Metakaolin is a highly active artificial volcanic ash material that can react with Ca (OH) 2 (CH) and water to produce hydration products similar to cement. By utilizing this characteristic, when used as an admixture for cement, the CH reaction generated during the cement hydration process can improve certain properties of the cement.
