Ground granulated blast-furnace slag - Wikipedia. Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.Ground-granulated blast furnace slag is highly cementitious and …
Inter-grinding has the disadvantage of reversing the preferable order of fineness. Separate grinding of the slag and cement permits each to be ground to its own optimum fineness. The two ground materials can then be blended to produce a Portland blast-furnace slag cement with better performance characteristics than that made by inter-grinding.
After cooling to 93°C (200°F) or lower, the slag is transported to a plant for crushing and screening to a size appropriate for concrete use (Dobrowolski, 1998 ). Air-cooled blast furnace slag has been extensively used as a construction aggregate. View chapter Purchase book
