摘要

With the regression analysis of SPSS software, the diameter and the ratio of height to diameter were included into the control variables, and the prediction model of the correction coefficient between the non-standard specimen and the standard specimen was established when the C25 pumping concrete was used to test the strength of concrete by drilling core method.
