摘　　要：在钢筋混凝土结构服役寿命中,混凝土强度是联系结构安全性的重要指标。较为准确地检测混凝土质量,对于结构物而言是十分重要的。进行了英国女王大学研发的LIMPET混凝土强度监测设备对于中国混凝土的适用性验证。采用LIMPET拔出试验仪和液压式万能试验机对几种国内常用混凝土强度的试件进行测试,对数据进行统计分析之后,总结出国内常用混凝土的LIMPET拔出强度与轴心抗压强度之间的相关关系曲线,对现场评估结构物中混凝土强度提供相关依据,也为LIMPET仪器在中国的标准化提供试验支持。During the whole service life of reinforced concrete structures, the strength of concrete is an important index to structural safety.To detect the quality of concrete accuratelyis significantly important for the structures.It verified the applicability of LIMPET pull-off tester developed by Queen＇s University Belfast to Chinese concrete.On the basis of testing on several common concrete test cubes in China by LIMPET pull-off tester and hydraulic universal testing machine and statistical analysis on the data, it concluded the correlation curve between the LIMPET pull-off tensile strength and the cube compressive strength of these concretes, provided some evidence for evaluating the in-suit strength of concrete in the structure and provided experimental support for the standardization of LIMPET pull-off test in China.
