Metakaolin, ibikoresho bya kaolin bifite calcium nyinshi, birimo kwiyongera ku isi nk'ibikoresho bihindura sima (SCM) n'inyongeramusaruro mu bwubatsi, ibidukikije, n'inganda zigezweho. Ubushakashatsi buherutse gukorwa n'igerageza ry'ubucuruzi bigaragaza imikorere yayo idasanzwe mu kugabanya imiterere ya karuboni, kongera imbaraga za mekanike, no kongera igihe cyo gukora ibikorwa remezo, biyishyira mu mwanya wayo nk'ikintu cy'ingenzi gifasha kugera ku ntego zo gukuraho karuboni ku isi.

Ubushakashatsi bwa siyansi bwasohotse mu 2026 bwemeza ko metakaolini irushaho kunoza imiterere mito, imbaraga zo gukanda, no kuramba kwa sima na sima. Iyo isimbuye sima ya Portland kuva kuri 12.5% ​​kugeza kuri 15%, imvange za metakaolini zitanga imiterere y'imbere ikomeye, modulus yoroshye cyane, kandi irwanya cyane kwinjira kwa chloride, igitero cya sulfate, no gusaza kw'ubushyuhe bwinshi. Izi ntambwe zituma metakaolini iba nziza cyane kuri sima ikora neza, imiyoboro y'amazi yo mu mazi, imiterere yo mu mazi, n'ibice byayo byateguwe mbere.

Uretse kubaka, metakaolin irimo kwaguka ikagera ku bikorwa byo gusana ibidukikije no mu rwego rw’ubuvuzi. Uduce duto twa geopolymer dushingiye kuri Metakaolin tugaragaza ubushobozi bwo gukura fluoride n’ibyuma biremereye mu mazi yanduye aside, bitanga igisubizo gihendutse cyo kurwanya umwanda mu nganda. Hagati aho, utwuma dushya twa nano-hydroxyapatite/metakaolin, dukomoka ku myanda y’ibishyimbo, tugaragaza icyizere cyo gukoresha mu gufunga amagufwa, tugahuza ubushobozi bwo guhuza ubuzima n’uburyo ibintu bihagaze.

Amakuru ku isoko agaragaza ko urwego rw’isi rwa metakaolini ruri mu nzira ihamye yo gukura, bitewe n’amategeko agenga inyubako zibungabunga ibidukikije n’ishoramari mu bikorwa remezo. Isoko ryageze kuri miliyari 1.3 z’amadolari y’Amerika mu 2024 kandi biteganijwe ko rizarenga miliyari 2.2 z’amadolari y’Amerika mu 2033. Abakora ibicuruzwa barimo kongera inzira zo gukora karuboni nke bakoresheje imirasire ya kaolini no kugabanya ubushyuhe bwa calcination (hafi dogere selisiyusi 750), bagabanya ikoreshwa ry’ingufu ugereranije n’inganda zisanzwe zikora sima.

Ubufatanye mu nganda buri kwihutisha ikoreshwa. Ibigo bikomeye by’ibikoresho n’ibigo by’ubushakashatsi birimo kwemeza imvange za metakaolini mu rwego rwo gushushanya, kubungabunga imihanda, no gukoresha geopolymers zitangiza imyanda. Inganda z’igerageza ziri gutangwa kugira ngo zinoze uburyo umusaruro uhoraho n’uruhererekane rw’ibicuruzwa.

Mu gihe inganda z’ubwubatsi zihutisha ikoreshwa rya karuboni, metakaolini igaragara nk’ibikoresho byemejwe mu rwego rwa tekiniki, bifite akamaro mu bukungu, kandi bibungabunga ibidukikije. Ubushakashatsi n’iterambere buzarushaho gufungura ubushobozi bwabyo mu bikoresho bifunga karuboni nke, ibikoresho by’ubwubatsi bishobora gucapwa mu buryo bwa 3D, hamwe n’inganda zikora ubukungu buzunguruka, bitume ibidukikije byubatswe ku isi yose bikomera kandi bitangiza ibidukikije.
