The product

What is GGBFS.

A fine, reactive powder produced by grinding water-granulated blast-furnace slag. In concrete it reacts with the calcium hydroxide released as cement hydrates, forming additional cementitious compounds with the potential to improve long-term strength and durability.

Pozzolanic reactivity

Reacts with calcium hydroxide to form additional binding compounds, supporting strength development over time.

Lower heat of hydration

Can reduce thermal stress during curing, which suits mass pours such as foundations and large structural elements.

Cost-effective cement replacement

Partially replaces Ordinary Portland Cement in the binder, with the potential to reduce material cost.

Lower carbon footprint

Potential to substantially reduce the embodied CO₂ of concrete and support green building certification.
