摘　　要：在回弹法检测混凝土抗压强度的过程中,当结构混凝土强度推定值低于其砼设计强度等级的标准值时,需要在此构件回弹最低测区混凝土强度换算值测区内进行取芯。本文着重介绍了芯样加工、试验中应注意的事项,对回弹法和钻芯法两种检测结果进行对比,对构件强度推定值偏低产生的原因进行了系统的阐述分析。In the process of testing concrete compressive strength by rebound method,when the estimated value of the strength of the structural concrete is lower than the standard value of the strength grade of the concrete design,it is necessary for this coring rebound in the lowest test area for concrete strength conversion area.This paper mainly introduces the matters needing attention in core sample processing and test,the two test results of rebound method and core drilled method are compared,the reasons for the low presumption of component strength are systematically analyzed.
