Elastic modulus is an important mechanical parameter of concrete. Static stressed elastic modulus test is made, so as to study the factors influencing the elastic modulus of C50 concrete. Conclusions drawn are as follows: water binder ratio is the main factor that influences the compressive strength of concrete; the type of coarse aggregate is the main factor that influences the elastic modulus of concrete; the elastic modulus of concrete that is prepared by granite aggregates is low; the elastic modulus of C50 concrete can be improved when some basalt aggregates are mixed.

摘要/Abstract

摘要： 为了探究影响C50泵送混凝土弹性模量的若干因素，采用5因素3水平的正交试验方案，按照《普通混凝土力学性能试验方法标准》进行了静力受压弹性模量试验研究，结果表明影响混凝土抗压强度的主要因素是水胶比，影响混凝土弹性模量的主要因素是粗骨料的品种。花岗岩配制的混凝土弹性模量相对较低，但在花岗岩中混掺入玄武岩可有效改善C50混凝土的弹性模量。
