混凝土无损检测可以在不影响结构或构件受力性能或其他使用功能的前提下,直接在结构或构件上对混凝土进行质量检测。由于是在结构或构件上直接测试,成型条件、养护条件、受力状态等都大致相同,从这方面来讲,比使用标准试件来做测试对象,可靠性大大提高。但由于一些客观或人为的因素,使得无损检测的可靠性有时也受人质疑。那么目前常用的无损检测方法都有哪些弊端?在实际的检测工作中如何提高无损检测的可靠性?本期特别策划请专家及检测专员对混凝土无损检测可靠性方面问题进行探讨。
Concrete non-destructive testing can be carried out directly on the structure or component of the concrete quality inspection without affecting the performance of the structure or component or other use of the premise. Because it is tested directly on the structure or component, the forming conditions, curing conditions, stress state and so on are roughly the same, and in this respect, the reliability is greatly improved compared with the use of standard test pieces. However, due to some objective or artificial factors, the reliability of non-destructive testing is sometimes questioned. So what are the disadvantages of the commonly used nondestructive testing methods? How to improve the reliability of nondestructive testing in the actual testing? This special planning experts and commissioners to explore the reliability of nondestructive testing of concrete.
