钢渣活性激发的机理及研究进展

Mechanism and Recent Development of Steel Slag Activating Activity

钢渣的化学组成与水泥熟料相似,且高碱度钢渣中含有较多的C3S和C2S,具有一定的胶凝活性,可以直接作为掺合料生产钢渣水泥,但是其较低的活性成为制约钢渣利用的关键问题。对钢渣活性较低的原因、活性激发的机理及研究进展进行了详细的探讨,如机械激发、化学激发、热力学激发、钢渣重构等。

Chemical composition of steel slag is similar to cement clinker,and steel slag with higher basicity has potential hydraulic reactivity,because of its higher content of C3S and C2S.Therefore,it can directly product slag cement as admixture,but there is a problem that it has a lower activity as the admixture to produce slag cement.The reasons for lower activity of steel slag,mechanism and development of steel slag activating activity are discussed in detail,such as mechanical,chemical,thermodynamic excitation,reconstruction of steel slag,and so on.
