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. 4� � c�� $�b��X��N�� Blast furnace slag is a by-product of iron manufacturing, via thermochemical reduction, in a blast furnace. The molten slag at a temperature of about 1500°C GGBS Concrete GGBS Proportions On its own, ground granulated blast furnace slag (GGBS) hardens very slowly and, for use in concrete, it needs to be activated by combining it with Portland cement. GGBS being a waste material, it needs proper method for disposal. Concrete durability largely depends on the possible corrosion of reinforcing bars in an aggressive environment, resulting in cracking and spalling of concrete. 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.
