试验选用云南楚雄州某地稀土尾矿，以稀土尾矿部分取代黏土原料进行水泥熟料煅烧试验。试验结果表明：掺入稀土尾矿及铅锌矿烧成熟料中的f-CaO含量明显减少，生料的易烧性提高；其3 d、7 d和28 d抗压强度均有不同程度的提高；水泥熟料中的C3S、C3A和C4AF含量有所增加，对水泥熟料的烧成起到促进作用，有利于水泥熟料矿物的形成，尤其是熟料中的C3 S增加明显。

Cement clinker burning test was done by using Yunnan some rare earth tailings instead of clay raw materials.Test results show that the mixed rare earth tailings and lead-zinc mine to burn in the mature makings f-CaO content decreased significantly,the raw material is easy to burn;The three days, seven days and 28 days compressive strength increase to some extent;C3S and C3A and C4AF content of Cement clinker increase,which promote the cement clinker sintering,is beneficial to the formation minerals in cement clinker,especially the C3 S in clinker increase significantly.
