简要地分析了磷酸盐矿物的地质特征和结构特征，并详细分析了安哥拉罗安达水泥厂含磷石灰岩矿床的化学组成、磷和氟含量及其矿物特征和形貌。在此基础上，重点试验研究了P2O5对水泥生产和熟料性能的影响情况。试验结果初步显示：（1）含磷高的原料对熟料的烧成和产品性能影响很大，因P2O5既会影响水泥熟料矿物C3S的形成，还会阻碍水泥的早期水化，严重影响水泥的凝结和硬化过程；（2）熟料中当w(P2O5)＜2.0%时可以制备性能满足要求的水泥，在生产控制中要严格控制生料中w(P2O5)＜1.0%[石灰石中w(P2O5)＜0.8%]为宜；（3）在含磷熟料中，适量F-的存在[w(F-)＜0.35%]能降低P2O5的负影响。

The geological and structure characteristics of phosphate minerals were analysed in brief, and chemical composition,con-tents of phosphorus and fluorine and its mineral characteristics and morphology of phosphorus limestone mineral of Angola Luanda Ce-ment Plant were analysed in detail. On that basis, the effect of P2O5 on cement production and clinker property was laied stress on.And the results show as follow, (1) high phosphorus raw material has great impact on clinker calcination and production properties, as P2O5 can not only hinder the formation of C3S and delay cement early hydration which affect greatly cement setting and hardening process. (2) qualified cement can be produced when P2O5 content in clinker is less than 2.0%, and in real production, w(P2O5) in raw material should be controlled at less than 1.0%(in limestone, w(P2O5)<0.8%);(3) for phosphorus clinker, a proper amount of fluorine [w(F-)<0.35%] can mitigate the negative effect caused by P2O5.
