Oxacrete Oulesse® is a mineral binder designed for circular and low-carbon concrete products. It’s made by combining a cement-free activator with finely milled construction demolition waste – basically, we turn what’s usually trash into a valuable building material.

Thanks to its hydraulic properties, the Oulesse® binder behaves similarly to traditional cement: it develops strength over time, bonds aggregates, and works with the standard concrete production infrastructure. Plus, it enables the reuse of recycled concrete aggregates, pushing circularity to the next level.

Why Oulesse®?

• Cement-free – zero clinker

• Up to 60% CO₂ reduction compared to CEM I cement

• Up to 60% reused demolition material per ton of Oulesse - Circular by design

• Hydraulic binder – similar strength development to cement

• Fully compatible with today's concrete industry infrastructure

Applications

• Lean concrete (e.g. as base layer for foundations)

• Pavers & Tiles

• Screeds & Terrazzo flooring

• Internal load bearing concrete walls & slabs

Built together with our partners

We don’t just develop cement-free binders - we bring it to life together with experienced production partners. Thanks to these collaborations, our technology is already being used in a variety of products - from lean concrete and structural elements to CO₂-reduced pavers and tiles, as well as Terrazzo flooring and screeds.

The result? Circular, low-carbon building materials are no longer experimental – they’re being produced and distributed by trusted industry players and are ready to build with.
