Iyini i-Admixture in Construction?

Ekwakhiweni, ingxube isho enye into ngaphandle kwamanzi, izilinganiso, izinto zikasimende, noma imicu engezwa kukhonkolo, udaka, noma i-grout ukuze kuguqulwe izakhiwo zayo noma ukuthuthukisa ukusebenza kwayo. Ama-Admixtures asetshenziselwa ukuguqula ukhonkolo omusha noma oqinile ngezindlela ezihlukahlukene, okuvumela ukulawula okukhulu phezu kwezakhiwo zawo futhi kuthuthukise ukusebenza kwawo, ukuqina, amandla, nezinye izici. Nazi ezinye izinhlobo ezivamile zezingxube ezisetshenziswa ekwakheni:

1. Ingxube Eyehlisa Amanzi:

• Izixube ezinciphisa amanzi, ezaziwa nangokuthi ama-plasticizers noma ama-superplasticizers, ziyizithasiselo ezinciphisa okuqukethwe kwamanzi okudingekayo ukuze kuzuzwe ukusebenza okufunayo kokhonkolo ngaphandle kokudela amandla noma ukuqina. Bathuthukisa ukugeleza nokusebenza kwezingxube zikakhonkolo, okwenza kube lula ukuzibeka nokuqeda.

2. Izixube ezihlehliswayo:

• Izixube zokuhlehlisa zisetshenziselwa ukubambezela isikhathi sokusetha sikakhonkolo, udaka, noma i-grout, okuvumela ukusebenza okunwetshiwe nesikhathi sokubeka. Ziwusizo ikakhulukazi esimweni sezulu esishisayo noma kumaphrojekthi amakhulu lapho ukubambezeleka kwezokuthutha, ukubekwa, noma ukuqedwa kulindeleke.

3. Ukusheshisa Okuxubile:

• Izixube ezisheshayo ziyizithasiselo ezisheshisa ukulungiselelwa kanye nokuthuthukiswa kwamandla okuqala kakhonkolo, udaka, noma i-grout, okuvumela inqubekelaphambili yokwakha esheshayo kanye nokususwa kwangaphambi kwesikhathi kwe-formwork. Zivame ukusetshenziswa ezimweni zezulu ezibandayo noma lapho kudingeka ukuzuza amandla ngokushesha.

4. I-Air-Entraining Admixtures:

• Izingxube ezifaka umoya ziyizithasiselo ezethula amabhamuza omoya amancane abe ukhonkolo noma udaka, okuthuthukisa ukumelana kwawo nemijikelezo yokuncibilika, ukukala, nokuhuzuka. Bathuthukisa ukusebenza nokuqina kukakhonkolo ezimweni zezulu ezinzima futhi banciphisa ingozi yokulimala ngenxa yokuguquguquka kwezinga lokushisa.

5. Ukunciphisa Ukuhlanganiswa Kwe-Air-Entraining:

• Ingxubevange yokungenisa umoya ehlehlisayo ihlanganisa izici zokuhlehlisa kanye nezixube zokungenisa umoya, ibambezela isikhathi sokumisa sikakhonkolo ngenkathi iphinde ifaka umoya ukuze uthuthukise ukumelana kwawo nokuncibilika. Avame ukusetshenziswa ezindaweni ezibandayo noma ukhonkolo ovezwe emijikelezweni yokuqandisa nokuncibilika.

6. Izingxube Ezivimbela Ukugqwala:

• Izingxube ezivimbela ukugqwala ziyizithasiselo ezisiza ukuvikela ukuqiniswa kwensimbi okugxilile kukhonkolo ekugqwaleni okubangelwa ukuchayeka kumswakama, ama-chloride, noma ezinye izinto ezinolaka. Bandisa impilo yesevisi yezakhiwo zikakhonkolo futhi banciphise izindleko zokulungisa nokulungisa.

7. Inhlanganisela Enciphisa Ukuncipha:

• Izingxube ezinciphisa ukushwabana ziyizithasiselo ezinciphisa ukomisa ukuncipha kukhonkolo, udaka, noma igrout, okunciphisa ubungozi bokuqhekeka nokuthuthukisa ukuqina kwesikhathi eside. Ziwusizo ikakhulukazi ezindaweni ezinkulu ezibekwayo zikakhonkolo, izakhi zikakhonkolo ezifakwe ngaphambili, nezingxube zikakhonkolo ezisebenza kahle kakhulu.

8. Izixube Zokuvimbela Amanzi:

• Izithako zokuvikela amanzi ziyizithasiselo ezithuthukisa ukungagxili kukakhonkolo, udaka, noma i-grout, enciphisa ukungena kwamanzi futhi ivimbele izindaba eziphathelene nomswakama ezifana ne-efflorescence, umswakama, nokugqwala. Avame ukusetshenziswa ezakhiweni ezingaphansi kwebanga, amagumbi angaphansi, imigudu, nezakhiwo ezigcina amanzi.

Kafushane, izingxube zidlala indima ebalulekile kubuchwepheshe besimanje obuphathekayo, okuvumela ukuguquguquka okukhulu, ukusebenza kahle, nokusebenza kumaphrojekthi wokwakha. Ngokukhetha kanye nokuhlanganisa izixube ezifanele kuzingxube zikakhonkolo, abakhi nonjiniyela bangafinyelela izimfuneko ezithile zedizayini, bathuthukise izinqubo zokwakha, futhi bathuthukise ukuqina nokusimama kwezakhiwo zikakhonkolo.
