Metakaolin additive

METAKAO premium metakaolin additive is engineered to provide a high level of pozzolanic reactivity to enhance concrete and cement-based product performance.

Performance beyond standard pozzolans

The METAKAO additive reacts with the free lime in Portland cement to increase the formation of calcium silicate hydrate (CSH). The additional CSH formed increases the cementitious bonds in concrete to make it stronger, more durable and less porous.

Engineered for increased pozzolanic reactivity

METAKAO additive is an ultra-fine material produced from the aluminium silicate mineral kaolin. Our proprietary manufacturing process optimizes pozzolanic reactivity and ensures the product meets the highest standards of quality and consistency.
