回弹法检测对某渠首混凝土抗压强度的检测

Detection of Compressive Strength of Concrete in a Canal Head by Rebound Method

在混凝土强度无损检测中,回弹法这种检测方法应用比较广泛,当出现没有根据规定制作试件或者是标准养护试件数量不够时,并且怀疑构件混凝土强度时,可通过回弹法根据相应的技术规程来进行检测。需要注意的是,混凝土内外质量基本一致是采取回弹法的前提。如果混凝土内部和表层之间存在明显质量差异,比如,当受到火灾、腐蚀以及内部有缺陷时,对于混凝土的强度不能通过回弹法直接进行检测。

In the nondestructive testing of concrete strength,the rebound method is widely used.When there are no specimens made according to the regulations or the number of standard curing specimens is insufficient,and the concrete strength of the component is suspected,the rebound method can be used to test according to the corresponding technical regulations.It should be noted that basically consistent of internal and external quality of concrete is the premise of adopting rebound method.If there are obvious quality differences between the inside and the surface of concrete,for example,when subjected to fire,corrosion and internal defects,the strength of concrete cannot be directly tested by rebound method.
