Abstract
E-waste management is the major threat around the globe, with increasing modernization, tremendous growth of technology and mainly due to upgradation of electrical and electronic goods. Disposal and recycling of these waste are becoming more harmful and deadly without proper procedures. On the other hand our natural resources are being depleted at enormous amount. So they are completely or partially replaced according to the needs. Cement is partially replaced by various other agents and Fine aggregate is replaced by M-sand. Eventually coarse aggregate should need a replacement, various materials are used as partial replacement of coarse aggregate, in this study coarse aggregate is partially replaced by e-plastic waste at specific percentages and strength of concrete is tested accordingly. On the strength criteria of M35 grade e-waste is partially replaced by 0%, 4%, 8%,12%,16%, of coarse aggregate, water cement ratio is kept as 0.45 for all proportions. Printed circuit boards are used as partial replacement for coarse aggregate. OPC 53 grade cement is used. The mechanical properties compression, split tensile and flexural strength are determined for 7days, 14days and 28days.
