Experimental Study on Mechanical Strength and Durability of E-waste Mixed Concrete

The construction industry is facing a shortage of natural resources, leading to the exploration of alternative building materials. The study investigated the durability, effectiveness, and performance of high-strength concrete using crushed e-waste. The results of the experiments demonstrated that the optimal composite structure, exhibiting maximum compressive strength (33.65 MPa) and flexural strength (6.9 MPa), could be achieved by incorporating 8% e-waste. Furthermore, the highest split tensile strength (4.66 MPa) was obtained with a 12% e-waste mixture. The durability of concrete was tested in various chemical environments. It was found that 20% e-waste mixed concrete experienced lower compressive strength loss when exposed to sodium sulphate, and minimal strength loss when exposed to sulfuric curing. E-waste is being used to address the shortage of raw materials and contribute to sustainable waste management practices in the construction industry.
