摘　　要：对高强橡胶混凝土进行了单轴受压试验,得到了含不同掺量、不同粒径的高强橡胶混凝土的应力-应变曲线。分析了橡胶掺量、胶粉粒径对高强橡胶混凝土的单轴抗压强度、极限应变、初始弹性模量和破坏形态的影响。研究结果表明:橡胶掺量对高强橡胶混凝土的单轴抗压强度、极限应变、初始弹性模量和破坏形态的影响都比较明显;胶粉粒径对高强橡胶混凝土的强度、初始弹性模量和破坏形态有一定的影响,对极限应变的影响不明显。Uniaxial compressive experiment for high strength crumb rubber concrete is conducted,and the stress-strain curve of high strength crumb rubber concrete with different contents and size of crumb rubber is obtained.The influence on uniaxial compressive strength,ultimate strength, elastic modulus and failure mode by different content and size of crumb rubber is analyzed.The test result show that the influence of rub- ber contents on tmiaxial compressive strength, ultimate strength, elastic modulus and failure mode is obvious.The influence of crumb rubber size on uniaxial compressive strength, elastic modulus and failure mode is existent,but the influence on ultimate strain is unobvious.
