Steelmaking Slag - an overview ScienceDirect Topics

2012-4-4  Nonetheless, more approaches for the use of steel slag are still under seeking. It is found that under CO 2 rich environment, the steel slag is very carbonation reactive, and hence has a big potential to be used as the feedstock for CO 2 sequestration. This has attracted increasing attention from researchers and abundant work has been focused on this.
