Abstract :

This study explores the potential of using electronic waste (e-waste) as an alternative to traditional coarse aggregates (CA) in concrete production to address the growing concerns of e-waste accumulation and the depletion of natural resources in the construction industry. The research evaluates the sustainability, durability, and structural performance of concrete mixtures with e-waste replacing a portion of CA in M25 and M30 grade concrete. The workability, consistency, and mechanical properties, including compressive strength, split tensile strength (STS), and overall robustness, were tested for various e-waste substitution levels. The results indicate that optimized e-waste replacement levels can maintain or even enhance structural integrity, offering both resource conservation and sustainable waste management benefits. However, a 100% replacement led to a significant reduction in compressive strength, from 36.2 MPa to 15.56 MPa for M25 and from 42.47 MPa to 15.9 MPa for M30, showing a decline in structural performance. Future research will focus on microstructural analysis, long-term durability, and real-world applications to assess the industrial feasibility of e-waste-based concrete.
