摘　　要：混凝土强度检测方法中,钻芯法因直观、可靠度及准确度高而被广泛应用。但芯样端面平整度、垂直度及端面处理方式等因素均会对芯样的抗压强度产生影响。本文主要研究C30等级混凝土试块钻取的芯样及结合某实际工程案例钻取的混凝土芯样采用磨平机磨平、水泥净浆补平、硫磺胶泥补平三种不同芯样端面加工方式对其抗压强度结果的影响。In the testing methods of concrete strength,the core drilling method is widely used due to its intuitiveness,high reliability,and accuracy.However,many factors can affect the compressive strength of the core sample,such as the flatness,verticality,and treatment method of the end face of the core sample.This article mainly studies the impact of three different processing methods on the compressive strength results of core samples drilled from concrete specimens with a concrete mix ratio grade of C30,including grinding with a grinding machine,cement slurry leveling,and sulphur mastic mortar leveling,combined with a practical engineering case.
