Abstract
E-waste, including devices like phones and computers, poses serious environmental risks. To mitigate these, the construction industry is exploring e-waste as a material to enhance concrete strength and durability. Hence, the present study assesses the performance of M40-grade high-strength concrete by replacing coarse aggregates with 0% to 30% e-waste plastics at various intervals. As the e-waste replacement increased, fresh concrete’s workability decreased gradually. The mix containing 30% e-waste experienced the largest reduction in slump value, showing a 10% reduction compared to the control mix. Compressive strength at 28 days declined with increased e-waste content, with the most desirable results observed in mixes containing up to 15% e-waste, which is the recommended substitution level for satisfactory strength. Flexural and tensile strength tests revealed similar trends, with a decline beyond 10-15% e-waste substitution. Throughout the research, a 15% e-waste substitution consistently yielded positive outcomes across all concrete grades, enhancing workability, strength, and resistance to acid attack while controlling water absorption.
Keywords: E-waste, Concrete, Flexural strength, tensile strength, Compressive Strength.
