| 摘 要： | 材料的阻尼是衡量材料本身减振性能的主要指标.采用自由振动法测试得到了一批橡胶混凝土小变形阻尼比的基础性数据.试验结果表明:所采用的阻尼比测试方法和试验过程是可靠的;对同类型的混凝土,混凝土的阻尼比随橡胶掺量的增加而增大;混凝土的弹性模量随橡胶掺量的增加而降低;橡胶胶掺量在4.5左右时,可获得阻尼比、弹性模量和抗压强度均较高的混凝土.

| Abstract: | Damping ratio is the main index representing the property of materials in reducing vibration.Free vibration method is employed to measure the damping ratio. A great deal of fundamental data for the damping ratio of rubber powder concrete in small deformation is obtained. The analyses of experimental results conclude that:the testing method and procedure for damping ratio are reliable;for concrete in the same class,the damping ratio increase with increasing rebber powder;Young's modulus decrease with increasing rebber powder benzene;with the rebber powder ratio falls in around 4.5%,the damping ratio and Young's modulus and compressive strength are both high. |
