The Carbon Cost of Slag Production in the Blast Furnace: A
The CO 2 value for granulated slag as derived above allows dividing the hot metal production into two subprocesses, one for hot metal and one for slag Conclusions The present analysis shows that the carbon footprint or carbon cost of slag on the Blast Furnace process can be estimated rather precisely by a single value of about In comparison, the production of ground granulated blastfurnace slag (GGBS) requires less than a fifth of the energy and produces less than a tenth of the carbon dioxide emissions It is well known that blast furnace slag cement (BFSC) has been manufactured by integrating GGBS with cement clinker or by separate grinding (Wang Durability Properties and Microstructure of Ground Granulated
