不同测强曲线对混凝土抗压强度的影响及分析

Influence and Analysis of Different Testing Strength Curves on Concrete Compressive Strength

结合实际工程项目中检测得出的混凝土回弹数据,采用 JGJ/T 23-2011《回弹法检测混凝土抗压强度技术规程》中的测强曲线和云南省地方标准 DBJ 53/T-52-2013《回弹法检测混凝土抗压强度技术规程》中的测强曲线分别对其进行计算并分析,对云南地区混凝土抗压强度计算推定值时测强曲线的选择具有重要意义。

Combined with the rebound data of concrete detected in the actual project,use JGJ/T23-2011"Technical Specification for Inspecting of Concrete Compressive Strength by Rebound Method"and the strength measurement curve in the local standard JGJ/T23-2011"Technical Specification for Inspecting of Concrete Compressive Strength by Rebound Method"of Yunnan Province to calculate and analyze the rebound data.It is important for the selection of strength curve in the calculation of compressive strength of concrete in Yunnan area.
