摘要
利用废旧轮胎生产橡胶颗粒,并制备橡胶混凝土,是废旧轮胎再生利用的重要途径之一;同时,橡胶混凝土往往会遭受风、地震和车辆等动力作用。主要阐述了橡胶掺量、粒径和其表面处理等因素对橡胶混凝土动态抗压强度、抗冲击、抗疲劳和阻尼特性等动力性能的影响及机理,并提出了有待进一步研究的问题。已有文献表明,尽管添加橡胶一定程度降低了混凝土的动态抗压强度,但可以显著改善混凝土的抗冲击、抗疲劳和阻尼特性。
Using waste tires to produce rubber particles and prepare rubber concrete is one of the important ways to recycle waste tires,and rubber concrete tends to be subjected to wind loads,earthquakes,vehicle loads and other dynamic actions.The influence of rubber content,particle size and surface treatment on the dynamic compressive strength,impact resistance,fatigue resistance and damping property of rubber concrete is reviewed,and some problems are proposed for further investigation.It has been shown in the literatures that although the rubber particles reduce the dynamic compressive strength of rubber concrete to a certain extent,it can significantly improve the impact resistance,fatigue resistance and damping property of rubber concrete.
