Ground calcium carbonate CaCO3


Calcium carbonate

The natural chalky rock is ground down to flour to produce calcium carbonate with particle sizes ranging from 50µ to 300µ, according to customers' requirements.

Limestone fillers

We finely grind calcium carbonate to produce limestone fillers as additives for concrete or surfacing materials. We have developed FILAFLUID®, a filler for self-levelling concretes and self-compacting concretes.
