Metakao is engineered to provide a high-level of pozzolanic reactivity, thus enhancing concrete and cement-based product performance. METAKAO is a proven, readily available, highly reactive alternative to fly ash, slag and silica fume. 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 aluminum silicate mineral kaolin that meets the technical specifications for ASTM C-618 and AASHTO M295-11, Class N pozzolans. Our proprietary manufacturing process optimizes pozzolanic reactivity and ensures the product meets the highest standards of quality and consistency.
