Mineralogical and Micro-Mechanical CharacteriÂzation of Slags – Investigated on the Example of a MnSiFe Slag from Electric Arc Furnace
Recently, the recycling of metallurgical residues, e. g., electric arc furnace slag, has gained increasing importance. The potential of metallurgical slags often lies, in addition to the metallic value content, among other things in their use as aggregates for the construction industry, e. g., cement industry. The development of this potential requires…
