Studies on Concrete containing E plastic waste
Author(s)- Lakshmi.R, Nagan.S
Utilization of waste materials and by-products is a partial solution to environmental and ecological problems. Use of these materials not only helps in getting them utilized in cement, concrete and other construction materials, it helps in reducing the cost of cement and concrete manufacturing, but also has numerous indirect benefits such as reduction in land-fill cost, saving in energy, and protecting the environment from possible pollution effects. Electronic waste, abbreviated as e-waste, consists of discarded old computers, TVs, refrigerators, radios – basically any electrical or electronic appliance that has reached its end-of-life. Efforts have been made in the concrete industry to use non biodegradable components of E waste as a partial replacement of the coarse or fine aggregates. An experimental study is made on the utilization of E-waste particles as coarse aggregates in concrete with a percentage replacement ranging from 0 % to 30% on the strength criteria of M20 Concrete. Compressive strength, Tensile strength and Flexural strength of Concrete with and without E-waste as aggregates was observed which exhibits a good strength gain. Ultrasonic tests on strength properties were executed and the feasibility of utilizing E plastic particles as partial replacement of coarse aggregate has been presented.
