摘　　要：简述钢渣的基本理化性质,提出钢渣的活性判定方法,进而归纳钢渣所具有的物理激发、化学激发和高温激发三种主要激发方式。钢渣活性激发的核心思想是通过提高钢渣粉磨后的细度、提高钢渣主要矿物组分的活性以及加速其水化反应速度,从而提高钢渣用作活性矿物掺合料拌制混凝土的早期强度及耐久性能。通过归纳与总结,为今后进一步优化钢渣胶凝材料及其在水泥混凝土领域的应用提供参考。Briefly describe the basic physicochemical properties and activity determination methods of steel slag,then,three main excitation modes of steel slag including physical excitation,chemical excitation and high temperature excitation are summarized.The core idea of activating steel slag activity is to improve the fineness of steel slag after grinding,enhance the activity of the main mineral components of steel slag,and accelerate its hydration reaction rate,thereby improving the early strength and durability of steel slag used as an active mineral admixture in concrete mixing.Through induction and summary,this paper provides reference for further optimization of steel slag cementing material and its application in cement concrete field.
