Ukunciphisa amanzi abakhiqizi abenzi be-ejenti bakhiqiza ama-ejenti anciphisa amanzi, futhi lapho bethengisa ama-ejenti anciphisa amanzi, bazophinde banamathisele ishidi lokuxuba lamanzi anciphise abenzeli. Isilinganiso samanzi kanye nesilinganiso sokuxubana kokhonkolo kuthinta ukusetshenziswa kwepolycarboxylate superplastimizer. Ama-Polycarboxylate Superplastizersbazwela kakhulu ukusetshenziswa kwamanzi kokhonkolo. Lapho ulungiselela ukhonkolo we-C50 kuphrojekthi ye-Project of, isilinganiso sokuqala se-Design Water-Cement Ratio kwakungu-0.34%. Isivivinyo sathola ukuthi uketshezi lwalumpofu, ngakho-ke isilinganiso samanzi samanzi sashintshwa saba ngu-0,35%, futhi ukusetshenziswa kwamanzi ngemitha ye-cubic inyuke ngamakhilogremu ambalwa.
Yize i-slump inyukile, kusekhona inani elikhulu le-seepage ngisho nokuhlukaniswa, okuthinta ukufana ngokuphelele kokhonkolo. Ukungeza inani elincane le-ejenti yokugcina amanzi kubangele inkathazo eningi yeyunithi yokwakha. Isilinganiso sesihlabathi sokhonkolo sibuye sithinta umphumela wohlelo lokusebenza lwe-polyboxylate superplastizer. Lapho usebenzisa ama-ejenti avame ukunciphisa amandla asetshenzisiwe, isilinganiso sesihlabathi singanda ngokufanele futhi uketshezi lukakhonkolo lungathuthukiswa.
Lapho kuxutshwe nepolycarboxylate superplastimizer, isilinganiso sesihlabathi siphezulu futhi uketshezi lukakhonkolo lumpofu. Umkhiqizo uchungechunge lwepolycarboxylate superplastimizerThayipha amanzi anciphisa ama-ejenti ngokufakwa komoya aqukethe izinhlobo ze-carboxyl adsorption futhi unenani elikhulu lamagatsha. Amaketanga aseceleni kwama-polythere anikezela ngesithiyo esikhulu, ngenkathi ama-polyethers enezakhiwo eziningi eziphefumulayo.
Ngenxa yokwehluka kwezinqubo zokukhiqiza kanye nokwehluka kwesisindo kwamangqamuzana ezintweni ezisetshenziswayo ezisetshenziswa abakhiqizi abahlukahlukene, kunomehluko omkhulu kumthamo wokufaka umoya. Phakathi kwemikhiqizo eminingana ye-polyboxylate superplastimizer esiyihlolile, isilinganiso esiphansi sophale sasingama-3% kuphela, okuphezulu kwakungu-6%, kanti eminye imikhiqizo yaze yafinyelela ku-8%.
Ngakho-ke, lapho usebenzisa ama-ejenti akhulisa amanzi aphezulu, kuyadingeka ukwenza ukuhlolwa ngaphambi kokusebenzisa okuhlelekile, bese uxuba ngokuya ngesimo sangempela sephrojekthi.
