18、 because of raw material, fuel, and process variations.Some cement kiln dusts may contain large quantities ofcalcined feed materials, alkalies and sulfur compounds, orboth, while others may be primarily composed of uncalcinedraw feed. Many Portland cement kiln dusts are easily com-pacted and reactiv
