Nk'ubwoko bw'ibikoresho by'ivu ry'ibirunga, metakaolini ni ikintu cyiza cyane cyasimbura sima bitewe nuko ikoresha ingufu nke kandi ihumanya ibidukikije bike mu gihe cyo gukaranga, ndetse n'ubushobozi bwayo bwo kunoza imiterere imwe n'imwe ya sima ya Portland, nko gukomera no kuramba, iyo ikozwe muri sima ivanze. Mu myaka ya vuba aha, intiti nyinshi zibanze ku kwiga imikorere y'ivu ry'ibirunga rya kaolini. Iyi nkuru igaragaza ubushyuhe bwiza bwa kaolini n'igihe cya kaolini, ibintu bigira ingaruka ku bikorwa byayo, n'uburyo bwo kumenya imiterere n'imikorere ya kaolini. Ubushakashatsi bwabanje bwagaragaje ko ubushyuhe bwiza bwa kaolini n'igihe cya kaolini bigengwa n'ibintu nk'imiterere y'amabuye y'agaciro, ubutare, n'ingano ya kaolini, muri byo harimo ubutare bwa kaolini bufite ingaruka nini ku bikorwa byayo nyuma yo gukaranga. XRD, TG-DTA, IR n'ubundi buryo bwakoreshejwe mu gusesengura imiterere y'amabuye y'agaciro. Umurimo wa kaolini wagenwe binyuze mu buryo nka Frantini test, conductivity test, na strength activity index. Uburyo bwiza cyane ni Frantini test na strength activity index test.
Metakaolin (mu magambo ahinnye nka MK) ni silicate ya aluminiyumu idafite amazi (Al2O3 • 2SiO2, AS2) ikorwa no kubura amazi kwa kaolini (Al2O3 • 2SiO2 • 2 H2O, AS2H2) ku bushyuhe bukwiye (600-900 ℃). Kaolini igize imiterere ya silicate ifite ibice, kandi ibice bifatanye na van der Waals bonds, hamwe na OH - ions zifatanye neza muri yo. Iyo kaolini ishyushye mu kirere, ihinduka mu buryo butandukanye. Iyo ishyushye kugeza kuri 600 ℃, imiterere ya kaolini ifite ibice irangirika bitewe no kubura amazi, bigatuma habaho ihinduka ry’imiterere ifite ubushyuhe buke - metakaolini.
Bitewe n’imiterere idahwitse ya metakaolini, igaragaza imiterere ihindagurika ya thermodynamic kandi igaragaza imiterere ihamye ya sima iyo ishyushye neza. Metakaolini ni ivu ry’ibirunga rikora cyane rishobora gukorana na Ca (OH) 2 (CH) n’amazi kugira ngo rikore ibintu bitoshye nk’isima. Iyo ikoreshejwe iyi miterere, iyo ikoreshejwe nk’uruvange rwa sima, ishobora gukorana na CH ikorwa mu gihe cyo gukora sima, ibi bikaba bishobora kunoza imiterere imwe n’imwe ya sima.
Metakaolin (MK) ni umusaruro ukorwa no kubura amazi muri kaolin ku bushyuhe bwinshi, kandi ubushyuhe bwa calcination bushobora kugira ingaruka ku mikorere y'umusaruro.
Iyo ubushyuhe burenze 950 ℃, umusaruro utangira gushonga no guhinduka mullite na cristobalite,
Izatakaza ubushobozi bwayo bwo guhumeka.
Kaolini ya Calcined ni ikintu gikoreshwa cyane mu nganda zikora ibikoresho bya polymer nka rabber, pulasitiki, n'amabara. Bishobora kugabanya ikiguzi cy'ibi bicuruzwa, cyane cyane kunoza imiterere y'ibinyabutabire n'imiti by'ibikoresho.
