针对混凝土表面涂层干膜厚度难以进行无损检测的问题,采用超声波涂层测厚仪对不同强度等级的混凝土涂层干膜厚度进行了测量,并对测量结果进行了不确定度评定及合格检验.结果表明:不确定度评定能够有效地反映测量结果的可信程度,也是判别测量结果是否满足要求的主要依据;混凝土强度等级越高,混凝土涂层干膜厚度测量结果的不确定度越小,反之亦然.
In view of the difficulty of nondestructive testing on the dry film thickness of concrete surface coating, the thickness of dry film of concrete coating with different strength grades was measured by ultrasonic coating thickness gauge, and the measurement results were evaluated and qualified The results show that the evaluation of uncertainty can effectively reflect the credibility of the measurement results and also the main basis for judging whether the measurement results meet the requirements. The higher the concrete strength level, the less the uncertainty of the measurement results of the dry film thickness of concrete coating ,vice versa.
