The primary objective of this study is to assess the viability of integrating recycled plastic components sourced from electronic waste (E-waste) into diverse construction applications, offering a sustainable response to the growing challenges posed by the escalating E-waste crisis. This meticulous research examined key strength parameters in M20 grade concrete mixes, including compressive, split tensile, and flexural strength, varying the proportion of waste E-plastic in coarse aggregate. It aimed to reveal E-plastic’s impact on concrete’s mechanical properties for informed construction decisions. Durability was also assessed, covering water absorption, resistance to chloride attacks, and sorptivity. Non-destructive tests like ultrasonic pulse velocity tests were used for a holistic understanding of concrete behavior. This study contributes significantly to sustainable construction materials by offering insights into how waste E-plastic affects concrete’s long-term performance and resilience in diverse environments. The investigation concentrated on a thorough examination of the mechanical, durability and micro attributes of concrete specimens featuring varying proportions of waste E-plastic content, spanning from 4% to 28%. Additionally, the research was modified by replacing a portion of the cement with fly ash, amounting to 10% of the total weight, with the intent of augmenting the overall characteristics and performance of the E-plastic-infused concrete.
