GBF SLAG
1
Description of GBF Slag : 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 high in CSH (calcium silicate hydrates) which is a strength enhancing compound which improves the strength, durability and appearance of the concrete.
Application of GBF Slag:
GBF Slag is used to make durable concrete structures in combination with ordinary Portland cement for its superiority in concrete durability, extending the lifespan of buildings from fifty years to a hundred years.
