铜尾矿对水泥生料易烧性及水泥强度的影响

Influences of Copper Tailings on Burnability of Cement Raw Meal and on Cement Strength

本文研究了利用铜尾矿全代铁粉和部分取代粘土、石灰石配料时，铜尾矿对水泥生料易烧性及水泥强度的影响。结果表明，利用铜尾矿配料可明显改善生料的易烧性，对水泥强度的影响为早期强度较低，但后期强度较高。

This paper studies the influences of copper tailings on the burnability of cement raw meal and on cement strength when copper tailings are used to replace iron cinders wholly and clay and limestone partly in the mix. The results show when copper tailings are used in the mix the burnability of cement raw meal can be improved obviously and the influences on cement strength are that the eary strength is relatively low while the late strength is relatively high.
