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. Details. 2. A Technical Advisory Group (TAG) was set up to bring together representatives from the Environment Agency, WRAP and industry. iron ore, iron sintering). A typical combination is 50% GGBS with 50% Portland cement, but percentages of GGBS [4] anywhere between 20 and 80 % are commonly used. Production of Portland blast-furnace slag cement began in 1910, and the Japanese national standard for Portland blast-furnace slag cement (JES 29) was formulated in 1926.some of the study has been done in past which summa-rized as: 1. blast-furnace slag cement.
