metakaolin is a largely amosphous dehydration product of kaolinite. during the proper calcination process of kaolinite, Dehydroxylation leads to the metakaolin state according to the following reaction.
the effective kaolin was shown the highest pozzolanic properties when treated as the fllowing condition
kaolin obtained from ranong province (southern of thailand)
thermally activated at 800 in 6 hours
to investigate the use of Metakaolin from thailand as cement replacement on the compressive strengths and various properties related to durability of motar.
