•An effective utilization of e-waste plastics and glasses in construction products is reviewed.•Potential use of e-plastic in cement and concrete composites are discussed.•Performance of cementitious composites with e-glass and e-fibre are reported.•The e-waste has great potential to use as construction material. The exponential development of the electronic industry and changes in people's lifestyle have increased the discarding rate of waste electronic appliances and electrical equipments rapidly. The disposal of electronic waste (e-waste) has become a serious challenge to developing and developed countries as toxic substances and heavy metals present in e-waste could harm human health and the atmosphere. From the perspective of environmental concerns, it is necessary to properly dispose or reuse e-waste in any forms to prevent pollution. In recent years, a growing number of studies are primarily associated with utilization of e-waste as construction materials. This paper provides a critical and comprehensive review of different types of e-waste which can be utilized as source material in the form of binder, fine/coarse aggregate, and fibre in the mortar, concrete, and precast products. More specifically, this review highlights the positive aspects, future research needs, and limitations of using e-waste in construction. Overall, it is suggested that e-waste offers huge potential benefits when it is utilized in construction products, thereby reduces e-waste management problems and saves the earth from environmental pollution.
