GGBS is produced by grinding Granulated Blastfurnace Slag to a controlled fineness. There are a number of different methods of grinding granulated blastfurnace slag. Traditionally, standard ball mills have been used, but since the early 2000s the use of roller presses and vertical mills has increased.
Fly ash, GGBS, and silica fume based geopolymer concrete with recycled aggregates: Properties and environmental impacts. ... which is one of the largest contributors to CO 2 emissions requires around 3 billion tons of raw material and 4700 MJ / ton of energy and is expected to expand by 4 % every year [2].
The specific grinding energy E m is the specific impact energy Ei m = Ei/M multiplied by the number of impacts N i = ft during the grinding time t. Hence, (4) E m t = Ei M N i = 16 m b Aπ 2 f 3 t M Note that the assumptions underlying this relation hold at weak filling ratio where the motion of the ball is not limited by the amount of material ...

GGBS is an excellent supplementary cementitious material that helps displace clinker demand globally. However, GGBS is a limited and constrained resource that is almost fully utilised globally. Therefore whilst global supplies must continue to be fully utilised, locally increasing GGBS use is unlikely to decrease global emissions.
