One of the ways to improve the strength properties of construction and demolition (C&D) wastes is to adopt the accelerated carbonation technique. The main objective of this study was to evaluate the effects of the eco-friendly carbonation approach on the mechanical properties of C&D aggregates together with crumb rubber. Crumb rubber with particle sizes ranging from 400 to 600 μm was added to the 20 mm recycled concrete aggregate (RCA) and crushed rock (CR) at 0.5, 1, and 2% by weight percentage of the aggregates. Then, the unconfined compression strength (UCS) and resilient modulus (M_r) tests were conducted on the carbonated RCA and CR samples together with crumb rubber, and the results were compared with those of the uncarbonated specimens. The results showed that the carbonation process led to a significant increase in the UCS values. However, carbonation resulted in a decrease in the deformability of the specimens compared with the uncarbonated specimens. Moreover, carbonation resulted in a significant increase in the M_r values compared with those of the uncarbonated values. Also, the carbonation process had a more substantial effect on the M_r values of the CR than of the RCA.

改善拆建废料强度特性的方法之一是采用加速碳化技术。这项研究的主要目的是评估生态友好的碳化方法对C＆D骨料和碎胶的力学性能的影响。将颗粒尺寸为400至600μm的粒状橡胶添加到20毫米的再生混凝土骨料（RCA）和碎石（CR）中，其含量为骨料的0.5％，1％和2％。然后，无侧限抗压强度（UCS）和弹性模量（M _r）对碳化RCA和CR样品以及碎橡胶进行了测试，并将结果与​​未碳化样品进行了比较。结果表明，碳化过程导致UCS值显着增加。然而，与未碳化的样品相比，碳化导致样品的可变形性降低。此外，碳化导致在M一个显著增加_{- [R}值与那些不含二氧化碳的值的比较。另外，碳酸化过程对所述M个较大幅度的效果_{- [R}比RCA的CR的值。
