用回弹法推定“标号混凝土强度”的方法

Determination of Mark Concrete Strengh by Rebound Method

针对现行《回弹法检测混凝土抗压强度技术规程》(JGJ/T23—2001)中的混凝土强度推定方法,对设计标号和强度等级验收水平及其关系进行分析,建议用回弹法推定混凝土强度时应考虑被测构件的设计标准和施工控制标准,以尽量符合原设计、施工水平,做出客观的评价。

According to the determination method of concrete strength in ＂Technical Specification for Inspection of Concrete Compressive Strength by Rebound Method（JGJ1T 23--2001）＂, this paper analyses the level and relations between design mark and strength calss. The design standard and control standard should be considered in strength inspection by rebound method so as to make objective evaluation.
