摘　　要：本文针对橡胶集料混凝土若干力学性能进行了试验研究,结果表明橡胶集料混凝土的强度随着橡胶集料掺量的增加呈下降趋势且强度发展较普通混凝土缓慢,橡胶集料混凝土的弹性模量仅为普通混凝土的38%至88%,峰值轴压应变为普通混凝土的1.2至1.5倍,相应的能量吸收超过普通混凝土10%至30%。试验同时发现橡胶集料混凝土试件破坏前均经历了相当大的变形,表现出很好的延性特征。并根据橡胶集料混凝土的自身材性特点介绍了其在工程方面的应用和展望。Certain mechanical performance of Crumb Rubber Concrete is researched experimentally in the article. The results show that with the increasing composition of CRC, the strength of CRC decreases and develop more slowly than that of Plain Concrete, and the elastic modular of CRC is only 38% to 88% percentage of that of Plain Concrete. The maximum axial compression strain is the 1.2 to 1.5 times than that of Plain Concrete, and corresponding absorption of energy exceeds the Plain Concrete by 10% to 30%. Simultaneously, through the experiment, the elements of CRC undergo largely deformation, showing better ductility. According to its own characteristic of CRC, the application and prospect in the field of engineering are explored.
