    Metakaolin (MK) is known to be a highly pozzolanic material that can be used in concrete MK is usually produced by heating kaolincontaining clays, within the temperature range of about 600–900 ℃ This chapter summarizes the utilization of metakaolin in relevant worldwide standards, mainly in Europe and North AmericaThe results indicate that a metakaolinbased geopolymer is a technically feasible alternative for removing NH 4 + from wastewater Metakaolin itself is a poor NH 4 + adsorbent, but geopolymerization substantially increases the NH 4 + removal capacity (600–900%) 2 Materials and methods21 Synthesis of the geopolymerMetakaolin geopolymer characterization and application
