中文摘要：

对某水泥厂存在“欠烧”和“过烧”情况的两种熟料进行岩相分析，并结合其化学分析探索主要成分变化规律及形成原因。分析表明：欠烧状态下熟料结构多孔、且孔洞尺寸大，C2S簇和f-CaO簇呈较近距离分布；而过烧状态下熟料结构致密，C3S矿物之间分布一些f-CaO单晶体或小尺寸的簇，周围没有可与之反应的C2S矿物。

英文摘要：

Phase structure of soft-burned and hard-burned clinker samples in a cement plant was analyzed, and combined with its chemical analysis to explore variation and causes of the main components. It results showed as followings： there were more pores in the soft-burned clinker sample structure, the pore size was large, the distance between C2S and f-CaO cluster was much close, and the hard-burned clinker sample＇ s structure was compact, and there were somef-CaO monocrystal and small clusters among the C3S miner- al, and there was no C2S minerals around them.
