in a physical form that makes it available to cement to react.

In very dry mixes, as vibrated precast stones, this water will increase the portion of cement that

has completely reacted leading to higher mechanical strength.

To keep good workability some plasticizer and water reducers have to be added.  Due to the

good water retention the bleeding tendency of concrete will be reduced or avoided.

Metakaolin particles are small plates which give the mix strength, but under shearing forces

the mix will become fluid as the metakaolin plates will line up parallel (smoothing effect).

Besides the standard processes it will also give spray mortars the internal strength to stay in

place immediately with high cohesion.
