混凝土强度检测方法主要采用超声回弹综合法和单一回弹法,要根据不同条件下选择最适宜的方法。两种检测方法在原理上不同,随着混凝土使用时间变久其强度换算值的变化趋势也不同。文章也从混凝土的内部结构和外部的养护条件上进行分析,对比出了两种检测方法的差异性。通过单一回弹法与超声回弹综合法检测混凝土强度的对比分析,给实际的工程检测做出一些参考。
Concrete strength testing methods mainly use the ultrasonic rebound method and a single rebound method, according to different conditions, select the most appropriate method. The two detection methods are different in principle. As the concrete working time becomes longer, the change tendency of the converted value of the intensity is also different. The article also analyzes the internal structure of concrete and external curing conditions, and contrasts the differences between the two detection methods. Through a single rebound method and ultrasonic rebound combined method to test the strength of concrete contrast analysis to the actual engineering test to make some reference.
