Green Concrete: Incorporation of E-wastes. A Green Concept

      Аннотация: On one hand, a mushrooming boost in the world population, urbanizations and gargantuan housings plus infrastructural developments have altogether twisted the arm of researchers, scientists, and engineers to invent alternative innovative, affordable, eco-benevolent, and essentially sustainable building materials. On the other hand, piles of modern wastes generated by discarded electronic and electrical equipments found to impact pessimistically on environment; surface and sub-surface water; soils; besides leaching of highly toxic elements escorting to human health hazards. Incorporation of these profuse recycled E-wastes with concrete not only turns it to “Green concrete” but also offers a systematic solution to manage its landfills through its consumption for good cause of presenting green construction material sans compromising its sustainability, strength and durability. It is a concept to “Go Green, Live Green”, i.e., mitigation of emission of primary green house gas CO2 to provide a relief for gigantic dilemma of global warming; conservation of energy and natural restricted resources; reduction of pollution of air, water, soils; and of course, with a cost-effective approach!
