Sustainable building requires innovative solutions – this is precisely where the new National annex ND of SN EN 206 comes in. It enables more flexibility in concrete production and opens up new avenues for more environmentally friendly materials. Concrete according to annex ND is defined by its properties – the key factor is what it can do, not what it is composed of.

What is different?
✅ More flexible formulations – no minimum cement content, no fixed water-cement value
✅ More circularity – greater diversity of materials from the circular economy
✅ Less CO₂ – thanks to greater freedom in choosing alternative binders
These innovations directly support the objectives of the new SIA 390/1, which defines the climate path for buildings – and thus fit perfectly with KIBECO’s philosophy. With our sustainable concretes RECO200 C25/30 XC3 (GWP phase A1-A3: 104 kg CO₂/m³) and RECO300 C30/37 XC4, XF1 (GWP phase A1-A3: 128 kg CO₂/m³) is exactly where we come in. Both grades sequester CO₂ and offer a 35% lower carbon footprint – with the same modulus of elasticity of E25 and E30.
If you would like to go one step further: KIBECO Cleancrete Oulesse NPK A C20/25 XC1 uses an innovative, circular and cement-free binder.
The ND annex opens the door to greater sustainability in the construction industry. We are ready – are you?
