Simenti yayikulu ya aluminiyamu imapangidwa pophatikiza zopangira zosankhidwa mu ng'anjo yapadera. Pambuyo pozizira, clinker imadulidwa pogwiritsa ntchito mphero za mpira. Zopangira za simenti yapamwamba ya alumina refractory CA-70 ndi zida za calcium zoyera komanso aluminiyamu yoyera kwambiri. Zopangira ziyenera kusakanizidwa molingana ndi chiŵerengero choyenera. Zopangira ziyenera kutenthedwa kuti zisakanike pang'ono. Zomwe zili mu Al2O3 nthawi zambiri zimayendetsedwa mkati mwa 68% mpaka 72%. Zosakaniza zake zazikulu ndi CA ndi CA2.
1.Kuchita bwino pakugwedezeka kwamafuta, dzimbiri, kukokoloka ndi kukana abrasion,
2. High refractoriness ndi mphamvu kwambiri makina,
3.Zomwe zimagwirira ntchito pafupipafupi komanso mosalekeza ndizovomerezeka, kuchepetsa ming'alu ya mizere,
4.Kuzungulira kwanthawi yayitali komanso kosasunthika kuti mukwaniritse bwino kwambiri,
5.Suit kwa mitundu yonse yazitsulo, kuchepetsa zotsalira ndi porosity ya mankhwala,
6.Labor ndi kupulumutsa mtengo mwa kukhazikitsa ndi kukonza bwino.

Simenti yapamwamba ya alumina imagwiritsidwa ntchito makamaka pazosowa zapadera zomanga mwadzidzidzi, kukonza mwadzidzidzi, kukana sulfate ndi kumanga kwachisanu. Ndipo simenti yapamwamba ya alumina refractory imagwiritsidwa ntchito makamaka pamadongosolo achangu, monga chitetezo champhamvu, misewu ndi ma projekiti apadera okonza. Komanso simenti yoyaka moto ya aluminiyamu imagwiritsidwa ntchito pamalo otsatirawa:
RS refractory fakitale ndi katswiri wopereka simenti wa alumina refractory yemwe adakhazikitsidwa koyambirira kwa 90s zaka makumi awiri. Fakitale ya RS refractory yakhazikika pa simenti yayikulu ya alumina kwa zaka zopitilira 20. ngati mukufuna simenti yapamwamba ya alumina, kapena muli ndi mafunso pa zircon mulite refractory bricabout zosonyeza thupi ndi mankhwala, chonde titumizireni kwaulere. ndi Rs refractory fakitale monga katswiri wopanga njerwa za zircon mulite refractory ku China, ali ndi mwayi wampikisano motere:
