“Ground Granulated Blast Slag (GGBS) In Concrete – A Review”

This slag is periodically tapped off as a molten liquid and if it is to be used for the manufacture of GGBS it has to be rapidly quenched in large volumes of water. The quenching optimises the cementitious properties and produces granules similar to coarse sand. This „granulated‟ slag is then dried and ground to a fine powder.
