摘要
利用超声检测方法对掺60目、1-3mm、3～6mm橡胶颗粒（粉）的橡胶混凝土进行超声声速及抗压强度测试。试验结果发现：橡胶混凝土超声声速与抗压强度之间存在幂函数关系，超声声速随抗压强度的提高而增大，超声声速与抗压强度随橡胶掺量的增大而减小，随粒径的增大而增大。
Ultrasonic speed detection is made on the rubber concrete with different rubber diameters of 0.25 mm, 1-3 mm, 3-6 mm and corresponding compression test is also carried out. By using ultrasonic test method and observing the experimental result can the author discover a power function relation between ultrasonic speed of rubber concrete and its compressive strength,that is, ultrasonic speed of rubber concrete will increase as the compressive strength increases,while the speed and strength will decrease with increased quantity of mixed rubber but increase with the increased particle sizes.
