Abstract In this study, the characteristics of ground granite powder with different times (0, 20, 40, and 60 min) were studied. The effects of grinding time and amount of granite powder (0%, 5%, 10%, 15%, and 20%) on the drying shrinkage of mortar were investigated. Scanning electron microscope and TG-DSC were used to analyze the microstructure and hydration products of granite stone powder mortar. Finally, gray entropy analysis was used to observe the key particle parameters affecting drying shrinkage; this was done by determining the gray entropy correlation between the particle parameters of granite powder and the 28 d drying shrinkage activity index of mortar. The results indicate that the highest proportion of the particle sizes in the range of 56.4—63.2 μm in the raw granite powder is 5.1%. After crushing, the proportions of the particle sizes in the ranges of 17.8—20.0, 22.4—25.2, and 15.9—17.8 μm are 3.5%, 3.3%, and 3.4%, respectively. With increasing grinding time, the drying shrinkage resistance first decrease, then increase and then decrease. Compared with the drying shrinkage rate of the reference mix, those of 5%-, 10%-, and 15%-stone-powder-added mortar mixes (ground for 40 min) at 28 d are lower by 11.9%, 35.2%, and 45.3%, respectively. Drying shrinkage decreased by 1.9% when the content increase to 20%. Gray entropy analysis shows that the particle size corresponding to the cumulative distribution of the particle size of the stone powder reaches 10%. Specific surface area and the particle content of 20~40 μm are found to be the key parameters affecting the drying shrinkage performance of mortar. The area average particle size and the scope of particles >60 μm had significantly minor effects on the drying shrinkage performance of mortar.
