摘要
摘 要：为了缓解建筑垃圾对生态环境的不利影响，提高建筑垃圾的资源化利用率，使用再生骨料部分替代天然骨料制备了再生混凝土。通过对比分析再生混凝土中天然骨料和再生骨料的界面性能，并研究了骨料的掺配比例对再生混凝土抗压强度、劈裂强度以及变形性能的影响，在尽可能提高再生骨料利用率的基础上，确定了再生混凝土中再生骨料的最优掺配比例。
Abstract: In order to alleviate the adverse effects of construction waste on the ecological environment and improve the resource utilization rate of construction waste, recycled concrete was prepared by using recycled aggregate instead of natural aggregate. The interfacial properties of natural aggregate and recycled aggregate of recycled concrete was compared, and the effect of the aggregate blending ratio on compressive strength, splitting strength and deformation performance of recycled concrete is studred. On the basis of increasing the utilization ratio of recycled aggregate as much as possible, the optimum blending ratio of the recycled aggregate of concrete was determined.
