Ngokombono womsebenzi wezingxube zekhonkrithi, singayeka ukuhlukaniswa futhi ngokuyinhloko sithinte izimo ezine. Ngokusebenzisa izixube ezifanele, singakwazi ukuqedela ukulawulwa kwejubane lokukhonkolo le-rheological. Ngokombono wokusetshenziswa kwezinhlobo ezahlukene ze-concrete admixtures, imiphumela nayo ihlukile. Okulandelayo, abakhiqizi be-concrete admixtures babelana ngokuhambisana ne-concrete admixtures.

Phakathi kwazo, umsebenzi oyinhloko we-ejenti yemvula ukunciphisa ukusetshenziswa kwamanzi ukuze kulungiswe, kunikeze ukhonkolo ngezakhiwo ezingcono zokuminyana kanye nokunwebeka, futhi kuthuthukiswe ukuqina kokusetshenziswa kwayo.

I-ejenti ye-air-entraining ukuyeka ukuqinisa ukuncibilika kokhonkolo ophansi, futhi uqedele ukulawulwa kwemifantu yangaphakathi kanye nokwenza kahle okuqhubekayo kokungena ngokusebenzisa ukuguqulwa okuphumelelayo kwesakhiwo sangaphakathi esikhonkolo.

Ngaphezu kwalokho, izicelo eziningi zekhonkrithi zinezidingo eziphezulu zokungangenisi. Abantu badinga ukuhlangabezana nezidingo zokwakha ngokusebenzisa i-ejenti yezulu esebenza kahle kakhulu ukuze kuthuthukiswe ukuminyana kukakhonkolo.Ngaphezu kwalokho, ukuqiniswa kukakhonkolo kujwayele ukugqwala, futhi abasebenzi abafanelekile bangakwazi ukulawula izinga le-carbonation likakhonkolo ngosizo ukusetshenziswa kwe-ejenti yemvula.Uma inani le-pH kukhonkolo libonisa inkambiso eyehlayo, inkinga yokugqwala kwebha yensimbi ehambisanayo nayo izovinjelwa ebangeni elikhulu.

Ngenxa yezinhlobonhlobo ezahlukene, ukukhethwa kwezingxube zekhonkrithi kuzophinde kubonise umehluko osobala. Ukuze kuboniswe umphumela ongokoqobo womsebenzi, izisebenzi ezifanele zidinga ukumisa ukulawula okunengqondo kwengxenye yezixube ngezici ezihlukahlukene zekhonkrithi, futhi zigcine ukuthuthukiswa okuphumelelayo kokusebenza kukakhonkolo ngokwako. Phakathi, i-ejenti yokunciphisa amanzi ingxube kakhonkolo enganciphisa ukusetshenziswa kwamanzi okuxutshwa ngaphansi kwesimo sokuthi ukuwohloka kukakhonkolo akushintshile. Ngemva kokwengeza ingxube kakhonkolo, ingahlakaza izinhlayiya zikasimende, ithuthukise ukusebenza kwayo, inciphise ukusetshenziswa kwamanzi eyunithi, futhi ithuthukise uketshezi lwengxube kakhonkolo; Noma unciphise ukusetshenziswa kukasimende ukuze wonge usimende.
