Ukusetshenziswa kwamanzi okunciphiswa kwamanzi, ama-retaarders, nama-superplastizer

Amanzi anciphise amanzi, ama-retaarders, kanye nama-superplastizer ama-admixtures amakhemikhali asetshenziswa ngaphakathiUkuhlanganiswa KwekhonkoloUkuthuthukisa izakhiwo ezithile futhi uthuthukise ukusebenza kokhonkolo ngesikhathi saso esisha nesilukhuni. Ngamunye walaba bama-admixtureturetures unikeza inhloso eyingqayizivele, futhi bavame ukuqashwa emisebenzini yokwakha ukufezekisa izici zokhonkolo ezifiselekayo. Ake sihlole ukusetshenziswa kwama-reducers amanzi, ama-retaarders, nama-superplastizer ngemininingwane eminingi:

1. Ukuncishiswa kwamanzi:

INJONGO:

• Ukunciphisa okuqukethwe kwamanzi: Amanzi anciphise amanzi, abizwa nangokuthi ama-ejenti anciphisa amanzi noma amapulasitiki, asetshenziselwa ukunciphisa inani lamanzi adingekayo ekuxubeni ukhonkolo ngaphandle kokuyekethisa ukusebenza kwawo.

Izinzuzo ezibalulekile:

• Ukusebenza okwenziwe ngcono: Ngokunciphisa okuqukethwe kwamanzi, ama-water anciphise athuthukisa ukuwenza kanye nokuhlangana kwengxube yekhonkolo.
• Amandla akhulayo: ukuncishiswa kokuqukethwe kwamanzi kuvame ukuholela ekuqiniseni kokhonkolo okuphezulu nokuqina.
• Ukuqina okuthuthukile: ukhonkolo onamanzi anciphisayo kuvame ukuba lula ukuqeda, okuholela endaweni ebushelelezi.

Izicelo:

• Ukhonkolo Onamandla Amandla: Amanzi anciphise amanzi asetshenziswa kakhulu ekukhiqizweni kokhonkolo onamandla aphezulu lapho izilinganiso eziphansi zamanzi zibucayi.
• Ukupompa ukhonkolo: Benza lula ukumpompeni kokhonkolo amabanga amade ngokugcina ukungaguquguquki koketshezi okwengeziwe.

2. Abathengisi:

INJONGO:

• Ukubambezeleka kokubeka isikhathi: ama-retaarders ama-admixtures aklanyelwe ukwehlisa isikhathi sokubeka ukhonkolo, okuvumela isikhathi esengeziwe sokusebenza.

Izinzuzo ezibalulekile:

• Ukusebenza okunwetshiwe: AbakwaRetaarders bavimbela ukuhlelwa kukakhonkolo ngaphambi kwesikhathi, ukuhlinzeka isikhathi esithe xaxa sokuxuba, ukuhambisa nokubeka impahla.
• Okuncishisiwe ukuqhekeka: izikhathi zokubeka kancane kunganciphisa ingozi yokuqhekeka, ikakhulukazi ezimweni zezulu ezishisayo.

Izicelo:

• Isikhombisi Sezulu Esishisayo: Ezimweni lapho amazinga okushisa aphezulu angasheshisa ukuhlelwa kokhonkolo, ama-retaarders asiza ukuphatha isikhathi sokusetha.
• Amaphrojekthi amakhulu wokwakha: kumaphrojekthi amakhulu lapho ukuthutha kanye nokubekwa kokhonkolo kuthatha isikhathi eseluliwe.

3. Ama-Superplastizers:

INJONGO:

• Ukuthuthukisa Ukusebenza: Ama-Superplastifizer, abizwa nangokuthi ama-subvucers amanzi aphezulu, asetshenziselwa ukukhulisa kakhulu ukusebenziseka kokhonkolo ngaphandle kokukhulisa okuqukethwe kwamanzi.

Izinzuzo ezibalulekile:

• Ukusebenza okuphezulu: Ama-Superplastizers avumela ukukhiqizwa kokhonkolo osebenza kakhulu futhi ongenakugeleza ngesilinganiso esiphansi samanzi.
• Amandla akhuphuke: Njengokunciphisa amanzi, ama-superplastifizers anikela ngamandla kakhonkolo aphakeme ngokunika amandla isilinganiso esiphansi samanzi.

Izicelo:

• Ukhonkolo ozihlanganisa ngokuzihlanganisa (i-SCC): Ama-Superplastimizer ajwayele ukusetshenziselwa ukukhiqizwa kwe-SCC, lapho kudingeka khona ukugeleza okuphezulu nezakhiwo ezizimele.
• Ukhonkolo osebenza kakhulu: Kuzinhlelo zokusebenza ezifuna amandla aphezulu, ukuqina, kanye nokunciphiswa kokunye.

Ukucatshangelwa okuvamile:

1. Ukuvumelana: ama-admixtures kufanele ahambisane nezinye izinto ku-conkcrete mix, kufaka phakathi usimende, ama-aggregates, nezinye izengezo.
2. Ukulawulwa kwemithamo: Ukulawulwa okuqondile kwemithamo yokuhlanganiswa kubalulekile ekufezekiseni izakhiwo zokhonkolo ozifunayo. Ukusetshenziswa ngokweqile kungaholela emiphumeleni emibi.
3. Ukuhlola: Ukuhlolwa okujwayelekile kanye nezinyathelo zokulawula ikhwalithi kubalulekile ukuze uqinisekise ukusebenza kwe-Admixtures ku-conkcrete ethile.
4. Izincomo zomkhiqizi: Ukunamathela ezincomeni kanye nemihlahlandlela enikezwe umenzi we-admixture ibalulekile ekusebenzeni kahle.

Ekuphetheni, ukusetshenziswa kwamanzi anciphise amanzi, ama-retaarders, kanye nama-superplastizer ekuxubeni kokhonkolo kuhlinzeka ngezindlela ezahlukahlukene, kusuka ekusebenzeni okuthuthukisiwe kanye nezikhathi zokutshala ezengeziwe ukuze uhlele amandla nokuqina. Ukuqonda izidingo ezithile zephrojekthi yokwakha nokukhetha umphikisi noma inhlanganisela ye-admixtures efanelekile ukufeza izakhiwo zokhonkolo ozifunayo. Imidwebo yokuhlanganiswa kanye nemiklamo yokuxuba kokhonkolo kufanele ihlelwe ngokucophelela futhi ihlolwe ukuqinisekisa ukusebenza kahle nokuqina kokhonkolo omude.
