影响回弹法检测混凝土强度准确性的因素

Factors that Influencing Accuracy of Concrete Strength with Rebound Method Detection

回弹法因其仪器简单、操作方便、经济、迅速,对混凝土结构无破损和具有一定的测试精度,而始终保持着它在混凝土检测领域内的优势地位。回弹法在使用过程中还是出现了较多的仪器率定准确性、人员操作、测试面处理、外界环境、碳化深度检测等处理不当问题,造成了较大的测试误差。从上述几个方面提出了提高回弹法的检测准确性应综合考虑的因素。

The rebound method still maintains its advantageous position in the field of concrete testing due to its simple apparatus,easy operation,quickness and economy,no harm to concrete structures and a certain degree in testing accuracy.But during its application regarding apparatus calibration accuracy,the operation,the treatment of testing surface,the external environment and the carbonation depth detection etc.,many misconducts will still occur which would result in relatively big testing errors.Based on the above facts,the author put forward some comprehensive factors in order to improve the testing accuracy with rebound method.
