摘要

材料的阻尼是衡量材料本身成振性能的主要指标。本文采用自由振动法测试得到了一批羧基丁苯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

混凝土的阻尼比随丁苯胶掺量的增加而增大

混凝土的弹性模量随丁苯胶掺量的增加而降低;丁苯胶掺量在10％～15％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 set of fundamental data are obtained for the damping ratio of polymer concrete with carboxyl butyl benzene at small deformation. The analyses of experimental results indicate that: the testing procedure for obctaining damping ratio are reliable; for concrete in the same class

the damping ratio increases with increasing carboxyl butyl benzene; Young’s modulus decreases with increasing carboxyl butyl benzene; with the carboxyl butyl benzene ratio between 10% and 15%

the damping ratio

Young’s modulus and compressive strength can get a good combination.
