摘　　要：文中结合某房屋结构实体混凝土强度检测,提出回弹检测数据需要进行修正;通过推定区间上下限值法和龄期修正法,依据两本不同的规范进行处理,得出框架柱及框架梁混凝土回弹值均可取C13;再分析两种不同方法的准确性,得出推定区间上下限值法的结果具有较高的准确性及可操作性,而龄期修正法的结果不适用且存在诸多问题,为后续类似工程项目提供借鉴与参考。In this paper, combined with the concrete strength testing of a building structure, the rebound testing data need to be revised. By inferring the upper and lower limit value method of interval and the age revision method, and treating according to two different codes, it is concluded that the concrete rebound value of frame column and frame beam can be C13. After analyzing the accuracy of the two different methods, it is concluded that the results of the upper and lower limits of the inferential interval method have higher accuracy and Operability,while the results of the age revision method are not applicable and have many problems, provide reference and reference for the follow-up similar project.
