Metakaolin, kaolinite, Dr. Denis Bezard

Metakaolin is a pozzolanic additive/product which can provide
many specific features.

Metakaolin is available in many different varieties and qualities.
The purity will define the binding capacity for free lime. Some of
them also provide special reactivity. 
Metakaolin is a valuable admixture for concrete and/or cement applications. Usually 8% - 20% (by weight) of portland cement 
replaced by metakaolin.  Such a concrete exhibits favorable
engineering properties.  The  pozzolanic reaction  starts  soon
and continues between 7 to 28 days.
