摘　　要：研究利用泥灰岩和铜锌尾矿代粘土烧制水泥熟料。通过实验室对生料易烧性试验和ＤＴＡ分析，并对试验熟料进行ＸＲＤ、早期水化放热和岩相分析，探讨泥灰岩和铜锌尾矿的异组分对熟料矿物形成及其结构的影响。研究及生产应用的结果表明，利用泥灰岩和铜锌尾矿配料，可改善生料的易烧性，有利于熟料矿物的形成，增产节能显著。This is a research on using marl and tailings from copper are and zinc ore to produce low energy consumption cement. Through DTA testing on raw meal burn ability , XRD on clinker analysis, heat evolution determination and petrographic analysis on early stage hydration, the authors discussed the influence of foreign components of marl and tailings on the formation and structure of clinker minerals. The results reveal that using marl and such tailings can improve the raw meal burn ability and clinker mineral formation, to increase the output and improve the energy saving.
