Hydration Properties of STS‐Refining Slag‐Blended Blast Furnace Slag Cement [PDF]
Advances in Materials Science and Engineering, 2018 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. During the hydration of
