A compendious review on the influence of e-waste aggregates on the properties of concrete

The idea of managing and recycling electronic waste is getting broad acceptance because it is a resource that is rapidly available in bulk, contains various hazardous substances and has a low recycling rate. Meanwhile, increasing industrialization and urbanization has increased concrete production and consumption, resulting in environmental problems via resource depletion. As a result, the utilization of aggregates prepared from e-waste is a viable solution to different con-servation and environmental issues caused by e-waste and concrete production. This article discusses the types of e-waste and types and production techniques of e-waste aggregates (e-waste plastic and cathode ray tube (CRT) glass). The primary focus of this article is the influence of e -waste aggregates on the properties of concrete, including workability, fresh and dry density, compressive strength, flexural strength, splitting tensile strength, and thermal resistance. More-over, this study also discusses the suitable percentages of e-waste aggregates that can be incor-porated as natural coarse aggregates to prepare sustainable concrete for structural and nonstructural purposes. It can be concluded that e-waste modified concrete provide a glimmer of hope for the safe and sound disposal of increasing quantity of e-waste. However, more compre-hensive experimental studies are required to explore full potential of e-waste aggregates as nat-ural coarse aggregates replacement for the large-scale production of concrete.
