    The global electronic waste (e-waste) crisis has ignited environmental concerns, driven by the nonbiodegradable and toxic nature of e-waste plastics. Investigating the incorporation of nano-iron oxide particles (NIOPs) and sisal fibers as reinforcements for e-waste plastic coarse aggregate (EPWCA) concrete reveals potential improvements in the concrete's physical and mechanical properties. However, there is still uncertainty surrounding the long-term durability and resilience of EPWCA concrete reinforced with NIOP and sisal fibers when exposed to harsh environmental conditions. This study investigates the integration of NIOP and sisal fibers into EPWCA concrete, focusing on acid, chloride, and freeze-thaw resistance. The findings demonstrate that NIOP significantly bolsters acid resistance, freeze-thaw durability, and chloride ion migration, due to its filler effect and densification of the microstructure. However, sisal fibers have an adverse effect on the environmental resilience of EPWCA-based concrete due to their hygroscopic nature.The results from freeze-thaw and chloride tests have verified the enhanced durability offered by EPWCA.However, natural coarse aggregates outperformed EPWCA when it comes to acid resistance. This study contributes valuable insights into sustainable construction practices to mitigate the e-waste crisis and improve the long-term performance of EPWCA-based concrete.
