that disintegrate slowly in nature. Even after a long amount of time, plastic materials are not easily biodegradable. In reality, a wide range of waste materials can be used as a cement matrix inert. For the manufacture of the polymer concrete, trash bag plastics were employed as polymer wastes HDPE in this study (PC). The purpose of this research is to investigate the characteristics and characterisation of polymer HDPE as a coarse aggregate replacement in concrete. Temperatures of 160°C, 170°C, 180°C, 190°C, and 200°C were used in the heating procedure. By volumetric approach, five compositions of coarse aggregate with varied crushed stone: HDPE waste ratios of 0:100, 15:85, 30:70, 45:55, and 60:40 were utilised. The use of polymerwaste as coarse aggregate in traditional concrete was examined. With fresh and hardened concrete tests, the effects of polymer wastes on the workability and strength of the concrete were investigated. After 28 days, the compressive strength of the PCwas determined to be suitable for nonstructural use. The findings of the cost research revealed that the PC is more cost effective than traditional concrete. Keywords: Polymer Wastes HDPE; Coarse Aggregate; Compressive Strength; Properties
