Effect of Modified Argon Oxygen Decarburization (AOD ...

Abstract. The stainless steel slag of argon oxygen decarburization (AOD) is a kind of alkaline waste with cementitious activity phase, which can change the β - C 2 S to γ - C 2 S phase in the process of natural cooling and reduce the cementitious activity of the steel slag. What's worse, the large difference of the density of the two crystal phases will lead the AOD slag to pulverize.
