I-alkali proof castable ine-liquidity ephezulu futhi ifanele izinto eziphikisayo ezingabunjiwe ezenziwe ngohlobo lokuthululwa. I-alkali proof refractory castable inezici ezihlukahlukene zokumelana nokushisa okuphezulu, amandla aphezulu emishini kanye nokumelana nokuguguleka kwe-asidi eqinile yazo zonke izinhlobo zeziko nokufakwa kweziko. I-alkali proof castable ingasabela nge-metal oxide ezingeni lokushisa eliphezulu ikhiqize imikhiqizo yoketshezi ephezulu ye-viscosity, eyenza ungqimba olucwebezelayo lugweme ukungena nokuguguleka kwensimbi encibilikayo ye-alkali.
I-alkali proof refractory castable yenziwe ngama-refractory aggregates, ama-binders kanye ne-alkali resistance powder. Izingxenye zayo ziyi-ceramsite, i-clinker yenhlabathi enamathelayo, imfucumfucu ye-porcelain, i-perlite enamandla amakhulu, njll. kanye nosimende we-calcium aluminate kanye ne-sodium silicate njengezibophezelo.
Ngokwezimo nezindawo ezihlukene, i-alkali proof castable ingahlukaniswa ibe ukukhanya kwe-alkali proof castable kanye ne-alkali proof castable. Lawo ane-porosity engaphezu kuka-45% anobufakazi be-alkali elula futhi lawo ane-porosity engaphansi kuka-45% anobufakazi obuqinile be-alkali obungalahleka. Ikhwalithi esindayo ye-alkali proof castable ingahlukaniswa ibe yizinga lokushisa eliphakathi nendawo elifaka ubufakazi be-alkali futhi izinga lokushisa eliphakeme le-alkali proof castable.

I-refractory alkali proof castable isetshenziswa kakhulu eziko ezimbonini eziguguleka ngezinto ze-alkali, njenge-kiln hood, isistimu ye-preheater, isithando somlilo sokubola. Futhi ingasetshenziswa endaweni elandelayo.
Ifekthri ye-RS refractory iwumphakeli ochwepheshile ofaka ubufakazi be-alkali owasungulwa ekuqaleni kwawo-90s wekhulunyaka elingamashumi amabili. Ifekthri ye-RS refractory ikhethekile kuma-castable obufakazi be-alkali iminyaka engaphezu kwengu-20. uma unesidingo esithile sobufakazi be-alkali ephikisayo, noma unemibuzo ngobufakazi be-alkali ephikisayo obungafakakala mayelana nezinkomba ezibonakalayo namakhemikhali, sicela usithinte mahhala. kanye nefekthri ye-Rs refractory njengomkhiqizi we-alkali proof castable castable e-china, inezinzuzo ezithile zokuncintisana ngale ndlela elandelayo:
