After the alkalis are removed, the cement kiln dust can be blended with clinker to produce acceptable cement, and cement kiln dust can be added to portland cement with other materials such as slag and fly ash. Other natural pozzolans exist such as volcanic ash, opaline chert and shales, tuffs, and diatomaceous earths.
Adding GGBFS during cement production can increase the strength 28D of cement by 15% - 20%, to admix 42.5 grade cement, and during concrete production, slag powder can replace 10 ~ 50% of the cement, to mix C20 ~ C60 concrete, which has become an important measure to reduce the cost of cement in the international cement industry.

The NewCem® Slag Cement Advantage. To produce quality slag, a producer needs to have slag with an ideal chemistry from a consistent source and needs to have equipment close to the slag source to provide rapid quenching of the slag. Lafarge engineers and scientists have led North America in the research and development of specifications for slag.
manganese ferroalloy industry includ e an alloy and slag. Some of the alloys produced in the manganese ferroalloy industry are silicomanganese (SiMn), medium-carbon ferromanganese, and high-carbon ferromanganese (HCFeMn). These have monetary value, whereas the slag is classified as a hazardous waste product due to its MnO content (25-30 wt.%).
