混合骨料混凝土的动弹性模量试验研究

摘要

Though the experiment, the dynamic modulus of elasticity of specified density concrete are studied. From the result of experiments, the influence of different replacement ratio of lightweight aggregate, age of concrete to the modulus of elasticity are analysed.%通过试验,对混合骨料混凝土的动弹性模量进行了试验,分析研究了骨料替代率、水灰比以及龄期等对混凝土动弹性模量的影响,以及动弹性模量与静弹性模量之间的关系.
