The Portland cement has showed a negative impacts to the environmental and therefore researchers from all over the world are interested in using wastes and their recovered extraction processes to discover fresh construction materials. The present review manuscript is an attempt to reconsider the use of abandoned computer / electronic wastes, also known as E-waste, which is used as alternative materials for the development of a variety of non-toxic concrete for the industrial and construction sectors. The main goal of this review is to provide current position of concrete materials for this reason, it is necessary for understanding these modern, complicated, valuable, but hazardous wastes. These materials are used as alternate for crude aggregate in building material production. The brand-new, cutting-edge, and ground-breaking concept are used for the production of environmentally friendly, cost-effective green concretes. Furthermore, chemical, physical, and metallurgical reuse procedures for E-waste, as well as its benefits and dis-advantage with heat, tensile, the endurance characteristics for Electronic-wastes such as green concretes, unsafe compound, are appraised. This research also examines the application glass as E-waste from cathode rays are used in concrete, mortar, and cement paste. The E-waste materials are used as bituminous mixture. The "Urban Mining" strategies have recognized the application of non-biodegradable materials recovered as E-waste plastics as a partial substitute for natural courses or fine components. This review paper assists to promote the implementation of green precast E-waste in the construction sector in a sustainable and cost-effective manner, it also impasse the exhaustion of natural resources, environmental contamination in earth and underground water. It also concern over the environmental pollution and to defend the health of living organisms.

The present state of nanotechnology in concrete is summarised in this study. The terms "nanotechnology," "nanoscience," and "nanoengineering" all have concrete definitions. Instrumentation and computational materials science advancements, as well as their practical applications, are reviewed in this article. nanoengineering and nanocomposites alteration of cement-based material was focus of this research, which examines current developments in this field.
