A steel‐making slag (basic oxygen furnace) obtained from the Kardemir Steelworks was modified to be used as a clinker additive in the cement industry. This study confirmed that the compressive strength values of concretes produced by addition of these steel‐making slags up to 30 mass% were within the values of Grade‐325 and Grade‐425 steel‐making slag cement. This is an attractive alternative for cement manufacturers, because calcined material is expensive, and slag substitutes are very often cheaper, in addition to its low or zero‐greenhouse‐gas emission.
