Abakhiqizi bama-ejenti anciphisa amanzi bakhiqiza ama-ejenti anciphisa amanzi, futhi lapho bethengisa ama-ejenti anciphisa amanzi, bazophinde banamathisele ishidi elixubile lezinto ezinciphisa amanzi. I-Water-cement ratio kanye ne-concrete mix ratio ithinta ukusetshenziswa kwei-polycarboxylate superplasticizer. I-Polycarboxylate superplasticizerszizwela kakhulu ekusetshenzisweni kwamanzi okukhonkolo. Lapho kulungiswa ukhonkolo we-C50 kuphrojekthi, isilinganiso sokuqala samanzi nosimende sasingu-0.34%. Ukuhlolwa kwathola ukuthi uketshezi olumanzi lwalungeluhle, ngakho isilinganiso samanzi nosimende salungiswa saba ngu-0.35%, futhi ukusetshenziswa kwamanzi nge-cubic meter ngayinye kukhuphuke ngamakhilogremu amaningana.
Nakuba ukuwohloka kunyukile, kusekhona ukugeleza okukhulu ngisho nokuhlukaniswa, okuthinta ukufana okuphelele kokhonkolo. Ukwengeza inani elincane le-ejenti yokugcina amanzi kubangele inkinga enkulu kuyunithi yokwakha. Isilinganiso sesihlabathi sikakhonkolo siphinde sithinte umphumela wokusetshenziswa kwe-poly Carboxylate superplasticizer. Uma kusetshenziswa ama-ejenti okunciphisa amanzi asebenza kahle kakhulu asetshenziswa kakhulu, isilinganiso sesihlabathi singandiswa ngokufanelekile futhi uketshezi lukakhonkolo lungathuthukiswa.
Uma ixubene nei-polycarboxylate superplasticizer, isilinganiso sesihlabathi siphezulu futhi uketshezi lukakhonkolo lumpofu. Uchungechunge lomkhiqizo wei-polycarboxylate superplasticizerama-agent okunciphisa amanzi ohlobo ane-air intrainment aqukethe izakhi zofuzo ze-carboxyl adsorption futhi inenani elikhulu lamagatsha. Amaketanga aseceleni e-polyether ahlinzeka ngesithiyo se-steric, kuyilapho ama-polyethers enezindawo eziphefumulayo.
Ngenxa yomehluko ezinkambisweni zokukhiqiza kanye nomehluko wesisindo samangqamuzana ezintweni ezingavuthiwe ezisetshenziswa abakhiqizi abahlukene, kukhona futhi umehluko omkhulu emandleni wokungenisa umoya. Phakathi kwemikhiqizo eminingana ye-poly Carboxylate superplasticizer esiyihlolile, izinga eliphansi lokopha lalingu-3% kuphela, eliphakeme lalingu-6%, kanti eminye imikhiqizo yaze yafinyelela ku-8%.
Ngakho-ke, lapho usebenzisa ama-agent okunciphisa amanzi asezingeni eliphezulu, kuyadingeka ukwenza ukuhlolwa ngaphambi kokusetshenziswa okusemthethweni, bese uxuba ngokuvumelana nesimo sangempela sephrojekthi.
