Ibikoresho bihindura umwuka bikoreshwa mu itanura rizunguruka ry’imyanda ihumanya ikirere bishyirwamo calcium hamwe n’ibice bigoye kandi bidahindagurika. Intego yo gutwika imyanda ihumanya ikirere ni ugutwika imyanda ihumanya ikirere ikayihinduramo icyuma no kugabanya ubushyuhe bw’ibisigazwa kugeza munsi ya 5%. Iyo nta gisenge kiri mu itanura, uburyo bwo guhitamo imyanda ihumanya ikirere mu itanura rizunguruka ry’imyanda ihumanya ikirere butandukanye rwose n’ubwo mu itanura rizunguruka.
Ku bikoresho birwanya imyuka ikoreshwa mu itanura rizunguruka mu gutunganya imyanda ihumanya, imiterere y’imyanda ihumanya ni ingenzi bitewe n’ubwoko bwayo butandukanye, bityo byemezwa ko imiterere y’imyanda ihumanya itwikwa ku bushyuhe bwa 700-1000 mu itanura rizunguruka, kandi imiterere nyamukuru y’imyuka irekurwa nyuma yo gukaraba imyanda ihumanya ni aside nkeya.
Mu itanura rihindagurika, rishobora gushonga ku mwuka ushyushye rikagira ubuziranenge bwiza, itanura rizunguruka rya AL2O3 SiO2 ni irihangana neza n’ubushyuhe kandi rishobora gushonga, iyo uhisemo ibikoresho birwanya ubushyuhe, ntabwo ari uguhitamo ibikoresho birwanya ubushyuhe, ingano ya Fe2O3 ishoboka bitewe na Fe2O3 FeCL3 ihura na gazi ya chlorine, imiterere ya gazi ihinduka, ihinduka kandi irenze urugero mu matafari arwanya ubushyuhe, itanura rizunguruka rya sima rikunze gukoreshwa mu kurwanya ubushyuhe bw’umusaruro wo kurinda ibidukikije. Amatafari ya Magnesia icyuma cy’umugongo, mu itanura rizunguruka ry’imyanda ihindagurika ntabwo bikwiye, mu itanura rizunguruka ry’imyanda ihindagurika n’aho isohoka, hagomba kandi gutoranywamo sima nto ihindagurika, kuko CaO na chlorine, ikorwa rya CaC1 y’amazi bizagabanya ubushyuhe n’ubushyuhe bwinshi bw’itara.
Mu guhitamo ibikoresho birwanya ikwirakwira ry’umuriro, itanura rizunguruka ry’imyanda iteje akaga rigomba gukoresha ibikoresho birwanya ikwirakwira ry’umuriro, ridashobora kwangirika cyane, ridashobora gushyuha cyane kandi ridashobora kwangirika. Uburyo bwo gukora itanura rizunguruka ry’imyanda iteje akaga muri rusange bukoresha inzira yo gutwika. Imyanda iteje akaga ituruka mu kirere ituruka mu cyerekezo kimwe kandi uburebure bw’itanura ni bugufi (ikigereranyo cy’uburebure n’umurambararo muri rusange ni metero 3-5 gusa). Uburyo iri mu itanura rikora ni bworoshye, ni ukuvuga uburyo bwo gutwika. Mu bicuruzwa bisanzwe bikoreshwa ubu, amatafari ya mullite ni yo akwiriye cyane, kandi ibikoresho bishobora gutwikwa bishobora gutorwamo mullite.
