摘要
本文以天然硬石膏为原料,用硫酸钠、硫酸氢钠、碳酸钾、硫酸钾、氧化钙和复合激发剂FG为激发剂,分别测试硬石膏的3d水化率。结果表明:硫酸氢钠激发水化效果好于硫酸钠;硫酸钾的激发水化效果好于碳酸钾;在这几种激发剂中,复合激发剂FG的激发水化效果最好,FG加入3%时,3d水化率达到63.8%。
In this paper,three-day hydration rate of natural anhydrite was determined,using sodium sulfate,sodium hydrogen sulfate,potassium carbonate,potassium sulfate,calcium oxide and composite FG as activating agents.The results showed that the efficiency of sodium hydrogen sulfate is higher than that of sodium sulfate,while potassium sulfate is more efficient than potassium carbonate.Among these activating agents,the one of composite FG exhibited the highest efficiency.The three-day hydration rate was determined to be as high as 63.8% when 3% of composite FG was added.
