摘　　要：简要介绍了拉脱法检测混凝土抗压强度技术的原理、特点和已完成的试验和验证工作过程,采用夹紧、拉脱、数据采集为一体的拉脱仪,利用自动调节径向夹紧力的特点,完成对芯样试件的拉脱试验。拉脱法检测混凝土抗压强度技术被列为2013年度住房和城乡建设部规范编制计划。This paper describes the principle and characteristics of inspection of concrete compressive strength by pull-off test, and the process of testing and validation are also introduced. The technology uses clamping, pull-off, gathering data as one of the pull-off device, and the automatic adjustment of the radial clamping force is used to pull-off the core samples. Inspection of concrete compressive strength by pull-off test was listed as 2013 annual specification preparation of the plan of the Ministry of Housing and Urban-rural Development.
