Study on using steel slag as a raw meal component for cement clinker

Steel slag was ground to the specific surface area of 340 - 590m²/kg. The raw meal cooperated with certain steel Slag was burnt for 30 min at 1450 °C. f - CaO content and physics properties of clinker were determined. The experiment results indicate that cooperating appropriate amount of steel slag in the raw meal can not only reduce f - CaO content of clinker, but also can improve the quality of clinker becourse of its seed effect.
