冶金工业部建筑研究院在国庆节前夕试制成功我国第一台混凝土超声波探伤议。这台探伤仪的操作情况经多方面严格鉴定证明,完全达到了现在的国际水平。超声波探伤仪是无损构件测定混凝土质量的最好方法之一。它是根据声波在构件中的传播速度和其发射能量的削减程度来确定混凝土的动弹性模量及蜂窝和裂缝的位置。采用这种方法,可以在实际结构中迅速、简易、 Metallurgical Industry Building Research Institute in the National Day eve trial successful China’s first concrete ultrasonic testing. The operation of this flaw detector by many aspects of strict identification, fully reached the current international level. Ultrasonic flaw detector is a non-destructive component of the best way to determine the quality of concrete. It is based on the acoustic propagation velocity in the member and its emission energy reduction to determine the dynamic modulus of concrete and honeycomb and crack location. This method can be used in the actual structure quickly, easily,
