Metakaolin, chinhu chine kaolin chakagadzirwa ne calcium yakawanda, chiri kuwedzera simba repasi rose sechinhu chinowedzera simba rekusimbisa (SCM) uye chinobatsira pakuvaka, mainjiniya ezvakatipoteredza, uye kugadzira zvinhu zvepamusoro. Tsvagiridzo dzichangoburwa uye miedzo yekutengeserana inoratidza kushanda kwayo kwakanaka mukuderedza mafambiro ecarbon, kuwedzera simba remakanika, uye kuwedzera hupenyu hwebasa rezvivakwa, zvichiita kuti ive chinhu chakakosha chinobatsira pazvinangwa zvekubvisa carbon dioxide pasi rose.

Zvidzidzo zvesainzi zvakaburitswa muna 2026 zvinosimbisa kuti metakaolin inovandudza zvikuru chimiro chekongiri, simba rekudzvanya, uye kugara kwenguva refu kwekongiri nedhaka. Painotsiva 12.5% ​​kusvika 15% yePortland cement, metakaolin blends inopa zvivakwa zvemukati zvakakora, elastic modulus yakakwira, uye inodzivirira kupinda kwechloride, sulfate attack, uye kukwegura kwekupisa kwakanyanya. Kuvandudzwa uku kunoita kuti metakaolin ive yakakodzera kune kongiri inoshanda zvakanyanya, tunnel grouting, zvivakwa zvegungwa, uye zvinhu zvakagadziriswa kare.

Kupfuura kuvaka, metakaolin iri kuwedzera mukugadzirisa zvakatipoteredza uye minda yekurapa. Ma microspheres e geopolymer akavakirwa paMetakaolin anoratidza kushanda zvakanaka mukusveta fluoride nesimbi dzinorema kubva mumvura ine acidic, zvichipa mhinduro yakaderera yekudzora kusvibiswa kwemaindasitiri. Panguva iyi, nano-hydroxyapatite/metakaolin composites itsva, dzinobva mumarara egoko rezai, dzinoratidza vimbiso yekushandisa scaffold yemapfupa, zvichibatanidza biocompatibility nekugadzikana kwemuchina.

Ruzivo rwemusika runoratidza kuti chikamu chepasi rose chemetakaolin chiri munzira yekukura kwakasimba, zvichikonzerwa nemitemo yekuvaka yakasarudzika uye mari yekudyara muzvivakwa. Musika wacho wakasvika pamadhora mabhiriyoni 1.3 muna 2024 uye unotarisirwa kudarika mabhiriyoni 2.2 emadhora panosvika 2033. Vagadziri vari kuwedzera nzira dzekugadzira kabhoni shoma vachishandisa kaolin tailings uye tembiricha yakaderera ye calcination (inenge 750°C), vachideredza kushandiswa kwesimba zvichienzaniswa nekugadzira simende yechinyakare.

Kushanda pamwe chete mumaindasitiri kuri kukurumidza kushandiswa. Makambani makuru ekugadzira zvinhu nemasangano ekutsvagisa ari kusimbisa metakaolin blends kuti ishandiswe pakugadzira zvinhu zvitsva, kugadzirisa migwagwa, uye kugadzira geopolymers dzisina marara. Mafekitori ekuedza ari kupihwa basa rekuvandudza kugadzirwa kwezvinhu zvitsva uye nzira dzekugovera zvinhu.

Sezvo indasitiri yekuvaka ichikurumidzisa kubvisa kabhoni mukugadzirwa kwezvinhu, metakaolin inoonekwa sechinhu chakabvumidzwa nehunyanzvi, chinoshanda zvakanaka mune zvemari, uye chinochengetedza nharaunda. Kuenderera mberi kweR&D kuchawedzera mukana wayo mukubatanidza zvinhu zvine kabhoni shoma, zvinhu zvekuvaka zvinodhindwa mu3D, uye masisitimu ehupfumi hwakatenderera, zvichigadzira nharaunda yakasimba uye ine hushamwari kune nharaunda pasi rese.
