Ka ntlafatso ea boemo ba morao-rao ba kaho, mohaho oa mohaho o fetoha o rarahaneng haholoanyane, tlhokahalo ea konkreite e ntse e hōla, 'me litlhoko tsa ts'ebetso ea konkreite le tsona li ntse li phahama. Tlatsetso e sebelisetsoa ho ntlafatsa ts'ebetso ea konkreite. Ka hona, palo ea li-additives tse hlokahalang le eona e ntse e eketseha, 'me litlhoko li ntse li eketseha. Ka hona, li-admixtures tsa konkreite tsa nakong e tlang li tla ntlafatsoa ka likarolo tse latelang. Moemeli oa ho fokotsa metsi ho loha hanyane ho nka hore u hlahlobe.
(1) Mofuta o kopaneng. Li-compound admixtures li ka etsa bofokoli bo sebetsang hantle 'me li tsoela pele ho ntlafatsa, ka theko e tlase, mefuta e mengata ea ts'ebeliso le litšobotsi tse ntle haholo.
(2) Likarolo ke tsa bokahohleng ebile li fapane. E le hore re tsoele pele ho hlahisa lihlahisoa tse ncha tse nang le mefuta e metle ka ho fetisisa le ho etsa hore mefuta e fapaneng e be ea bokahohle le ea mefuta-futa, re lokela ho qala ka ho nahana ka litlhoko tsa mefuta e sa tšoaneng ea merero ea boenjiniere, le ho tsamaisa ts'ebeliso ea merero ea boenjiniere le tsamaiso ea boleng.
(3) Hlahisa li-additives tse matla haholo. Lilemong tsa morao tjena, matla a tloaelehileng a khatello le matla a holimo a ho hatella a konkreite e sebelisoang hangata a tla tsoela pele ho ntlafala, 'me nts'etsopele ea matla a phahameng, admixture e phahameng ea katleho bakeng sa ho hanyetsa botsofali e tla hlokahala. Bakeng sa ho hlahisa matla a phahameng le konkreite e matla ka ho fetesisa, tšebeliso ea matla a ho fokotsa metsi ka mokhoa o phahameng oa ho fokotsa metsi o tla hlahisa konkreite e kholo ea phallo, e tla boloka boiteko ba kaho, ho fokotsa litšenyehelo tsa morero, le ho ntlafatsa katleho ea basebetsi.
(4) Fokotsa litšenyehelo tsa li-additives. Tšebeliso e feto-fetohang ea litšila tse fapaneng tsa tlhahiso ea indasteri ho hlahisa li-additives, ho fetola le ho nchafatsa mokhoa oa ho hlophisa le mokhoa oa tlhahiso ea li-additives. Hlahisa le ho etsa mefuta ea motsoako ka theko e tlase, boleng bo holimo le ts'ebetso e phahameng, e le ho ntlafatsa tlholisano ea 'maraka bakeng sa ts'ebeliso e pharalletseng le ho khothaletsa motsoako oa konkreite.
(5) Ntlafatsa, tlhahlobo e tebileng ea molao-motheo oa katleho ea li-concrete admixtures. Ka nts'etsopele ea tsoelo-pele ea mahlale le mahlale a mahlale, mekhoa e metle ea tlhahlobo e lokela ho khethoa, 'me molao-motheo oa ts'ebetso ea li-additives o lokela ho etsoa lipatlisiso le ho nts'etsopele ho theha motheo oa ho tebisa le ho fana ka papali e felletseng ea katleho ea li-additives, ho fumana melemo e matla ea moruo, le ka nepo. ho tataisa tlhahiso le tlhahiso.
Ka kakaretso, ke mokhoa o sebetsang oa ho khothaletsa lipatlisiso tsa mahlale le nts'etsopele ea indasteri ea kaho ho nts'etsapele le ho sebelisa li-additives tsa konkreite. Ka nts'etsopele e tsoelang pele, moralo le ntlafatso ea li-admixtures tsa konkreite, boleng bo tla ntlafatsoa haholo, ts'ebeliso e tla ata haholo, 'me ts'ebetso e tla tsoela pele ho ntlafala, e leng se tla tlisa melemo e mengata ea moruo indastering ea kaho. Boemo ba mohaho le bona bo tla nyolohela boemong bo phahameng.
