Abstract
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 conservation 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. Moreover, this study also discusses the suitable percentages of e-waste aggregates that can be incorporated 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 comprehensive experimental studies are required to explore full potential of e-waste aggregates as natural coarse aggregates replacement for the large-scale production of concrete.
