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,
