Abstract

the present invention relates to a method of making a highly reactive pozzolan, involving the steps of forming a slurry comprising metakaolin and a liquid; wet milling the slurry; and separating the metakaolin from the liquid to provide the highly reactive pozzolan. The highly reactive pozzolan produced, can be combined with at least one cementitious material to make a cement-based composition, or with at least one geopolymeric material to make a an alkali-activated composition.
