混凝土阻尼比研究

Study on the Damping Ratio of Concrete

摘要:

配制了普通混凝土、轻骨料混凝土、粉煤灰混凝土、橡胶粉混凝土、聚合物混凝土和聚合物粉煤灰混凝土等6类共计33个配合比的混凝土，采用自由振动法测试了各类混凝土的阻尼比，得到了一批混凝土阻尼比的基础性数据．在着重提高混凝土阻尼比的同时．还兼顾了混凝土抗压强度和弹性模量等力学性能的改善．

Abstract:

Six classes of concrete were tested, namely, ordinary concrete, lightweight aggregate concrete, fly ash concrete, rubber powder concrete, polymer concrete and polymer fly ash concrete. The total mix was 33. Free vibration method was employed to measure the damping ratio of the concretes. A great deal of fundamental data for the damping ratio of concrete was obtained. While emphasis were mainly put on raising the damping ratio of concrete, as well as the compressive strength and elastic modulus of concrete.
