The results show: (1) with high calcium mixing, concrete workability was modified, the water quantity needed for standardconsistence decreased, initial and final setting time increased;
结果表明：（1）高钙灰的掺入改善了胶砂的工作性，降低了标准稠度用水量，延缓了胶材的初终凝时间；
2
The powder produced by the method mentioned had narrow particle distribution and good consistence, which did not need further classification and could reach export product standard.
用该工艺方法加工亚微米碳化硅粉体，不需再次分级、粉体分布窄、一致性好，性能达到国外同类产品水平。
3
Taking the consistence as the X-axis, the peak area as the Y-axis, draw the standard curve.
