Tougher concrete.
A pore-refined matrix gives high resistance to chloride ingress, sulfate attack and ASR. Service life extended where it matters most: marine, mass pours, aggressive ground.
+ reduced thermal cracking in mass pours

The facility
Built right next to the slag.
One furnace, one source. Our mill draws slag directly from the adjacent blast furnace, so every batch starts from the same feedstock. The result is single-source supply with stable chemistry and a supply chain measured in metres, not shipping lanes.
Metres, not km
Slag moves across the yard, not down a highway. Furnace and mill share one industrial park.
Stable chemistry
Every tonne is milled from a single blast furnace, so composition stays consistent batch after batch.
Secure supply
Feedstock is committed at source. No reliance on traded slag of mixed or unknown origin.
From slag to powder
From 1,500 °C to powder.
Quench molten slag fast enough and it locks into a glassy, reactive state. Five stages from furnace to powder.

The chemistry of strength
Chemistry behind GGBFS.
Cement hydration produces C-S-H, the binding phase, plus Ca(OH)₂. GGBFS reacts with that Ca(OH)₂ to form additional C-S-H, giving a denser, more durable matrix.

Zooming into the particles.
Flip the toggle. Each amber Ca(OH)₂ crystal converts into additional C-S-H in place, the binder packs tighter, and the capillary pores close up.

Performance vs full OPC
What GGBFS does for concrete.
Cost-effective.
GGBFS replaces a major share of higher-priced OPC in the binder, cutting cost per m³ while improving durability and finish.
+ up to 65% of the binder, replaced
Far less carbon.
Published EPDs put GGBFS at 80–90% lower embodied CO₂ than Portland cement, tonne for tonne. Roughly 780 kg CO₂ avoided per tonne replaced.
+ circular by design · zero quarrying
Sustainability tool
Run the carbon math.
Estimate the CO₂ you’ll prevent by specifying ERSB GGBFS instead of Portland cement. It is a number your procurement and ESG teams can take upstairs.

CO₂ prevented (t) = Volume × 0.36 × (Ratio ÷ 100) × 0.79
0.36 = tonnes of cementitious binder per m³ · 0.79 = tonnes CO₂ avoided per tonne of cement replaced, consistent with published industry EPD data (~780 kg/t). Indicative estimate; project values vary with mix design.
