Metakaolin is a material shaped from a natural raw-material Kaolin by calcination at above 500°C. It is a transition metastable phase. On the contrary to the mineral kaolin, the Metakaolin shows a very little expressive crystal structure similar to Kaolin – it has more or less amorphous character. At the same time a partial consolidation caused by dehydration of the original material shows up.
|MetaCem 85C||Is thermally structured, ultrafine Pozzolan which can replace industrial by-products such as fumed silica or Microsilica.|
|Metakaolin KM 60||Is used as an additive to refractory materials, concretes and mortars, as a filling agent to rubber and plastics as well as for further applications.|
|ARGICEM||A type II of pozzolanic addition to concretes and mortars.|
