• Thermally treated kaolin
• Densifies concrete and gives a better chemical resistance
• Reacts with Portlandite of the cement
• Reduced secondary efflorescence by reaction with Portlandite
• Accelerates the cement mix
• Better workability of mortars
• Better adhesion to fillers and substrate, reduces shrinkage and creep

Metaver is a calcined kaolin that reacts with the free Portlandite to form added CSH phases (calcium-silicate-hydrate; cement binder). This makes the cement matrix denser.

Its laminar form improves the thixotropy of mortars.
