1·In this paper, the physical properties and chemical composition of limestone from Cejing of Shahe are investigated and the activity of calcined lime are tested according to production condition.

研究了沙河市册井石灰石的物理性能、化学成分，参照邢钢的生产条件进行煅烧实验，并对石灰进行活性度测试。

2·If industry wastes lime, calcined gypsum and sulfate are grinded with the high-calcium fly ash, activity increases, soundness improves, and activity index can meets the demand for S95slag.

采用工业废石灰、煅烧磷及无机盐激发剂，加上短时粉磨处理以激发高钙灰，可显著改善其安定性，活性指标可达到S95矿渣粉水平。

3·The phosphogypsum can be calcined into quality building plaster via neutralized with lime, ball milled or water washed, ball milling pretreated.

磷石膏经石灰中和、球磨或水洗、球磨预处理，可煅烧成优等品建筑石膏。

4·The palletizing process with slaked lime, cement clinker and calcined plaster as additive was also introduced.
