durability of kaolinite
The durability is the ability of concrete to resist weathering action, chemical attack, and abrasion while maintaining its desired engineering properties.

Due to the denser binder matrix and the reduced chemical and physical deterioration the durability of cementitious systems is greatly increased.

Depending on the application an engineer must design a concrete of different degrees of durability and properties which depend on the exposure given by the environment, e.g. water, salt water, etc.

With  metakaolin  the  durability  can  be  improved  to the needed  levels to find the suitable durability  to  extend the life time of a concrete, according to the exposition classes as defined in EN206.
