Production and Properties of Plastic Boxes Waste Concrete

Abstract

Waste residues from plastic crates used to transport fruit pose a serious environmental threat. In this paper, we investigated the use of this kind of waste in the production of green concrete. This study showed the effect of plastic boxes waste (PBW) on concrete properties. PBW was used as aggregate instead of fine aggregate (sand). Six mixtures containing varying amounts of PBW particles (5%, 10%, 15%, 20%, 25%, and 30%) were preparedin addition to a control mixture. The effects of PBW on concrete properties were evaluated using compressive strength, flexural strength, splittingtensile strength, density, water absorption, and ultrasonic pulse velocity (UPV). The use of plastic trash cans has a negative impact on the strength of concrete. Although the addition of plastic waste aggregates reduces the mechanical properties of concrete, using such wastes reduces the environmental impact of plastic waste and preserves natural aggregates for the future. Environmentally friendly concrete can be manufactured. However, a significant decrease in density was observed. Ultrasonic velocities were declined, indicating that this type of concrete is suitable for structural insulation. In addition, the study showed relationships between concrete properties. In this study, an upper limit for PBW content was proposed. The inclusion of this type of aggregate is a potential solution to the plastic waste problem and may improve concrete properties
