The iron and steel industry is an energy-intensive sector, and large amounts of waste/ by-products are generated during the steelmaking process, such as CO2, metallurgical slag, and wastewater. Enhancing the development and deployment of treating waste from the steelmaking process will be environment friendly and resource-saving. Capturing CO2 by …

Mill scale is used as a source of iron during the production of steel and iron from scrap. When heated in a submerged arc furnace, very little slag is produced. When heated in a submerged arc ...

The steel mill scale is also known as steel slag, which is a byproduct of the casting and hot rolling of steel billets and slabs and water sprays separate it. Primary …

Wang et al. [140] investigated the cement properties of super-fine steel slag obtained by mechanical grinding with the results of ordinary steel slag, fly ash, and …

During steel production, the impurities in the hot metal react with the fluxes forming the steel slag. Chemical constituents of this steel slag (SS) are relevant to iron/steelmaking or blended cement manufacture. Harmful impurities present in it, however, limit its recycling to these applications. Japan, Europe, and the US consume a significant …

Steel slag has a great potential application in cement and concrete production, for the reason that steel slag contains hydraulic components, such as C 2 S and C 3 S. But f-CaO and f-MgO in steel slag will cause poor volume stability and RO phase with little hydration activity has relatively high content in steel slag [[22], [23], [24]].
