摘　　要：文章主要通过实验研究的方法,对再生轮胎橡胶混凝土的压缩强度、弯曲强度、轴心压缩强度、弹性模量及其徐变性能进行分析。实验结果表明,当橡胶颗粒掺量和再生粗骨料不断增加时,混凝土的压缩强度、弯曲强度、轴心压缩强度和弹性模量均处于不断下降趋势,徐变表现为增加趋势;当橡胶颗粒掺量大于10%之后,前四项力学性能下降速率加快;当橡胶掺量和环境相对湿度降低时,混凝土的徐变速率不断增加。This paper mainly analyzes the compressive strength,flexural strength,axial compressive strength,elastic modulus and creep properties of recycled tire rubber concrete through experimental research methods.The experimental results show that when the content of rubber particles and recycled coarse aggregates continue to increase,the compressive strength,flexural strength,axial compressive strength and elastic modulus of concrete are all in a downward trend,and creep shows an increasing trend;when the amount of rubber particles is greater than 10%,the first four mechanical properties decrease at a faster rate;when the amount of rubber and the relative humidity of the environment decrease,the creep rate of concrete increases continuously.
