E-waste is from the electrical and electronic devices such as computers, laptops, phones and television and home appliances. It can be used for reuse, resale, salvage, recycling or disposal. It becomes a very hazardous thing in our daily life. So to reduce this effect we made a project on concrete with E waste. This may reduce the effect of E waste and its dangerous gases.
Our project deals with the usage of E waste along with the chemical admixtures in concrete. The hazardous substances in E waste are PCB (polychlorinated biphenyls), CFC (chlorofluro carbons), PVC (polyvinyl chlorine), Arsenic, barium, etc…When these E wastes are used in the concrete mix it will not emit their gases.
We replaced the E waste for coarse aggregate. Initially E wastes were broken into small pieces. The mix design was done by M40 grade of concrete by IS method. Ordinary Portland cement of 43 grades was used. The broken pieces of E-waste were replaced by 0%, 10%, 20%, 25%, 30% to the coarse aggregate along with the chemical admixture. Compressive strength and Tensile strength were tested and compared with control concrete. Experiments done shows the increase in strength when E waste is used in concrete. Thus the usage of E waste also decreases the cost of construction.
