Experimental Investigation on Partial Replacement of Coarse Aggregates by Flyash Aggregate in Concrete

Abstract

The rate of E-waste generation is increasing day by day in the modern world. 80 to 85% of different electronic items wastes disposed of in landfills or incinerators which can include or discharge certain lethal gases into air, may influence environment and human health conditions. The extraordinary measure of lead in e-waste alone causes harm in the vision, blood and kidneys of person. Just 12.5% of e-waste is right now reused. Most ideal approach to dispose e-waste is to use it as partial replacement for coarse aggregate in concrete which is eco-friendly measure. It helps to eliminate the concrete materials deficiency problem which is currently going on in construction industry and it also reduces the cost of concrete. Concrete mixes with different percentages of E-waste were casted. It has been decided to make three different types of conventional specimens with partial replacement of E-waste on a percentage of 10%, 20%, and 30% to coarse aggregate in M25 grade of concrete with water cement ratio of 0.45. Conventional specimens are also prepared for same grade of concrete. The mechanical properties of the concrete specimens were compared and studied.
