Research Progress on Activation of Steel Slag Pozzolanic Activity
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 temper-ature 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.
