Evaluation and Analysis of M20 Grade Concrete Blended With Nonperforming Battery Cells As a Replacement of Coarse Aggregate

E-wastes are emerging as a tremendous source of various health hazards as well as environmental problems. With the up rise in number of consumers in the global digital market scenario and the flurry of modern electrical products, the e-waste being generated has been growing leaps and bounds. Battery is an e-waste, with production of several tons per year. Batteries are mostly sent to landfill with high management cost. Further due to poor infrastructure for disposal, the various types of batteries which contain very toxic metals in it are dumped over landfill which pollutes the soil, ground water as well as surface water sources. The study intended to look out for a path to use these spent battery cells in the concrete as a coarse aggregate so that the burden of the management of the gigantic amount of e-wastes can be relieved a bit. In the following study, the focus was upon the consumption of the spent e-waste AA battery cells used in households for the purpose of making M20 grade of concrete by replacing the natural coarse aggregate by 5% and 10% of it. The results revealed that as we increase the amount of replacement of the spent battery cells, there is a decrease in the strength of the concrete. But the decrease is small for up to the range of 10% of the replacement. The parameters tested were the compressive strength and the split tensile strength of the M20 grade of concrete. The test also concluded that the self-weight of the concrete decreases with respect to the control mix as the percentage replacement increases.
