现场测试混凝土弹性模量的方法研究

Field Testing Method for Elastic Modulus of Concrete

近年来,混凝土的弹性模量值引起了日益广泛的重视,其在计算钢筋混凝土的变形、裂缝扩展、温度应力以及估算预应力损失等方面是必不可少的指标。采用传统的静力载荷试验的方法测试混凝土材料的弹性模量存在着费事、费时、代表性不强和难以全面检测等缺点,我们利用现场无损检测的方法测试混凝土结构和材料的弹性模量,较好地解决了上述问题。

In recent years,the elastic modulus of concrete,which is an essential indicator for calculating the deformation of reinforced concrete,crack propagation,temperature stress and estimating loss of pre-stress,etc.,is paid great attention.Traditional method of static load with the shortcoming of time-consuming and cumbersome,poor representation,difficult to fully detect,the method reported in this paper,a non-destructive testing method of field testing of concrete structures and the elastic modulus,provides a good solution.
