含超细矿渣水泥的水化研究

Study on the Hydration of Cement Containing Ultra fine Slag

摘要:

用ＴＧ－ＤＴＡ，ＸＲＤ，ＳＥＭ研究了超细矿渣水泥的水化反应，并与硅酸盐水泥、含普通细度矿渣水泥的水化作了比较。结果表明：超细矿渣的水化程度较快、活性较高、可大量消耗水泥浆体中的Ｃａ（ＯＨ）２，生成更多的凝胶产物，因而改善了水泥石的微观结构，提高了水泥的物理力学性能。

Abstract:

The hydration of cement containing ultra fine slag was studied and compared with the hydration of cement containing ordinary fine slag. The hydration production was analysed by TG DTA, XRD and SEM, hydraulic degrees were determined. The results show, hydraulic rate of cement containing ultra fine slag is much higher than that of cement containing ordinary fine slag. At early hydation, ultra fine slag can consumes a lot of Ca(OH) 2 in the paste and produces much of gel. The physical and mechanical properties of hardened cement paste are enhanced and the microstructure is improved.
