Experimental Investigation on E-Waste Concrete with Silicafume

Abstract

Electronic waste, commonly referred to as "E-waste," is any electronic device that is no longer useful or has reached the end of its useful life. This can include computers, smartphones, tablets, televisions, refrigerators, and other household appliances, as well as industrial equipment and medical devices. Many electronic devices contain hazardous materials such as lead, mercury, cadmium, and brominated flame retardants, which can be harmful to human health and the environment if not disposed of properly. Improper disposal of e-waste can lead to environmental pollution, as well as health problems for those who are exposed to the hazardous materials and is passing severe toxic waste issues to the human beings and the environment. E-waste is a growing problem worldwide, as electronic devices become more common and quickly become obsolete due to advances in technology. Recycling and proper disposal of e-waste is becoming increasingly important as more electronic devices. From then literature review it is inferred that the E waste was added to the concrete by partial replacement of Fine Aggregates. Recommended dosage of E waste as partial replacement of coarse aggregate was 10 % concrete. Minimum studies were carried out as a partial replacement of fine aggregates. To recommend the optimum percentage of E waste as replacement of fine aggregate. No effective method to prevent the leaching of toxic components from E waste concrete. The Compressive Strength, Split-Tensile strength, Rebound Number, UPV test and Durability tests was carried. Therefore, by incorporation of Silica Fume the mechanical properties such as Compressive strength and Tensile strength are improved. The increase in the % of E- waste decreases the density and hence E-waste concrete can be adopted for light weight construction. The quality of E-waste concrete improved by the incorporation of Silica Fume. which is evident from the rebound hammer and Ultrasonic Pulse velocity results. And also Durability Test results. The Optimum % of E-waste was found to be 5%. Overall, the combination of E-waste and Undensified Silica Fume develop a sustainable concrete which can prevent the unnecessary dumping of E-waste and act as a light weight concrete.
