Mefuta e mengata ea li-castable e ka aroloa e le li-castable tse bobebe, ho itšetlehile ka sebopeho sa tsona le thepa e khethehileng. Mehlala e meng e tloaelehileng e kenyelletsa:
1.Insulating castables : Li-castable tsena li etselitsoe haholo-holo bakeng sa thepa ea tsona e ntle ea ho itšireletsa. Li na le boima bo tlase ba bongata le porosity e phahameng, e fihlelletsoeng ka ho kenyelletsa likarolo tse bobebe tse kang perlite e atolositsoeng, vermiculite, kapa likhoele tse bobebe tsa refractory.
2.Li-castable tse tlase-tlase : Li-castable tsena li entsoe hore li be le letsoalo le tlase ha li ntse li fana ka matla a lekaneng a mochini. Hangata li na le li-aggregates tse bobebe joalo kacenospheres , chamotte e bobebe, kapa mullite e bobebe. Motsoako oa lisebelisoa tsena tse bobebe le li-agent tsa bonding li fella ka li-castable tse nang le boima bo fokotsehileng.
3.Foam castables : Li-foam castables li entsoe ka ho kenyelletsa moemeli o hlahisang foam ka har'a motsoako o ka lahlehang, o etsang hore ho be le sebopeho sa lisele tsa cellular ha ho omisoa le ho thunya. Sebopeho sena sa cellular se kenya letsoho ho fokotseng sekhahla le ho ntlafatsa thepa ea ho kenya letsoho. Lisebelisoa tsa foam hangata li na le li-aggregate tse bobebe le li-agent tse foaming.
4.Litholoana tsa vermiculite : Vermiculite ke diminerale ea tlhaho e atolohang ha e futhumala. Li-castable tsa vermiculite li kenyelletsa li-aggregate tse atolositsoeng tsa vermiculite, tse kenyang letsoho ho fokotseng sekhahla le thepa e ntle ea ho kenya letsoho. Li-castable tsena li loketse lisebelisoa tsa mocheso o itekanetseng.
5.Lisebelisoa tsa alumina tse nang le li-bubble : Bubble alumina ke ntho e bobebe, e nang le porous aggregate e hlahisoang ka ho futhumatsa sehlopha se khethehileng sa alumina ho mocheso o phahameng, e leng se hlahisang li-bubble tsa khase ka har'a thepa. Li-bubble alumina castables li bobebe ebile li na le thepa e ntle ea ho itšireletsa, e li etsang hore li tšoanelehe bakeng sa lits'ebetso tsa mocheso o phahameng.
Ho bohlokoa ho hlokomela hore sebopeho le likarolo tse ikhethileng tsa li-castable tse bobebe li ka fapana ho bahlahisi mme li ka etselitsoe lits'ebetso tse ikhethileng. Ka hona, kamehla ho khothaletsoa ho buisana le barekisi kapa bahlahisi ba refractory ho fumana hore na ke mofuta ofe o loketseng oa ho lahlela morero o itseng kapa sesebelisoa se itseng.
