摘要
研究了几种单一激发剂不同掺量对钢矿粉活性的激发作用及机理,优选最佳激发剂种类及掺量。结果表明:对钢矿粉激发效果较好的激发剂为半水石膏、氧化钙、二水石膏、硫酸钠、氢氧化钠,其激发剂最优掺量分别为半水石膏0.6%、氧化钙0.15%、二水石膏0.2%、硫酸钠0.15%、氢氧化钠0.03%,其中半水石膏可提高钢矿粉各龄期活性指数8%以上。
To obtain the optimal activator,both physical performance and mechanism on the activity of steel slag and blast furnace slag power with several single activator were investigated. The results indicated that optimal activators with the best mix proportion are 0. 6% hemihydrate gypsum, 0.15% calcium oxide, 0.2% dihydrate gypsum,0.15% sodium sulfate and 0.03% sodium hydroxide. Especially, the activity index of steel slag and blast furnace slag power at each age was increased by 8% with hemihydrate gypsum.
