Hydration Properties of STS-Refining Slag-Blended Blast ...

The refining process using an aluminum deoxidizer for fabricating stainless steel generated steel slag (STS-refining slag (SRS)) that contains a large amount of Al2O3 and is a compound of mainly 12CaO·7Al2O3 and 3CaO·Al2O3. When SRS was mixed with slag cement, rapid exothermic reaction occurred in the initial phase of hydration.

Slag or Flyash – What's the difference? – BGC Cement

GGBFS is a dried and finely ground by-product of the blast-furnace iron-making process, while flyash is the fine ash residue collected from the waste gases of power generating plants. What makes these products particularly valuable is that they both develop cementitious properties when they are activated by the reaction between the cement and water mix.
