Imininingwane enzuzo
Indlela yokuthumela:Ezokuthutha ngomhlaba, Ezokuthutha ngolwandle
Ukubonisa umlingani
I-concrete water reducer uhlobo lwe-concrete admixture, umsebenzi wayo oyinhloko ukunciphisa inani lamanzi okuxuba 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 sokuhamba) kuhlala kungashintshi, amanzi okuxuba angancishiswa ngo-10%–30%.
Lapho isilinganiso samanzi-okubopha (isilinganiso samanzi nezinto ezibopha) sincishiswa, ubukhulu bamachashaza angaphakathi kukakhonkolo buyancipha, okuholela esakhiweni esiqinile. Ekugcineni, lokhu kuthuthukisa kakhulu izici zokuqina njengamandla okucindezela, ukungangeni kwamanzi, nokumelana nomoya obandayo.
Umphumela wokwenza ipulasitiki (umphumela wokuhamba)
Uma ukusetshenziswa kwamanzi kungashintshi, i-slump yekhonkrithi ingakwazi ukwenyuka ibe ngaphezu kuka-180mm (ngisho nokufinyelela isimo sokugeleza okuphezulu nokuzihlehlisa) ngemuva kokungezwa kwe-water reducer.
Lo mphumela wenza ikhonkrithi kube lula ukuyipompa, ukuyothela, nokuyinyikimisa, okufanele kakhulu ekwakhiweni kwekhonkrithi enevolumu enkulu, ikhonkrithi eyi-pumped, nezingxenye eziyinkimbinkimbi ezinezinsimbi eziningi, kugwenywe amaphutha afana 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
Amanzi anciphisa ama-agent alungisa isakhiwo sangaphakathi samachashaza omoya kakhonkolo, anciphisa amachashaza axhumene, athuthukisa ngempumelelo ukungangeni kwamanzi, ukumelana nesulfidi, nokumelana ne-carbonation kukakhonkolo, futhi andise impilo yesevisi yezakhiwo zikakhonkolo.
