| 摘 要： | 钢渣是炼钢过程中产生的废渣,高碱度钢渣中含有较多的C3S和C2S,因而具有一定的胶凝活性,可用于生产钢渣水泥.但高碱度钢渣中游离氧化钙含量较高,使钢渣水泥的安定性不良.必须对钢渣进行适当的处理,解决其安定性问题,并通过机械或化学的方法激发其活性.本文对钢渣膨胀的诱因与抑制措施、活性激发等问题进行了详细的探讨.

| Abstract: | Steel slag is a kind of industrial waste slag produced during the process of melting steel.Steel slag with higher basicity has potential hydraulic reactivity,because of its higher content of C3S and C2S.Therefore,it can be used in steel slag cement.However,the content of f-CaO in steel slag increases with increase of its basicity resulting in poor volume stability.Consequently,steel slag needs to be pretreated to improve its volume stability and its activity should be activated by mechanical or chemical methods.The inducement and restraint of voluminal expansion when steel slag was used in cementing area as well as the motivation of steel slag activity were discussed in detail. |
