Tšebelisano lipakeng tsa metsoako le samente:

Mosebetsi o ka sehloohong oa li-admixtures ke ho ntlafatsa ts'ebetso ea konkreite ka ho eketsa metsoako e lumellanang le konkreite, ka hona ho khothalletsa ntlafatso ea boleng ba kaho le katleho ea merero ea kaho. Lebaka leo ka lona li-admixtures li ka khothalletsang ntlafatso ea thepa e fapaneng ea konkreite ke hore li ka hlahisa liphello tse tšoanang ka konkreite. Hangata, litlamorao lipakeng tsa li-admixtures le konkreite lia fetoha, li tsamaellana ebile lia lumellana. Kaha likarolo tsa mantlha le boholo ba likarolo tse fapaneng tsa li-admixtures li fapane haholo, ho ikamahanya le maemo lipakeng tsa li-admixtures tse fapaneng le konkreite le tsona li tla fapana haholo. Li-admixtures tse nang le maemo a fokolang a fokolang li ka 'na tsa se ke tsa baka feela sekhahla sa ho fokotsa metsi a konkreite, empa hape se etsa hore konkreite e behe ka potlako haholo, kahoo e ama mohaho o tloaelehileng oa morero. Li-admixtures tse nang le maemo a matle li ka ntlafatsa ka nepo sekhahla sa phokotso ea metsi ea konkreite le ho qoba ho phatloha le ho phatloha ha konkreite ho isa bohōleng bo itseng. Ho bapisa li-admixtures le konkreite ho tla ama katleho ea adsorption ea konkreite ho li-admixtures. Haeba ho bapisoa ha li-admixtures le konkreite ho le tlase, katleho ea adsorption ea konkreite ho li-admixtures e tla ba tlase haholo, e tla ama litlamorao tse fapaneng tsa li-admixtures tsa eona. Ho lumellana ha li-admixtures le konkreite ho tla ama katleho ea tšebeliso ea li-admixtures. Haeba ho lumellana ha li-admixtures le konkreite ho fokola, konkreite e ke ke ea khona ho kopana le li-admixtures, tse tla lebisa ho senyeha ha metsoako e meng.

Litlhahiso mabapi le melao-motheo ea khetho ea li-premixed concrete admixtures:

1. Baetsi ba motsoako oa konkreite ba hloka ho ba le lits'ebeletso tse phethahetseng tsa pele ho thekiso le kamora ho rekisa. Ha ho rekisoa metsoako ea konkreite, baetsi ba metsoako ea konkreite ba lokela ho tsepamisa maikutlo linthong tse amehang, ho theha litokomane tsa botekgeniki tse batlang li feletse ka hohle kamoo ho ka khonehang, ho fana ka litaelo tsa motsoako oa konkreite, 'me ba netefatse hore thekiso ea li-admixtures tsa konkreite e etsoa ka har'a sebaka sa tšehetso ea tekheniki e fumanehang.

2. Khetha boleng bo nepahetseng ba motsoako. Ha u khetha li-admixtures tsa konkreite tse kentsoeng pele, hoa hlokahala ho tseba ka botlalo mefuta e fapaneng e sebetsang le litekanyetso tsa li-admixtures. Fumana li-admixtures tsa konkreite tse loketseng litekong tsa ho bapisa, khetha li-admixtures tsa boleng bo holimo ka hohle kamoo ho ka khonehang, 'me u fane ka papali e felletseng ea karolo ea li-admixtures tsa konkreite.

3. Khetha leano la metering le loketseng tlhahiso ea boiketsetso. Ho khetha leano la metering le loketseng bakeng sa boiketsetso ba tlhahiso le eona ke e 'ngoe ea melao-motheo ea bohlokoa bakeng sa khetho ea li-admixtures tsa konkreite tse kopaneng.

4. Ho khetha metsoako e nang le melemo e phahameng ea moruo Ho khethoa ha metsoako e nang le melemo e phahameng ke ho finyella litlhoko tsa kaho le tlhahiso ea lihlopha tsa kaho. E lokela ho lumellana le boemo ba hajoale ba likarolo tsa kaho, e be le litšobotsi tse itseng tsa tlhahlobo e felletseng, e fihlelle litlhoko tsa index ea moruo ea likarolo tsa kaho ho isa bohōleng bo itseng, 'me e be le litšobotsi tsa melemo ea moruo. Ka hona, morero ona oa khetho ea motsoako o lemohuoa ka botebo ke likarolo tsa kaho.
