Abstract
By comparing the grainability of lithium tailings,limestone and cement clinker,the influence of different content of lithium tailings and limestone powder on cement strength and fluidity of mortar was studied.The results show that the grindability of lithium tailings is better than that of cement clinker and worse than that of limestone.The influence of different dosage of lithium tailing powder and limestone powder on cement strength and fluidity of mortar is basically the same.The higher the dosage,the lower the strength,and the fluidity of mortar is slightly increased.According to the proportion of white cement clinker 61.5%+lithium tailings 35%+dihydrate 3.5%,the P·W32.5 grade white cement can be prepared in line with national standards and market requirements.关键词
