混凝土回弹检测结果偏差研究

Study on deviation of concrete snapping back testing result

指出现行无损检测规程把碳化深度作为一个参量用来克服某些混凝土回弹法测强的影响因素,通过某一回弹法测强课题研究中偶尔发现的混凝土表面层中性化现象,揭示了回弹法检测中假碳化现象对混凝土检测强度评判的误区。

It indicates that present lossless testing regulations take carbonization depth as a parameter to overcome influent elements of some concrete snapping back method measures strongly, according to occasional discovering carbonization appearance in concrete surface layer during measures strongly task research of a snapping back method, it reveals the erroneous zone of false carbonization appearance to concrete testing intensity judge during snapping back method test.
