中文摘要：

锂渣是新疆大量排放的固体工业废弃物，作为活性掺合料应用于混凝土中，一方面可减少其排放和堆存量，有利于改善环境；另一方面，锂渣粉也能有效改善和提高混凝土的性能。通过研究不同比表面积的磨细锂渣粉对混凝土新拌性能的影响。从凝结时间、坍落度保持、常压泌水率和压力泌水率的试验结果综合，比表面为597m＾2／kg的磨细锂渣粉取代混凝土中水泥量在10%－30％时，对混凝土新拌性能改善最为明显。

英文摘要：

Lithium slag is a large quantity of solid wastes in Xinjiang, the concrete with lithium slag powders as the mineral admixture can reduce pollution of the solid wastes.On the other hand, and lithium slag powder also can effectively improve the performance of concrete.Study on the influence on fresh concrete with ground granulated lithium slag;the specific surface area of 597 m^2/kg of ground granulated lithium slag powders on concrete substituting lithium slag powders on the amount 10%-30% for cement.The results indicated that lithium slag powders can effectively improve the performance of fresh concrete.
