CSTB has validated an ATEX Case A for Materrup flooring


CSTB has validated an ATEX Case A for Materrup flooring 

Another significant milestone has been achieved to enable the construction of flooring in ready-mix concrete (RMC) with consistent performance, thanks to our high environmental value MCC1© non-calcined clay cement, type 42.5.


Key points to remember:

  •  For low-carbon C25/30, C30/37, and C35/45 concrete
  •  Same cement dosage and steel reinforcement proportion
  •  Materrup MCC1® concrete exhibits mechanical strengths comparable to conventional concrete.
  •  The steel-concrete bond stress is comparable to that of conventional concrete.
  •  The implementation of Materrup MCC1® concrete is similar to that of conventional concrete.


Thanks to our CCC© technology, our cement solutions remain:

🌱 -50% CO2

♻️ Derived from the circular economy

🧭Locally manufactured in a short supply chain
