[Technical Equivalence Validated] A New Milestone for Our MCC1 Cement: The ETPM Is Now Available!

We are pleased to announce the official inclusion of the ETPM* (technical data sheet) for MCC1 cement, validated by the CSTB, in full technical equivalence with conventional CEM-type cements under the NF EN 197-1 standard on key performance criteria.

💡 Key Takeaways:

Concrete made with MCC1 cement demonstrates equivalent performance to concrete made with conventional cements in terms of:

✅ Creep and total shrinkage

✅ Post-peak and cyclic compression behavior

✅ Steel/concrete bond strength (static and cyclic)

✅ Cold joint performance

✅ Cement equivalent to a 42.5 at equal dosage

✅ Validated strength classes:

• C25/30 and C30/37

• C35/45

✅ Exposure classes:

XC4 / XF1 / XF3 / XS2 / XD3f / XA2

✅ Validated alkali-silica reaction resistance: PR aggregates are compatible.

🎯 This technical recognition confirms that cold-activated clay-based cement technology can play a central role in decarbonizing the cement industry, while meeting performance, durability, and ease-of-use standards.

We demonstrate that it is possible to produce locally, using quarry waste, while delivering results aligned with market expectations.

👉  This is not a niche cement, but a scalable, industrializable solution ready for large-scale deployment.

It’s a small but foundational step toward more sustainable, local, and responsible construction

🙏 Thank you to the entire Materrup team — technicians, engineers, operators — for their dedication, precision, and collective effort.

And a special thanks to CSTB for their support through this key milestone.
