Uses of GGBS. The major use of GGBS is in ready-mixed concrete, and it is utilised in the majority of UK ready-mix deliveries. Specifiers are well aware of the technical benefits, which GGBS imparts to concrete, including: Considerable sustainability benefits. Lower early-age temperature rise, reducing the risk of thermal cracking in large pours.

Slag Cement, formerly referred to as ground, granulated blast-furnace slag, is a glassy, granular material formed when molten, iron blast-furnace slag is rapidly chilled - typically by water sprays or immersion in water - and subsequently ground to cement fineness. Slag cement is hydraulic and can be added to cement as an SCM.
