Ultrafine GGBS — A Different League

GGBS is good. Ultrafine GGBS is a different league. Finer particles, superior performance — engineered for M50+ and ultra-high-performance concrete.

Finer Particles. Superior Performance.

Both come from the same sustainable slag — the difference is in the grind. Ultrafine GGBS is micronized to a much finer particle size than normal GGBS, unlocking faster reactivity and a denser concrete microstructure.

Normal

GGBS

Standard particle size — the proven workhorse for up to 70% OPC replacement across RMC, buildings, roads and mass concrete.

General concrete, mass pours

Enhanced

Ultrafine GGBS

Micronized fine particles — engineered for high-performance concrete where early strength and density are critical.

Higher

Best For

M50+ & UHPC concrete

Faster Reactivity

Finer particles react quicker in the mix.

Better Particle Packing

Fills micro-voids for a denser matrix.

Higher Early Strength

Faster demoulding and cycle times.

Denser Microstructure

Lower permeability, longer life.

This Is Why Ultrafine GGBS Is Preferred In:

Precast Today. Perfect Tomorrow.

High early strength, superior finish, dimensional stability, longer life & durability.

Powering Ultra High-Rises

Higher strength and reduced shrinkage & creep for the tallest structures.

Built for the Fast Track

Consistent quality for precast segments, piers and track infrastructure.

Engineered for Harsh Environments

Dense microstructure resists chlorides and sulfates for generations.

High Performance Concrete

The enabler for M50+ and ultra-high-performance concrete mixes.
