I-Concrete Admixtures, okukhulunywa ngayo njenge-admixtures ngamafuphi, bheka izinto ezingezwe ngaphambi noma ngesikhathi sokuxuba kokhonkolo ukuze uthuthukise izakhiwo zikakhonkolo omusha kanye / noma ukhonkolo olukhuni. Izici ze-commectite admixtures zinhlobonhlobo eziningi futhi
umthamo omncane, odlala indima ebalulekile ekuguqulweni kokhonkolo. Ngokuthuthuka kancane kancane kwemboni yezokwakha, isidingo sokhonkolo kumaphrojekthi wobunjiniyela siyaqhubeka sanda, futhi ngasikhathi sinye, kunezidingo eziphakeme zokusebenza kwekhwalithi. Kulesi simo, njengezinto zobunjiniyela ezibalulekile ezingakhulisa kakhulu ukusebenza kokhonkolo, ama-admixtures kakhonkolo asephenduke isamba esiyisihlanu esisemqoka esingukhonkolo sanamuhla ngaphandle kosimende, isihlabathi, itshe namanzi.
I-ejenti yokunciphisa amanzi ephakeme kakhulu ihlukaniswe ngezigaba ezintathu: umenzeli ojwayelekile wokunciphisa amanzi, ukusebenza kahle kwe-ejenti ephakeme ngamanzi kanye ne-ejenti yokunciphisa amanzi ephezulu. Ukuthuthukiswa kwama-superplastizer kudlule ezigabeni ezintathu: isizukulwane sokuqala sama-superplastizer ajwayelekile amelelweukhuni calcium, isizukulwane sesibili sama-superplastizer amelweI-Naphthaleneuchungechunge, nesizukulwane sesithathu sama-superplastifizer amelwepolycarboxylate superplastimizerUchungechunge. Isizukulwane sesigaba esiphakeme se-superplastimizer.Polycarboxylate superplastimizerinezinzuzo zemithamo ephansi kanye nokwehliswa kwamanzi okuphezulu, futhi ingasetshenziselwa ukwakha amandla aphezulu, i-Ultra-high amandla aphezulu, ukuqina okuphezulu kanye nokhonkolo oluphezulu lwe-super-fluid; Inqubo ayinawo uketshezi lwemfucuza, igesi yokungcola, ukungcola kokuhlanzeka kwezinto nezinye izinto. Kuyinto eluhlaza okotshani futhi enobungane obuphezulu bokunciphisa i-ejenti, futhi inezinzuzo ezisobala ekuvikelweni kwemvelo nasekusebenzeni kahle. Ngokwanda kwekhono lokukhiqiza kanye nokwenza ngcono okungcono, ama-superplastimizer ama-superplastizer asephenduke izinhlobo eziphambili zama-superplastizers akhiqizwa futhi aqedwe ezweni lami.
Ngokwesimo "sokukhula okuqinile" kulindeleke ukuthi siqhubeke nokushisa, ukwanda kwesidingo sikakhonkolo esilethwe ngokwanda kwamaphrojekthi amakhulu wobunjiniyela kanye nenqubekela phambili yokwakha kuzonyusa isidingo sama-admixtures asonke at ngasikhathi sinye. Ngaphezu kwalokho, ngokusho kwemibiko yoMsebenzi Kahulumeni okhishwe yizifundazwe ezahlukahlukene, ukwakhiwa kwengqalasizinda okufana nokuhamba namaphrojekthi wamanzi we-akhawunti enkulu yamaphrojekthi amakhulu, kanti amaphrojekthi angenhla anezidingo eziphakeme zokusebenza ngokhonkolo, kanye namanzi asebenza kahle Ama-Drusers ayadingeka ukuze ahlangabezane nezidingo zikakhonkolo. Uma kuqhathaniswa nezinye izinhlobo ze-admixtures, izidingo zokwakha zokupompa kanye nokwehliswa kwe-vibration kanye nezidingo zamahhala ezivelayo zamaphrojekthi okhonkolo akhethekile anezinzuzo ezisobala. Ngakho-ke, ingxenye yesidingo sama-ejenti aphezulu ancishisiwe amanzi angafinyelela "amaphrojekthi wezobunjiniyela" enziwe "alindelwe ukuthi andise futhi.
I-Jufu Chemical Comnical Company Ibhizinisi lezinto ezibonakalayo ngaphandle kwebhizinisi eliyinhloko lama-superplastizers libonisa umbono ongaphansi komkhiqizo ohluke kakhulu kubaqhudelana. Ngokuzayo, izokwazi ukuphinda impumelelo yebhizinisi le-superplastimizer, futhi uphahla lwesikhala semakethe luphakeme kakhulu kunalokho kwama-superplastizer.
