1. Lisebelisoa tsa Cementitious: Thepa ea samente ea seretse se ikemetseng sa gypsum ke gypsum ea boleng bo holimo.Lisebelisoa tse tala bakeng sa ho hlahisa gypsum ea moaho ke haholo-holo gypsum ea tlhaho e nang le calcium sulfate kapa gypsum ea lihlahisoa tsa indasteri ka mor'a ho phekoloa pele le ho hloekisa, 'me phofo ea gypsum ea moaho e finyellang maemo a naha e fumanoa ka calcining ka mocheso o utloahalang oa tshebetso.
2. Li-admixtures tse sebetsang: Fly molora, phofo ea slag, joalo-joalo e ka sebelisoa e le li-admixtures tse sebetsang bakeng sa thepa ea boipheliso.Sepheo ke ho ntlafatsa phallo ea likaroloana tsa thepa le ho ntlafatsa ts'ebetso ea thepa e thata.Motsoako o sebetsang le lisebelisoa tsa cementitious li ka ntlafatsa compactness le matla a morao-rao a sebopeho sa thepa ka karabelo ea hydration.
3.

4. Moemeli oa ho fokotsa metsi: E le ho ntlafatsa compactness le matla a thepa ea ho ikemela, hoa hlokahala ho fokotsa tekanyo ea metsi-binder.Tlas'a boemo ba ho boloka metsi a matle a lisebelisoa tsa ho ikemela, hoa hlokahala ho eketsa lisebelisoa tse fokotsang metsi.Lisebelisoa tse fokotsang metsi tse lumellanang le li-gypsum tse fapaneng tsa moaho li ka sebelisoa ho etsa hore ho thella lipakeng tsa likaroloana tsa thepa ho be bonolo, ka hona ho fokotsa bongata ba metsi a kopanyang a hlokahalang le ho ntlafatsa sebopeho sa thepa e thata.
5. Setsi sa ho boloka metsi: Lisebelisoa tsa ho ikemela li hahiloe fatše, 'me botenya ba kaho bo batla bo le mosesaane,' me metsi a kenngoa habonolo ke motheo oa fatše, e leng se bakang ho se be le metsi a lekaneng a lisebelisoa, mapetsong holim'a metsi, matla a fokotsehileng.Ka kakaretso, viscosity e tlase (tlase ho 1000)cellulose ether (HPMC)se sebedisoang joalo ka sekoaelo sa metsi.Cellulose ether e na le mongobo o motle, ho boloka metsi le thepa ea ho etsa filimi, e le hore thepa ea boipheliso e se ke ea tsoa mali 'me e na le metsi a feletseng.
6. Moemeli oa ho senya: Moemeli oa defoaming a ka ntlafatsa ts'ebetso e bonahalang ea thepa ea boipheliso, a fokotsa li-bubble tsa moea ha thepa e thehoa, 'me a ba le phello e itseng ho ntlafatsa matla a thepa.
