Abstract This study presents a comprehensive and novel investigation into the environmental sustainability mechanical behavior of concrete incorporating three classifications waste tyre rubber—powder, crumb, chips—as partial replacements for natural aggregates. In contrast to prior research that typically focuses on single rubber type or limited replacement ranges, this work systematically evaluates influence various forms across full spectrum inclusion levels, ranging from 0% 30% in 5% increments. Concrete mixtures were prepared with two distinct water-to-cement (w/c) ratios (0.4 0.5) examine interaction between mix design parameters content. Mechanical properties such as compressive strength, ultrasonic pulse velocity (UPV), dynamic modulus elasticity assessed after both 28 90 days curing. Notably, containing at 0.4 w/c ratio (0.4WR5) achieved peak strength 58.81 MPa days, while 8% exhibited highest UPV 5660 m/s challenging conventional perception addition invariably degrades performance. These findings demonstrate optimized rubberized mixes, particularly 5–10% can deliver high enhanced durability characteristics, contributing sustainable construction without compromising structural integrity. Furthermore, highlights critical curing time rubber-modified concrete, offering valuable guidance engineering applications. By effectively utilizing rubber, contributes circular economy principles reduction concrete’s footprint, presenting practical route diverting landfills.
