实体混凝土抗压强度检测方法的探讨

Discussion on the methods of testing entity concrete compressive strength

本文分析了回弹法和钻芯法检测实体混凝土强度的利弊,提出了利用钻芯强度修正回弹强度的修正系数的计算,解决了回弹法测试精度低、钻芯法工作量大等缺点,既降低了对结构的破坏,又对混凝土抗压强度有较高精度的推定,具有较好的推广应用价值.

The advantages and disadvantages of resilience method and drilling core method in detection of compressive strength of entity concrete were analyzed in this paper.The calculation method of modified coefficient η was proposed by using drilling core strength to modify resilience strength,through which the disadvantages of low test accuracy in resilience method and workload in drilling core method were solved.It not only reduced the damage to the structure,but also had a higher accuracy in presumption of the compressive strength of concrete,and with good application value.
