摘　　要：针对Ａ、Ｃ两种尾矿，初步研究了微量元素对熟料矿物早期水化性能的影响。发现微量元素的参与抑制了Ａｌｉｔｅ的早期水化，认为这种抑制是尾矿中的某些离子与水化产物Ｃａ（ＯＨ）＿２形成无定形氢氧化物沉淀的结果，进而提出了Ａｌｉｔｅ早期水化机理模型。Regarding tailings A and C,the effect of minor components on the early hydration of cement clinker was studied.It was found that some ions present in tailings inhabited the early hydration of Alite because of forming amorphous hydroxide precipitates by reacting with the hydration product Ca(OH)_2.Meanwhile,the early hydra-tion mechanism of Alite was supposed.
