摘要：
Effect of 5 kinds of grinding aids on grinding performance of Alite-rich Portland cement was studied by determining specific surface area, sieve residue, particle size distribution and particle size parameters. The impact of grinding aids on cement hydration process was studied by resistivity, hydration heat, XRD and SEM. The results show that all grinding aids have good grinding effect, especially for large particle at late period. Grinding aids enhances the hydration degree of Alite-rich Portland cement leading to the increase of cement strength.
