Abstract:

The accumulation of electronic waste (E-waste) has become a significant global environmental issue, driven by the characteristics of the modern era and the ever-increasing use of electronic devices. Thus, a sustainable approach is necessary to overcome this issue. In this paper, an overview of utilizing E-waste as a sustainable aggregate in concrete production was comprehensively reviewed. The basic composition, characteristics, and production techniques were discussed. In addition to that, the colour, shape, size, aggregate crushing value, and water absorption of E-waste concrete were also discussed. Furthermore, the workability properties such as slump flow, mechanical properties (compressive strength, flexural strength, tensile strength) and thermal resistance of E-waste concrete identified by the various researchers were summarised. Based on the literature review, it is concluded that the shape and size distributions of E-waste particles greatly influenced the aggregate properties, and the percentage of replacement of E-waste aggregate affect the workability and mechanical and thermal properties of E-waste concrete.
