摘　　要：文中研究了“氯盐压煮法”锂云母提锂渣的火山灰活性,比较了单掺锂渣和矿渣、复掺锂渣和矿渣、复掺改性锂渣和矿渣对白水泥强度的影响,利用石灰改性锂渣与矿渣复合,制备出了混合材总掺量高达70%、强度等级达到32.5级的少熟料白色复合硅酸盐水泥。The pozzolanic activity of lithium extraction slag from lepidolite using the"chlorine salt pressure cooking method"was studied,and the effects on the strength of white cement were compared between the single addition of lithium slag and slag,the compound addition of lithium slag and slag,and the compound addition of modified lithium slag and slag.By combining lime-modified lithium slag and slag,a low-clinker white composite Portland cement with a total mixed material content of up to 70%and a strength level of 32.5 was prepared.
