1.Idosi ye-polycarboxylate superplasticizer ye-agent yokunciphisa amanzi inkulu kakhulu, kwaye kukho amaqamza amaninzi kakhulu kumphezulu wesakhiwo sekhonkrithi.
Ukususela kumbono wokumpompa kunye nokuqina, kunenzuzo ukunyusa ngokufanelekileyo iimpawu zokungenisa umoya.Uninzi lwee-polycarboxylate zokunciphisa amanzi zineempawu eziphezulu zokungenisa umoya.Imixube yokunciphisa amanzi esekwe kwipolycarboxylic acid nayo inendawo yokugcwala efana ne-naphthalene esekwe kwi-admixtures yokunciphisa amanzi.Kwiindidi ezahlukeneyo zesamente kunye needosi ezahlukeneyo zesamente, iindawo zokuzalisa le admixture kwikhonkrithi zihlukile.Ukuba isixa se-admixture sisondele kwindawo yokuhluthwa kwayo, ukuchithwa komxube wekhonkrithi kunokuphuculwa kuphela ngokulungelelanisa inani le-slurry kwikhonkrithi okanye ukusebenzisa ezinye iindlela.
I-Phenomenon: Isikhululo esithile sokuxuba sisebenzisa i-agent ye-polycarboxylic acid-based-based-agent yokunciphisa amanzi ukulungiselela ikhonkrithi ixesha elithile.Ngequbuliso ngenye imini, isiza sokwakha sabika ukuba emva kokususa i-formwork yodonga lokucheba, kwafunyaniswa ukuba kukho amaqamza amaninzi kakhulu phezu kodonga kwaye ukubonakala kubi kakhulu.
Isizathu: Ngomhla wokugalelwa kwekonkile, indawo yokwakha yanika ingxelo kaninzi ukuba ukudilika kwakuncinane kwaye nolwelo lwalungekho mgangathweni.Abasebenzi abasemsebenzini kwilabhoratri yesikhululo sokuxuba ikhonkrithi bandise inani lemixube.Isiza sokwakha sasebenzisa i-formwork enkulu yentsimbi emile, kwaye izinto ezininzi zongezwa ngexesha elinye ngexesha lokugalelwa, okubangele ukungcangcazela okungalinganiyo.
Uthintelo: Yomeleza unxibelelwano kunye nesiza sokwakha, kwaye ucebise ukuba ubude bokutya kunye nendlela yokungcangcazela iqhutywe ngokungqongqo ngokuhambelana neenkcukacha.Ukuphucula i-fluidity yomxube wekhonkrithi ngokulungelelanisa ubuninzi be-slurry kwikhonkrithi okanye ukusebenzisa ezinye iindlela.
I-2.I-agent ye-Polycarboxylate yokunciphisa amanzi ixutywe kakhulu kwaye ixesha lokumisela lide.
Isenzeko:Ukudilika kwekhonkrithi kukhulu, kwaye kuthatha iiyure ezingama-24 ukuba ikhonkrithi igqitywe.Kwisiza sokwakha, iiyure ezili-15 emva komqadi wesakhiwokwagalelwa ikhonkrithi, kwaxelwa kwisikhululo sokuxuba ukuba inxalenye yekhonkrithi yayingekaqini.Isikhululo sokuxuba sathumela injineli ukuba ihlole, kwaye emva kokufudumeza unyango, ukuqina kokugqibela kuthatha iiyure ezingama-24.
Isizathu:Ubungakanani beminyaka yokunciphisa amanzint inkulu, kwaye ubushushu be-ambient buphantsi ebusuku, ngoko ke i-concrete reaction reaction iyacotha.Abasebenzi bothula imithwalo kwindawo yokwakha bagalela amanzi ngokufihlakeleyo kwikonkile, edla amanzi amaninzi.
Uthintelo:Isixa somxube shifaneleka kwaye umlinganiselo kufuneka uchaneke.Siyakukhumbuza ukuba ubeke ingqalelo kwi-insulation kunye nokugcinwa xa iqondo lokushisa kwindawo yokwakha liphantsi, kwaye i-polycarboxylic acid admixtures ivakalelwa kukusetyenziswa kwamanzi, ngoko ungafaki amanzi ngokuthanda.
