Puisano ka Lintlha tse Amang Mokelikeli oa Seretse

Mokelikeli oa seretse, oo hangata o bitsoang ho sebetsa ha oona kapa ho tsitsisa ha oona, ke thepa ea bohlokoa e amang likarolo tse fapaneng tsa kaho, ho kenyeletsoa ho beoa habonolo, ho tiisa le ho qeta. Lintlha tse 'maloa li susumetsa ho phalla ha seretse,' me ho utloisisa lintlha tsena ho bohlokoa bakeng sa ho finyella ts'ebetso e nepahetseng mererong ea kaho. Mona ke puisano ka lintlha tse ling tsa bohlokoa tse amang metsi a seretse:

1. Metsi-to-Binder Ratio: Karo-karolelano ea metsi-to-binder, e emelang karo-karolelano ea metsi ho thepa ea samente (samente, lime, kapa motsoako), e ama haholo metsi a seretse. Ho eketsa metsi ho ka ntlafatsa ts'ebetso ka ho fokotsa viscosity le ho eketsa phallo. Leha ho le joalo, metsi a feteletseng a ka etsa hore ho be le khethollo, ho tsoa mali le ho fokotsa matla, kahoo ke habohlokoa ho boloka tekanyo e nepahetseng ea metsi ho ea ho e kopanyang bakeng sa metsi a lakatsehang ntle le ho senya ts'ebetso ea seretse.
2. Mofuta le Karohano ea Li-aggregates: Mofuta, boholo, sebopeho, le ho aroloa ha likarolo tse sebelisoang ka seretse li ama thepa ea eona ea rheological le mokelikeli. Li-aggregate tse ntle, tse kang lehlabathe, li ntlafatsa ts'ebetso ka ho tlatsa li-voids le likaroloana tsa lubricating, ha lihlopha tse mahoashe li fana ka botsitso le matla. Li-aggregates tse hlophisitsoeng hantle tse nang le kabo e leka-lekaneng ea boholo ba likaroloana li ka matlafatsa ho phutheha ha seretse le ho phalla ha seretse, ho fella ka ho ntlafala ha metsi le momahano.
3. Phatlalatso ea Size ea Particle: Kabo ea boholo ba likaroloana tsa thepa ea samente le likaroloana li susumetsa boima ba ho paka, ho ferekana ha likaroloana, le ho phalla ha seretse. Likaroloana tse ntle li ka tlatsa likheo lipakeng tsa likaroloana tse kholo, tsa fokotsa ho hanyetsana le ho ntlafatsa phallo. Ka lehlakoreng le leng, phapang e pharaletseng ea boholo ba likaroloana e ka lebisa karohano ea likaroloana, ho fokola ho fokolang, le ho fokotseha ha metsi.
4. Metsoako ea Lik'hemik'hale: Metsoako ea lik'hemik'hale, joalo ka li-reductions tsa metsi, li-plasticizers le li-superplasticizers, li ka ama haholo ho phalla ha seretse ka ho fetola sebopeho sa eona sa rheological. Lisebelisoa tsa metsi li fokotsa metsi a hlokahalang bakeng sa ho theoha ho fanoeng, ho matlafatsa ts'ebetso ntle le ho senya matla. Li-plasticizers li ntlafatsa momahano le ho fokotsa viscosity, ha li-superplasticizers li fana ka phallo e phahameng le thepa ea ho ikemela, haholo-holo ka har'a liretse tse iketsetsang.
5. Mofuta oa Binder le Sebopeho: Mofuta le sebopeho sa li-binder, tse kang samente, lime, kapa metsoako ea eona, li susumetsa hydration kinetics, nako ea ho beha, le boitšoaro ba rheological ba seretse. Mefuta e fapaneng ea samente (mohlala, samente ea Portland, samente e kopantsoeng) le lisebelisoa tsa tlatsetso tsa cementitious (mohlala, molora o fofang, slag, silika fume) li ka ama metsi le ho tsitsa ha seretse ka lebaka la ho fapana ha boholo ba likaroloana, reactivity, le litšobotsi tsa hydration.
6. Mokhoa oa ho Kopanya le Lisebelisoa: Mokhoa oa ho kopanya le lisebelisoa tse sebelisoang ho lokisa seretse li ka ama metsi a eona le homogeneity. Mekhoa e nepahetseng ea ho kopanya, ho kenyelletsa nako e loketseng ea ho kopanya, lebelo, le tatellano ea ho eketsoa ha lisebelisoa, ke tsa bohlokoa bakeng sa ho finyella ho qhalakanngoa ha metsoako le thepa e tsitsitseng ea rheological. Ho kopanya ho fosahetseng ho ka etsa hore ho be le hydration e lekaneng, karohano ea likaroloana, le kabo e sa tšoaneng ea li-admixtures, e amang ho phalla le ho sebetsa ha seretse.
7. Maemo a Tikoloho: Maemo a tikoloho a kang mocheso, mongobo le lebelo la moea li ka susumetsa ho phalla ha seretse nakong ea ho kopanya, ho tsamaisa le ho behoa. Lithempereichara tse phahameng li potlakisa hydration le ho beha, ho fokotsa ts'ebetso le ho eketsa kotsi ea ho phunyeha ha polasetiki. Lithempereichara tse tlase li ka sitisa maemo le ho fokotsa mokelikeli, ho hloka hore ho lokisoe litekanyo le litekanyo tsa motsoako ho boloka ts'ebetso e lakatsehang.

mokelikeli oa seretse o susumetsoa ke motsoako oa lintlha tse amanang le thepa, moralo oa motsoako, mekhoa ea ho kopanya, le maemo a tikoloho. Ka ho shebisisa lintlha tsena ka hloko le ho ntlafatsa likarolo tsa motsoako, litsebi tsa kaho li ka fihlela seretse ka mokelikeli o lakatsehang, botsitso le ts'ebetso bakeng sa lits'ebetso tse ikhethileng le litlhoko tsa projeke.
