摘要
提出了局部高阻尼水泥砂浆构件的概念,并通过对50个不同配比、不同部位配置聚合物的砂浆试件的阻尼测试,比较了各种因素对阻尼比的影响效果。试验表明,聚灰比以及测试时试件的应力状态对阻尼比都有显著影响,乳液的添加可以显著提高砂浆的阻尼性能。
In this paper,the concept of local high damping cement mortar component is presented.The experiment on the damping properties of 50 local high damping cement mortar specimens with different mix rate of Styrene-acrylic emulsion are carried out.The influences of several parameters on the damping ratio of cement mortar components are analyzed.The experimental results shows that the polymer-cement ratio(P/C) and the stress situation of component have an important influence on damping properties and Styrene-acrylic emulsion can enhance the damping behaviors of the cement mortar.
