INFLUENCE OF E-WASTE AND SILICA FUME ON THE STRENGTH CHARACTERISTICS OF M30 CONCRETE
The electronic industry is the world's largest and most rapidly growing manufacturing industry. Because e-waste has a negative impact on human health, it must be repurposed in some way to be environmentally benign. Huge loads of electronic gadgets are sent across seas consistently, yet after their utilization, they make a muddled waste matter including an assortment of unsafe weighty metals, acids, toxic mixtures, and non-biodegradable polymers. E-waste is collected, dismantled, separated, and exported for recycling by a number of commercial companies. The compressive and tensile strengths of concrete specimens constructed from E-waste material will be tested in this study. The e-waste material is used to make coarse aggregates of 20mm in size. For a concrete mix of M30, multiple concrete mixes are made by replacing regular coarse aggregate with ewaste material in various percentages such as 0 percent, 20%, 40%, 60%, 80%, and 100%. Cement is replaced with Silica fume in percentages of 0% to 10% when coarse aggregate is replaced. The impact of replacing coarse aggregate with e-waste material and cement with Silica fume on concrete parameters such as compressive and tensile strength for hardened concrete at 28 and 90 days will be investigated. For each concrete mix, a certain number of examples are made.
