Environmental Impact

  • cement-free
  • up to 90% C0₂ reduction
  • up to 98% up-cycled excavation material
  • 2-4 MPa compressive strength
  • low energy intensity


  • internal non-load bearing walls
  • screed
  • terrazzo flooring
  • furniture
  • cast elements
  • composite applications with wood
  • particularly recommended for applications where formwork must be removed quickly and for tall cast elements

Nossim vs. Care

For application requiring a fast early age strength independent of the drying process, the admixture Oxacrete Nossim is more suitable.


Concrete based on Oxacrete Nossim is produced, transported, and processed like conventional concrete, requiring no extra infrastructure or machinery. Making the adaptation of sustainable practices easy.
