An experimental investigation on the strength of concrete by partial replacement of aggregate using E-waste

Abstract

E-waste is one of the fastest growing sector with the growth of 3–4% yearly, its was estimated to raise upto 55 million tons by 2025. Nowadays, inappropriate disposal of e-waste creates many environmental pollution in both developed and developing countries. Many researches have started to use the waste materials in the production of concrete including e-waste components. Now the recycling of e-waste creates the tremendous issues can cause several health hazards. The main objective of the study is to estimate the usage of printed circuit board to replace the conventional coarse aggregate at 12% for M25 grade concrete. In this paper, PCB of e-waste is used for the purpose of replacement of coarse aggregate. The maximal compressive strength was gained at 12% by partial replacement of e-waste plastic. The tensile and flexural strength also gains the maximal strength at 12%. It’s observed that the PCB of the E-waste concrete by using of with and without plasticizer reached its maximum strength at 12% replacement of coarse aggregate.
