Uruganda Igiciro Cyiza KalisiyumuAlumina Cement CAS: 65997-16-2
KalisiyumuAlumina Cement ni sima hamwe na calcium calcium cyangwa calcium aluminium nkibigize imyunyu ngugu.Ikozwe muri aluminiyumu karemano cyangwa alumina yinganda na calcium karubone (limestone) ukurikije igipimo runaka, ikorwa no gutwika cyangwa gushonga amashanyarazi.
Ibigize hamwe nibyiciro: KalisiyumuAlumina Cement irashobora kugabanywamo calcium ya calcium ya calcium isanzwe ya aluminium (al2O3 53-72%, CAO 21-35%) hamwe na sima ya aluminiyumu yuzuye (al2O3 72-82%, CAO 19-23%) Ibyiciro bibiri.Isima isanzwe ya sima ya sima irashobora kugabanywa mubwoko buke -iron (FE2O3 <2%) n'ubwoko bwa gari ya moshi yihuta (Fe2O37-16%).Ubutaka -ubwoko bwa aluminium -ubwoko bwa calcium ya sima irashobora kugabanywa mubutaka bwa alum sima (Al2O353 ~ 56%, CAO 33-35%), sima ya aluminium -60 (al2O359% kugeza 61%, CAO 27-31%), na hasi -isima ya aluminiyumu ya sima (Al2O3 65-70%, CAO 21 kugeza 24%).Isima ya calcium ya aluminiyumu irashobora kugabanywamo ubwoko bubiri: Al2O3 72-78%) nubwoko bwa ultra -high aluminium (Al2O3 78-85%).Mubyongeyeho, hariho byihuse kandi bikomeye hakiri kare aluminium calcium ciment.CAS: 65997-16-2
