摘要
针对浙江地区泵送混凝土特点,研究了回弹测强的各种影响因素,研制了回弹法检测泵送混凝土的测强曲线,曲线相关系数达到0.941,误差明显低于建设部规程(JGJ/T23-2001)的要求。
According to the characteristic of the pumping concrete in Zhejiang province area,and taking the effects of the rebounding test strength method into account,we studied the special or region strength curve of the rebounding test strength method for the pumping concrete, Based on our result,we find the relativity modulus of the curve is 0.941 ,which is much lower than the standard of the ministry of the houses item JGJ/T 23-2001.
