Our Product

A high-quality
SCM,
recovered — not mined.

Dureco's cement stone filler is a fine, reactive supplementary cementitious material recovered directly from concrete demolition waste — a sustainable alternative to dwindling fly ash supplies and virgin limestone filler.

Dureco SCM — recovered cement stone filler
Dureco SCM
Cement stone filler · 0–30 micron

What is our
SCM?

When the Balista Crusher separates concrete rubble, the cement stone fraction is extracted as an ultra-fine powder — between 0 and 30 microns. This material has already reacted once with water, giving it a unique, highly circular and rounded grain structure with a large surface area.

The result is a supplementary cementitious material (SCM) that can partially replace clinker in cement production — reducing CO₂ emissions, cutting costs, and offering a reliable local alternative as fly ash supplies disappear from the European market.

Material Properties

Why our SCM
performs.

🔄
Pre-Reacted Structure
Already hydrated once as cement stone, giving it a fine, porous structure that supports pozzolanic reactivity in new mixes.
⚪
Round Grain Shape
High circularity increases surface area and improves workability and packing density in cement and concrete blends.
🌍
Lower Carbon Footprint
Every tonne of SCM that replaces clinker avoids approximately 0.8 tonnes of CO₂ from cement production.
📉
Fly Ash Replacement
As fly ash supply collapses across the EU due to coal phase-out, Dureco SCM offers a reliable, local alternative.
🏭
Consistent Supply
Produced continuously at every Dureco installation — a predictable, scalable supply as our machine fleet grows.
🧪
Lab-Verified Quality
Sieve analysis and roundness testing confirm consistent particle size distribution and reactivity potential.

Applications

Where our SCM
can be used.

Under current guidelines, up to 10% of a cement mixture can be supplemented with filler — making cement production cheaper and more CO₂-neutral.
