metakaolin
Sign in to saveAlso known as metakaolinite
Metakaolin is the anhydrous calcined form of the clay mineral kaolinite. Rocks that are rich in kaolinite are known as china clay or kaolin, traditionally used in the manufacture of porcelain. The particle size of metakaolin is smaller than cement particles, but not as fine as silica fume.

Metakaolin is the anhydrous calcined form of the clay mineral kaolinite. Rocks that are rich in kaolinite are known as china clay or kaolin, traditionally used in the manufacture of porcelain. The particle size of metakaolin is smaller than cement particles, but not as fine as silica fume.
== Kaolinite sources == The quality and reactivity of metakaolin is strongly dependent of the characteristics of the raw material used. Metakaolin can be produced from a variety of primary and secondary sources containing kaolinite: metakaolin is a dehydrated form of kaolinite, a type of clay mineral. Kaolinite-rich minerals are also referred to as china clay or kaolin, which are traditionally utilized in the production of porcelain. High purity kaolin deposits Kaolinite deposits or tropical soils of lower purity Paper sludge waste (if containing kaolinite) Oil sand tailings (if containing kaolinite)
