Metakaolin is used as a key additive to concrete. Imerys launched its commercialization under the brand Argical™ M1000. Metakaolins’ specifications allow replacing a high quantity of cement without altering concrete performance. Imerys delivers Argical M1000 as a white color product. Customers appreciate the product as it may easily be added to concrete formulation and associated to color pigments.
The Bacalan bridge in Bordeaux may be considered as a flagship construction of Argical M1000. The 4 pylons were built with the proportional mix metakaolin – cement in order to recall the color of the buildings of the city of Bordeaux.
