Steel slags in cement-based composites: An ultimate review …
Typically, steel slag is cooled slowly, influencing the high content of crystalline free CaO and crystalline iron oxide; therefore, the steel slag should be cooled quickly to reduce volumetrically unstable crystalline free CaO and crystalline iron oxide [157]. A striking feature of steel slag is the high CaO content (25 – 55% by weight) [158].
