Enhancing Sustainability in Concrete Construction: Utilizing LDPE and HDPE Plastics as Fine Aggregate Replacements

Abstract
In this study, a potential replacement for conventional aggregates in the creation of concrete is being investigated. The building industry, which is in increasing demand, is faced with sustainability and waste disposal problems that might be resolved by using plastic waste in concrete. The study looks at a number of factors that determine concrete's properties, such as physical, mechanical, and the environmental impact of using plastic waste as a substitute material. This study takes a look at prior studies on the topic, highlighting the benefits and downsides of using HDPE and LDPE in concrete and providing an overall overview of where the field stands at the moment. The findings suggest that using plastic waste concrete as a building material can reduce the environmental effect of construction materials while being both affordable and sustainable,

摘要
本研究旨在探究可替代混凝土传统集料的潜在材料。需求日益增长的建筑业面临可持续性与废弃物处置双重难题，而在混凝土中掺入塑料废弃物或可破解上述困境。本研究考察了影响混凝土性能的多项关键因素，包括以塑料废弃物作为替代材料时所涉及的物理特性、力学性能及其环境影响。本研究梳理了该领域的既往研究成果，重点分析了高密度聚乙烯（HDPE）与低密度聚乙烯（LDPE）掺入混凝土后的利弊，并对当前该领域的研究现状进行了全面综述。研究结果表明，将塑料废弃物制备为混凝土建筑材料，既可降低建筑材料的环境负荷，又兼具经济性与可持续性。
