Abstract Based on partial test data of ground cement, the prediction accuracy of 28d compressive strength of cement is compared between the single-variable one-time regression equation obtained by the method in appendix a of JC/T 738 and the multiple-variable one-time regression equation obtained by the data analysis function of Excel. The comparison results show that the prediction value of 28d compressive strength of cement is more accurate by using the multiple regression equation derived from Excel data.
