混凝土抗压强度回弹法在建筑结构检测与鉴定工作中的应用

Application of Concrete Compressive Strength Rebound Method in Building Structure Detection and Appraisal

混凝土强度回弹法检测与其快速、方便、直观、经济等诸多优势,已成为中国混凝土工程现场检测鉴定应用最为广泛的检测方法,结合多年从事建设工程检测鉴定实践,从影响回弹法检测结果的仪器选择、检测操作、检测构件及位置选择、混凝土浇筑龄期、表面碳化等方面进行分析,并论述回弹强度与试块强度的不同,以提高混凝土抗压强度回弹法在建筑结构检测鉴定中的精度,可为规范再次修订提供参考。

Concrete strength rebound method has become the most widely used detection method for on-site detection and identification of concrete engineering in China with its advantages of rapidity,convenience,intuition and economy.Combined with the author’s many years of practice in construction engineering detection and identification,starts from the selection of instruments,detection operation,detection components and location,concrete pouring age,the surface carbonization,and discusses the difference between the rebound strength and the test block strength,so as to improve the accuracy of the concrete compressive strength rebound method in the detection and identification of building structures,which can provide a reference for the revision of the code.
