Global Slag
Slag from different regions in the world varies in general composition with slag from Asia being high in alumina slag from North America being low alumina and Russian and Eastern European slags tending to have low alumina and with C/S being medium to high. With increasing C/S ratio the strength of the final product tends to increase.

Production of special cement types Mixing of slag with diasporic bauxite and limestone can lead to the production of alluminic cement. This is a high price material because of its properties that is high initial strength (strengthening comes in one day versus 30 days for Portland cement) high erosion resistance and refractoriness.

Abstract This paper evaluates the fresh and hardened properties of cement pastes and mortars blended with a ground granulated high-magnesium ferronickel slag (FNS). The main elements of the slag are Silicon (Si) Magnesium (Mg) and Iron (Fe). Test results show that water demand and setting times were not significantly changed by use of the FNS as cement replacement up to 50 .
