Izinhlobo ezijwayelekile zokuxutshwa nendima yazo kukhonkolo osulungile:

Ama-concrete admixtures ayingxenye ebalulekile yokuthuthukisa ukusebenza kwekhonkrithi, futhi izinhlobo ezihlukahlukene ze-admixtures zinezindima ezihlukene ekukhoneni okuxubile okulungiselelwe. Izinhlobo ezivame kakhulu zokuxutshwa yizinciphisi zamanzi, ama-accelerator, ama-antifreeze agents kanye nama-preservatives. Njengengxenye eyinhloko kukhonkolo, izinciphisi zamanzi zinganciphisa kakhulu inani lamanzi asetshenziswa kukhonkolo futhi zithuthukise ukusebenza namandla okukhonkolo. Ukusetshenziswa kwezinciphisi zamanzi kungenza ukhonkolo ube lula ukwakha, uketshezi olungcono, futhi kukhuthaze ukuhlakazwa okungcono kwezinhlayiya zikasimende, ngaleyo ndlela kuthuthukiswe amandla okuqala kanye nokunqanda ukungena kukakhonkolo.

Ama-Accelerator angakhuthaza ukuqina okusheshayo kokhonkolo futhi afinyeze isikhathi sokuqala sokusetha, esifanele izindawo eziphansi zokushisa noma izimo lapho ukwakhiwa okusheshayo kuyadingeka. Ukwandiswa kwesikhathi sepulasitiki kunomthelela omkhulu ekwenzeni ngcono ukusebenza kokhonkolo.

I-Antifros inomsebenzi wokuvikela ukhonkolo ngaphansi kwezimo zokushisa eziphansi, ezingenza ikhonkrithi yakhiwe ngokujwayelekile ngaphansi kwezindawo zokushisa eziphansi, futhi ivimbele ukhonkolo ekuqiniseni kancane kancane ngenxa yokushisa okuphansi, okuthinta ukuthuthukiswa kwamandla.

Ama-preservatives asetshenziselwa ukumelana nokugqwala ezindaweni ezihlukahlukene futhi athuthukise ukuqina kukakhonkolo.

Lezi zixube ezivamile zekhonkrithi zinezici zazo kanye nokusetshenziswa kwazo. Ukukhetha okulungile nokusetshenziswa kungathuthukisa kakhulu ukusebenza kokhonkolo osulungile futhi kuthuthukise ukusebenza kahle kanye nekhwalithi yayo yonke iphrojekthi. Ukuqonda ukusebenza nokusetshenziswa kwezixube ezahlukahlukene kuzosiza abenzi bezinqumo zobunjiniyela ukuthi bakhethe izixube ngokwesayensi nangendlela ephusile futhi bathuthukise ukusetshenziswa kobunjiniyela

ukhonkolo osulungile.

Ukuhlaziywa okuqhathanisayo kwezingxube ezihlukene kukhonkolo osulungile:

Isinciphisi samanzi siyingxube kakhonkolo exubile evame ukusetshenziswa. Umsebenzi wayo oyinhloko ukunciphisa ukusetshenziswa kwamanzi kokhonkolo ngaphandle kokushintsha ukuhlukaniswa nokufana kwekhonkrithi, ngaleyo ndlela kuthuthukiswe ukusebenza kanye namandla okukhonkolo.Ukunciphisa inani lamanzi asetshenziselwa ukhonkolo olungele ukuxuba kunomthelela omkhulu kwikhwalithi. Umthelela oyinhloko ukuthuthukiswa kwamandla kakhonkolo. Lokhu kungenxa yokuthi inani lamanzi adingekayo ekuphenduleni kwe-cement hydration liyancishiswa, ukuze kusetshenziselwe amanzi amaningi ukukhiqiza imikhiqizo ye-hydration, ngaleyo ndlela kwandiswe ukuhlangana phakathi kwezinhlayiya zesigaba esiqinile nokuthuthukisa amandla. Ukusetshenziswa kokunciphisa amanzi kungathuthukisa ukuqina kokhonkolo. Imikhiqizo eyenziwe usimende hydration kukhonkolo ingagcwalisa ama-pores, inciphise i-porosity, futhi inciphise ukuxhuma kwe-pore, ngaleyo ndlela ithuthukise izinkomba zokuqina zikakhonkolo ezifana nokungangenisi kanye nokumelana nesithwathwa.
