为了分析水泥-锂渣浆体的水化程度,采用高温煅烧法测试各龄期的化学结合水,结果发现：水泥-锂渣浆体的化学结合水量随龄期的延长而增加,水化3 d和7 d时能达到水化90 d时的60%和80%。高温养护、碱激发、高温和碱激发均能提高锂渣复合水泥基材料早期的化学结合水量,最高可达3-4倍,提高的幅度依次为碱激发和高温养护〉碱激发〉高温养护〉标准养护。高温和复合环境养护也能提高水泥的水化程度,1-28 d内,锂渣掺量在40%以内时,水泥水化程度相对指数（ψ值）均大于1;掺量为60%时,ψ值均小于1。综上,高温养护、碱激发、高温和碱激发均能提高锂渣和水泥的水化程度,高温和碱激发复合作用时较为显著。

英文摘要：

In order to analyze the hydration degree of the cement-lithium slag slurry,the chemically combined water is tested by high-temperature calcination at different ages. The testing results show that the chemically combined water of the cement-lithium slag slurry increases with prolongation of the age that can be able to achieve more than 60% and 80% for 90 d at 3 d and 7 d hydration degree,after then this increase becomes slower. The chemically combined water at 1 d is up to 3 to 4 times under the conditions of high temperature curing,alkali activation,high temperature and alkali activation（ composite curing）,which is better than standard curing.Relatively speaking,the effect of the 4 kinds of curing is in the order of composite curing 〉alkali activation〉 high temperature curing 〉 standard curing. The chemically combined water of unit cement at 1 ~28 d is small by an equivalent chemically combined water method,the relative index（ ψ value） of the cement hydration degree at 1 ~28 d is greater than 1 when the content of the lithium slag is less than 40%,and ψ value is less than 1 when the content of the lithium slag is 60% under high temperature curing and composite curing. In summary,the hydration degree of the cement and lithium slag can be improved by high temperature curing,alkali-activation and composite curing,and it is more significant in the composite curing period.
