Ukukhethwa kwezingxube zekhonkrithi:
(1) I-ejenti yokunciphisa amanzi ephumelelayo futhi esebenza kakhulu: Njengoba uketshezi lukakhonkolo lulungiswa ngokuyinhloko yi-ejenti yokunciphisa amanzi esebenza kahle kakhulu, umthamo ubiza u-1% kuya ku-2% wesisindo sikasimende; ukuze uthole ukhonkolo onezidingo ezikhethekile zamandla okuqala, sebenzisa usimende obeka ngokushesha noma Faka intuthu ye-silica; uma usebenzisa i-silica fume kokhonkolo okudinga ukumelana nokugqokwa, futhi lapho ukhonkolo womthamo omkhulu wamandla aphezulu udinga ukunciphisa ukushisa kwe-hydration, inani likasimende kufanele lincishiswe futhi kwengezwe intuthu ye-silica noma umlotha wempukane. Isikhathi sokuqala sokusetha sikakhonkolo esixutshwe ne-ejenti yokunciphisa amanzi esebenza kahle kakhulu side kunesokhonkolo ovamile. Uma inani likhulu, isikhathi sokusetha sokuqala siba side.
(2) I-ejenti yokungenisa umoya kanye ne-ejenti yokunciphisa amanzi efaka umoya-mpilo: Kudingeka ukuthi ibe nokumelana nesithwathwa okuphezulu kanye nokuminyana okuphezulu, futhi kufanele ihlanganiswe ne-ejenti efaka umoya noma i-ejenti yokunciphisa amanzi efaka umoya. Engeza inani elithile lokuqukethwe komoya kukhonkolo, futhi uma okuqukethwe komoya kukhuphuka ngo-1%, amandla azokwehla cishe ngo-5%. Ngakho-ke, lapho ulungiselela ukhonkolo wezinga eliphezulu, okuqukethwe komoya kufanele kube ngu-3%, futhi ama-agent afaka umoya kufanele asetshenziswe ngokuqapha. Kodwa-ke, ukusetshenziswa kwama-ejenti afaka umoya kunezinzuzo eziningi kunezimo ezingezinhle ekusebenzeni kokukhonkolo okufana ne-anti-freeze kanye ne-anti-permeability.
(3) Ukukhetha isinqamuleli sokuqanda: Uma usebenzisa ukhonkolo onamandla amakhulu ebusika, qala ngokukhetha isinqanda-qhwa esilungele izinga lokushisa elilindelekile phakathi nokuthela. Ngesikhathi sokwakhiwa, i-antifreeze ehlanganisiwe enokunciphisa amanzi, i-air-entraining, i-anti-freezing kanye nezingxenye zamandla okuqala zisetshenziswa. Umsebenzi oyinhloko we-antifreeze ehlanganisiwe yokuqala-amandla ukunciphisa ukusetshenziswa kwamanzi okuxutshwa kanye nokunciphisa kakhulu amanzi amahhala e-samente hydration, ngaleyo ndlela kuncishiswe inani lokuqandisa. I-ejenti yokungenisa umoya eyinhlanganisela ikhiqiza inqwaba yamabhamuza amancane avaliwe kukhonkolo omusha, okunciphisa amandla okukhulisa umthamo wokuqhwaza kukhonkolo, yehlise indawo yokuqandisa, futhi ivumele ukhonkolo ukuthi uqhubeke nokuthela emanzini emazingeni okushisa amabi. Ingxenye yamandla okuqala e-ejenti efaka umoya-mpilo isheshisa ukugeleza kwengxube futhi iqinise kusenesikhathi, ihlangabezane namandla abalulekile ngokushesha ngangokunokwenzeka futhi igweme ukulimala kwangaphambi kweqhwa. Ama-nitrate, ama-nitrites kanye nama-carbonates ayizingxenye zokunqanda ukuqhwa futhi azifanelekele ukuxutshwa kokhonkolo okugayiwe kanye nokuqinisiwe. Ukhonkolo wamanzi okuphuza kanye nobunjiniyela bokudla akufanele usebenzise izakhi ze-antifreeze eziqukethe i-chromium usawoti wamandla wangaphambi kwesikhathi, i-nitrite ne-nitrate. I-antifreeze equkethe izingxenye ze-urea akufanele isetshenziswe ezakhiweni zokuhlala nezakhiwo zezentengiselwano.
