试验通过控制球磨时间得到不同颗粒级配的试样，研究不同颗粒级配对试样物理性能的影响。研究结果表明：细颗粒越多标准稠度用水量越多，凝结时间越慢；细小颗粒影响试样水化速率，细颗粒越多能加速试样的水化，提高水化速率；颗粒级配不同对试样2h强度影响不大，1d强度随细颗粒所占比例的增加而减小。

In the experiment, different particle size distribution of the sample is made by controlling the milling time, the paper studies the effect of different particle size distribution on the sample’s physical performance. The re?sult shows: the more fine particles, the more standard consistency water, the slower setting time; Fine particles af?fects the sample’s hydration rate, more fine particles accelerates the hydration of the sample, and increases the hy?dration rate;Different particle size distribution has little effect on the sample’s 2h strength, 1d intensity decreases with the increase in the proportion of fine particles.
