中文摘要	本文选用浓度为1.2 mol/L和1.6 mol/L的NaOH溶液为激发剂,研究强碱性环境对钢渣水化1 d和7 d的水化产物、微观形貌及水化结合水的影响,并与钢渣在60℃时的水化性能进行了比较。结果表明:强碱性环境和高温能够促进钢渣活性组分(C2S、C3S和C12A7)的早期水化,但钢渣中的非活性组分(RO和Fe3O4)的水化程度很低;强碱环境和高温对钢渣水化的水化产物种类的影响差异很小;钢渣水化产物的化学结合水量随着碱度的增加而增大,相比于高温,强碱环境对钢渣早期水化的促进作用较大。; NaOH solutions with concentration of 1. 2 mol /L and 1. 6 mol /L were used as activators in the hydration of steel slag. The hydration products,microstructure and non-evaporable water content of steel slag hydrating for 1 d and 7 d were investigated. The hydration properties of steel slag under the alkaline condition were compared with those under the temperature of 60 ℃. The results show that both the conditions of high alkalinity and elevated temperature can promote the early hydration of steel slag's active components( e. g. C2 S,C3S and C12A7),but the hydration degree of low-active components( e. g. RO phase and Fe3O4) was very low. High alkalinity and elevated temperature had little influence on the kinds of hydration products of steel slag. The non-evaporable water content of steel slag increases with an increase in alkalinity. The promoting effect of high alkalinity on the early hydration of steel slag was stronger than that of elevated temperature.
