Izingxube zikakhonkolo, okubhekiselwa kuzo njengezixube kafushane, zibhekisela ezintweni ezengezwe ngaphambi noma ngesikhathi sokuxutshwa kukakhonkolo ukuze kuthuthukiswe izakhiwo zikakhonkolo omusha kanye/noma noma ukhonkolo oqinile. Izici ze-concrete admixtures ziyizinhlobonhlobo eziningi futhi

umthamo omncane, odlala indima ebalulekile ekuguquleni ukhonkolo. Ngokuthuthuka kancane kancane kwemboni yezokwakha, isidingo sokukhonkolo kumaphrojekthi wobunjiniyela siyaqhubeka nokwanda, futhi ngesikhathi esifanayo, kunezidingo eziphakeme zokusebenza kanye nekhwalithi yokukhonkolo. Kulo mongo, njengezinto ezibalulekile zobunjiniyela ezingathuthukisa kakhulu ukusebenza kukakhonkolo, izingxube zikakhonkolo seziyingxenye yesihlanu ebaluleke kakhulu kukhonkolo yesimanje ngaphandle kukasimende, isihlabathi, amatshe namanzi.

I-ejenti yokunciphisa amanzi esebenza kahle kakhulu I-ejenti yokunciphisa amanzi ihlukaniswe ikakhulukazi izigaba ezintathu: i-ejenti evamile yokunciphisa amanzi, i-ejenti yokunciphisa amanzi esebenza kahle kakhulu kanye ne-ejenti yokunciphisa amanzi esebenza kahle kakhulu. Ukuthuthukiswa kwama-superplasticizer kudlule izigaba ezintathu: isizukulwane sokuqala sama-superplasticizers ajwayelekile amelwei-calcium yokhuni, isizukulwane sesibili sama-superplasticizer amelelwa yii-naphthaleneuchungechunge, kanye nesizukulwane sesithathu sama-superplasticizer amelwei-polycarboxylate superplasticizeruchungechunge. Isizukulwane sesiteji se-superplasticizer esisebenza kahle kakhulu.I-Polycarboxylate superplasticizerinezinzuzo zomthamo ophansi kanye nokwehliswa kwamanzi okuphezulu, futhi ingasetshenziswa ukwenza ukhonkolo olunamandla amakhulu, amandla aphezulu kakhulu, ukuqina okuphezulu kanye nokhonkolo olunoketshezi oluningi; Inqubo ayinakho uketshezi olulahlwayo, igesi engcolile, ukukhishwa kwezinsalela zemfucuza nezinye izici. Kuyi-ejenti yokunciphisa amanzi eluhlaza futhi enobungani nemvelo esebenza kahle kakhulu, futhi inezinzuzo ezisobala ekuvikelweni kwemvelo nokusebenza kahle. Ngokunwetshwa komthamo wokukhiqiza kanye nokuthuthukiswa kokungena, ama-polycarboxylate superplasticizers abe yizinhlobo eziyinhloko zama-superplasticizers akhiqizwa futhi asetshenziswa ezweni lami.

Esimweni "sokukhula okuqhubekayo" okulindeleke ukuthi kuqhubeke ukushisa, ukwanda kwesidingo sikakhonkolo okulethwe ukwanda kokuhlelwa kwemiklamo emikhulu yobunjiniyela kanye nokuqhubekela phambili kweshejuli yokwakha kuzokwandisa isidingo sezinto ezixubene nokhonkolo. ngesikhathi esifanayo. Ngaphezu kwalokho, ngokwemibiko yemisebenzi kahulumeni ekhishwe izifundazwe ezehlukene, ukwakhiwa kwengqalasizinda njengamaphrojekthi ezokuthutha nokongiwa kwamanzi kubala ingxenye enkulu yamaphrojekthi amakhulu, kanti amaphrojekthi ashiwo ngenhla anezidingo eziphakeme zokusebenza kokhonkolo, kanye namanzi asebenza kahle kakhulu. abanciphisi bayadingeka ukuze bahlangabezane nezidingo zikakhonkolo. Uma kuqhathaniswa nezinye izinhlobo zokuxutshwa, izidingo zokwakha ukumpompa kanye nokunciphisa ukudlidliza kanye nezidingo ezingenazo ukudlidliza zamaphrojekthi kakhonkolo akhethekile anezinzuzo ezisobala. Ngakho-ke, ingxenye yesidingo sama-ejenti okunciphisa amanzi asebenza kahle kakhulu angafeza amaphrojekthi wobunjiniyela "enziwe ngomsiki" kulindeleke ukuthi akhule ngokuqhubekayo.

Ibhizinisi elisebenzayo le-Jufu Chemical Company ngaphandle kwebhizinisi eliyinhloko lamapulasitiki amakhulu libonisa umqondo womkhiqizo oyisisekelo ohluke kakhulu kunembangi yawo. Ngokuzayo, izokwazi ukuphindaphinda impumelelo yebhizinisi le-superplasticizer, futhi uphahla lwesikhala semakethe luphakeme kakhulu kunalolo lwama-superplasticizers.
