摘　　要：采用强度指数法、选择性溶解法、结合水率法、TG-DTA同步热分析等检测手段,评价对比了锂渣与粉煤灰、煤矸石、花岗岩粉等几种常用硅铝质材料的火山灰活性。结果表明,锂渣在四种硅铝质材料中活性指数最高,对Ca(OH)2的消耗能力最强,显示锂渣具有优良的火山灰活性。The pozzolanic activity of several common silicon-aluminum materials such as the lithium tailings, fly ash, coal gangue and granite powder were evaluatedby intensity index method, selective dissolution method, combined water rate method and TG-DTA synchronous detection. The results show that the lithium railings has the highest activity index and strongest reaction ability with Ca（ OH）2 in four kinds of materials, and prove that lithium railings has fine pozzolanic activity.
