A blast furnace is a utility block that generates in a village's armorer houses. 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. 1 Uses 2 Crafting 3 Trivia 4 See also 5 Gallery A blast furnace can be used as a faster alternative to smelt ores. Since the discovery of the latent hydraulic reactivity of ground granulated blast-furnace slag (ggbfs) by Emil Langen at the end of the 19th century, this material has been used successfully as cement and concrete addition.
