Abstract: Despite growing interest in sustainable materials, the combined use of E-waste fibers and ceramic waste (CW) in high-strength concrete remains underexplored. Prior studies largely focus on single waste constituents in normal-strength concrete, providing limited insight into synergistic effects. This study addresses this gap by evaluating the fresh and mechanical performance of sustainable high-strength concrete incorporating both materials. This study investigates the effects of E-waste fibers (0.5–2.0% by cement weight) and CW as partial fine aggregate replacement (15–60%). Fresh and mechanical properties were evaluated using a MOORA-based multi-criteria approach. E-waste fibers improved compressive, flexural, and shear strengths up to 1.0%, while higher dosages reduced performance due to workability loss and fiber agglomeration. Optimal stiffness and load-carrying capacity were achieved with 15–30% CW replacement, demonstrating the potential of CW–E-waste fiber composites for sustainable high-strength concrete.
