This study addressed the issue of recycling waste plastic bottles as recycled fiber (RPF) into sustainable fiber-reinforced concrete (WPFRC). Thus, effects different RPF lengths (30, 50, and 70 mm), widths (2, 4, 6 contents (0.3, 0.45, 0.6 vol%) on performance WPFRC were systematically evaluated through laboratory test series workability, fresh unit weight, compressive flexural strengths, drying shrinkage, water absorption, ultrasonic pulse velocity. Results indicated that addition had a negligible effect properties mixtures, while significantly enhancing load-bearing capacity reducing shrinkage in specimens, particularly at early ages. Additionally, all specimens exhibited low absorption rates high velocities, indicating good quality durability. Overall, found an content 0.45% by volume, length mm, width 2 mm yielded best for WPFRC. As result, incorporating fosters development strong, durable, materials green construction.
