Indlela yokuthumela:Ezokuthutha ngomhlaba, Ezokuthutha ngolwandle
Ukubonisa umlingani
I-concrete water reducer iwuhlobo lwe-concrete admixture, umsebenzi wayo oyinhloko ukunciphisa inani lamanzi okuxubha ngaphandle kokushintsha ukusebenza (ukugeleza, ukubambelela, ukugcinwa kwamanzi) kwekhonkrithi; noma ukuthuthukisa kakhulu ukugeleza kwekhonkrithi ngenkathi kugcinwa inani elifanayo lamanzi, ngaleyo ndlela kuthuthukiswe ukusebenza kanye nezakhiwo zemishini zekhonkrithi.
Ukuhlukaniswa kwemisebenzi eyinhloko
Umphumela wokunciphisa amanzi (umsebenzi oyisisekelo kakhulu)
Ngenkathi kuqinisekiswa ukuthi ukwehla kukakhonkolo (isilinganiso sokugeleza) kuhlala kungashintshi, amanzi okuxuba angancishiswa ngo-10%–30%.
Lapho isilinganiso samanzi-okubopha (isilinganiso samanzi nezinto ezibopha njengosimende) sincishiswa, ubukhulu bezimbotshana bangaphakathi buye banciphe, okuholela esakhiweni esiqinile. Ekugcineni, lokhu kuthuthukisa kakhulu izici zokuqina njengamandla okucindezela, ukungangeni kwamanzi, nokumelana nomoya obandayo.
Umphumela wokwenza kube lula (umphumela wokugeleza)
Uma ukusetshenziswa kwamanzi kungashintshi, i-slump yekhonkrithi ingakhuphuka ibe ngaphezu kuka-180mm (ngisho nokufinyelela isimo sokugeleza okuphezulu nokuzihlehlisa) ngemuva kokungezwa kwe-water reducer.
Lo mphumela wenza ikhonkrithi kube lula ukuyishova, ukuyothela, nokuyinyikimisa, okufanele kakhulu ekwakhiweni kwekhonkrithi enevolumu enkulu, ikhonkrithi eyishovayo, nezingxenye eziyinkimbinkimbi ezinezingxenye eziningi zokuvikela, kugwenywe iziphambeko ezifana nokunganyakazi okungaphelele, ukubola, kanye nezingaphezulu ezinamabala.
Gcina isamente
Ngaphansi kwesimiso sokugcina amandla kanye nokwehla kukakhonkolo, ukunciphisa ukusetshenziswa kwamanzi kunganciphisa ukusetshenziswa kwesimende (ngokuvamile ngo-5%–15%), kunciphise izindleko zobunjiniyela, futhi kunciphise ukushisa kwe-hydration yesimende, ngaleyo ndlela kunciphise inkinga yokuqhekeka kwezinga lokushisa kukakhonkolo omkhulu.
Thuthukisa ukuqina kukakhonkolo
Amajenera anciphisa amanzi enza kahle isakhiwo sangaphakathi sezimbotshana zikakhonkolo, anciphisa izimbotshana ezixhumene, athuthukise ngempumelelo ukungangeni kwamanzi, ukumelana nesulfidi, nokumelana ne-carbonation kukakhonkolo, futhi andise impilo yesevisi yezakhiwo zikakhonkolo.
