Overview
GGBS (ground granulated blast-furnace slag) is a by-product of iron making, ground to a fine powder. Replacing 30–70% of Portland cement with GGBS lowers the carbon footprint of concrete and improves its long-term strength and resistance to chlorides and sulphates.
It is widely specified for marine works, mass concrete, ready-mix and precast.
