摘要：

To overcome the problems of large error in strength measurement and low accuracy in prediction, this paper proposes a method to measure the compressive strength of nano modified concrete based on the grey entropy correlation method. First, collect the tensile strength value of concrete specimen, and eliminate the abnormal value of data through Grubbs test. Then, the subjective weight matrix is constructed, and the combined weight is obtained by weighted fusion method; Finally, the grey correlation degree between the strength data series is calculated, the compressive strength measurement function is constructed, and the correlation coefficient is used to modify the measurement function to obtain the strength measurement results. The results show that after 35 days, the compressive strength can reach 95.80 MPa, the accuracy can reach 98.5%, and the measurement error is only 0.03%, indicating that this method can improve the measurement effect of compressive strength.
