KAOPOZZ아르 자형 metakaolin is made by high quality kaolin as raw material, through several purifying processings and under a given calcined condition. It is of high pozzolanic reactivity and it gained the reputation of super pozzolana.
KAOPOZZ아르 자형 can react with calcium hydroxide which is the outgrowth of Portland cement in the course of hydrating, and produce a new colloidal material so as to enhance obviously the performance of concrete and mortar.
