Abstract

This study examined HDPE (high-density polyethylene) plastic waste as an added material for concrete mixtures. The selection of HDPE was based on its increased strength, hardness, and resistance to high temperatures compared with other plastics. It focused on how HDPE plastic can be used as an additive in concrete to increase its tensile strength and compressive strength. 156 specimens were used to identify the effect of adding different percentages and sizes of HDPE lamellar particles to lower, medium, and higher strength concrete for non-structural applications. HDPE 0.5 mm thick lamellar particles with sizes of 10 × 10 mm, 5 × 20 mm, and 2.5 × 40 mm were added at 2.5%, 5%, 10%, and 20% by weight of cement. The results showed that the medium concrete class (with compressive strength equal to 10 MPa) had the best response to the addition of HDPE. The 5% HDPE addition represented the optimal mix for all concrete types, while the 5 × 20 mm size was best.

Highlights

Plastic has long been considered a manmade material with many benefits
high-density polyethylene (HDPE) size additions low-quality concrete, medium-quality concrete, a lamellar particles quality concrete can for be non-structural explained asapplications follows. to determine the effect of HDPE
The previous study has discussed the development of lightweight concrete using HDPE additions (25%), opening up new development opportunities for nonstructural and structural applications [52], our findings show that the concrete with added plastics should be directed to medium concrete strength

Summary

Introduction

Plastic has long been considered a manmade material with many benefits. It has lightweight properties and is shaped to the designer’s desires. Research on beaches has shown that coastline plastic waste in 192 countries in 2010 amounted to between 4.8 and 12.7 million metric tons [6]. This waste threatens marine organisms [7] and has led to many demands to restrict plastic use and reshape behavior at the consumer level [8]. In 2018, processing plastic waste for energy used 43% of all of the collected post-consumer waste stream [1].
