What is GGBS?
GGBS (Ground Granulated Blast-furnace Slag) is a cementitious material whose main use is in concrete.
Uses of GGBS
The major use of GGBS is in ready-mixed concrete. It is utilised in the majority of UK ready-mix deliveries.
GGBS Concrete
On its own GGBS hardens slowly and, for use in concrete, it needs to be activated by combining it with a source of free lime, usually Portland cement.
Sustainability
GGBS is one of the ‘greenest’ of construction materials. Its only raw material is a very specific slag that is a by-product from the blast-furnaces manufacturing iron.
