    The results showed that it was feasible to use phosphorus slag to produce cement clinker, while with the increasing of the P2O5 content the C3S in clinker would be decomposed, and the P2O5 may form αC2S·C3P with C2S, thus decrease the early strength and cause the bad soundness of clinker.
    研究结果表明,使用磷工业废渣配料生产水泥熟料在技术上是可行的,但P2O5含量增加会使熟料中C3S分解产生fCaO,并与C2S形成αC2S·C3P,从而使熟料的早期强度降低,安定性不良。 高温下氟和P2O5反应形成氟磷灰石,可减少P2O5对熟料的不良影响。
