对已建成的钢筋混凝土结构物或正在施工的混凝土质量进行鉴定,给以定性、定量的评价,是非破损试验方法所要解决的问题。 非破损测试方法的种类很多,超声法及“超声-回弹”综合法是其中广泛使用的方法之一。目前国外应用非破损方法检验混凝土已成为保证混凝土质量的必不可少的测试手段。在国内近几年来有关科研单位对混凝土非破损测试方法进行了大量试验研究工作,解决了一批混凝土工程质量评定任务, The evaluation of the quality of the completed reinforced concrete structure or the concrete under construction and the qualitative and quantitative evaluation are the problems to be solved by the non-destructive test method. There are many types of non-destructive testing methods. Ultrasound and “ultrasonic-rebound” synthesis are among the widely used methods. At present, the application of non-destructive methods to test concrete in foreign countries has become an indispensable test method for ensuring the quality of concrete. In recent years, a number of experimental studies on concrete non-destructive testing methods have been carried out by relevant research institutes in the country and a number of concrete engineering quality assessment tasks have been resolved.
