从工程检测实例探讨结构实体混凝土强度检测中钻芯法修正回弹检测结果的一些误区

摘要

当对回弹法检测混凝土强度的结果有疑问时，常用钻芯法进行修正，因此长期以来对钻芯法和回弹法之间的关系存在一些认识上的误区，如认为钻芯法一定比回弹法准确，或者有了钻芯法修正可以不必认真对待回弹法检测，以及在有钻芯法修正的情况下可以对表面损伤的混凝土采用回弹法进行检测等。本文基于工程实例，从理论上分析了这些观点的错误所在，并提出相应的建议，以真正达到钻芯法和回弹法优势互补提高检测精度的目的。%When there is doubt about the result of concrete strength tested by rebound method , core drilling method is often used for correc-tion.So there are some misunderstandings between rebound method and core drilling method , which are like these:core drilling method is more accurate than rebound method , or rebound testing may be curtly operated under core drilling correction , and the strength of surface damaged concrete can be tested by rebound method under core drilling correction .Based on actual testing examples , this paper theoretical-ly analyzed these wrong viewpoints , and put forward some advices to achieve the goal of complementing the advantages each other of re -bound method and core drilling method , and so the testing accuracy would be improved .
