浙江地区回弹法检测泵送混凝土强度曲线修订

Revision of the Strength Curve of Pumping Concrete by Rebound Method in Zhejiang Area

根据浙江省工程建设标准DB 33/T 1049-2008《回弹法检测泵送混凝土抗压强度技术规程》(以下简称"原规程")修订要求,针对浙江地区泵送混凝土特点,重新研制了回弹法检测碎石泵送混凝土的测强曲线,误差明显低于行业标准JGJ/T 23-2011《回弹法检测普通混凝土抗压强度技术规程》(以下简称"部规程")及原规程的要求,同时研究了回弹测强的各种影响因素及误差。

According to the revision request of Zhejiang engineering construction standard named DB 33/T 1049-2008 ＂Technical Specification for Inspection of pumped Concrete Compressive Strength by Rebound Method＂（hereinafter referred to as ＂original standard＂）,against the characteristic of the pumping concrete in Zhejiang Area,the strength testing curve for the pumping concrete by rebound method was developed renewedly,the error was lower significantly than those of the industrial standard named JGJ/T 23-2011 ＂Technical Specification for Inspection of Concrete Compressive Strength by Rebound Method＂（hereinafter referred to as the ＂ministerial standard＂） and the original standard. Meanwhile,various influence factors and error of testing the compressive strength by rebound method were studied.
