中文摘要：

通过测定不同龄期水化率以及一定龄期的强度，对加入盐类和碱性激发剂不同产地天然硬石膏的活性激发情况做了分析研究。研究结果表明，加入激发剂后水化率有了显著的提高，但不同激发剂对不同产地硬石膏的激发效果不同，存在明显的差异，表明不同产地硬石膏对激发剂存在一定的适应性。

英文摘要：

Through measuring hydration rate of different age and the strength of a certain age, analysis and stud） the situation of activity stimulated that are from different areas of natural anhydrite add salt and alkaline activator. The results show that hydration rate have been significantly improved after the accession of activator. However, the excitation effect is different because of different areas of natural anhydrite to the different activator, and there are clear differences, which shows that there is a certain adaptability that different areas of natural anhydrite to the activator.
