1. Ithonya lokuhlanganiswa:
Ukhonkolo osebenza kahle une-slag enhle nenani elikhulu lomlotha wempukane ekuhlanganiseni, kepha ushintsho ebusheni kanye nekhwalithi yokuhlanganiswa nethonya elikhulu ekusebenzeni kweI-ejenti ye-polycarboxylate amanzi ancishisiwe.Izinga le-Admixtures elingahlangabezani nezidingo lizothinta isimo sikakhonkolo omusha. Ngokuvamile, ukuguquguquka kwe-mineral powder kuhle, kepha isilinganiso sokuxuba sikhulu kakhulu futhi kulula ukopha. I-Fly Ash kufanele ilawulwe ngokuqinile ukuze uhlangabezane nezidingo zeleveli ezimbili nangaphezulu, futhi izinga lomlotha amabili linganciphisa kakhulu isilinganiso sokuncipha kwamanzi.
2. Ithonya lokunciphisa amanzi umthamo kanye nokusetshenziswa kwamanzi:
Kuzinhlelo zokusebenza ezisebenzayo, kunenkinga yomthamo ofanele wanoma yimuphi umenzeli we-ejenti. Umthamo owuthandayo uncike ohlotsheni lukasimende, inani lesimende kanye nekhwalithi yokuhlanganiswa. Ngaphambi kwesicelo sobunjiniyela, kuyadingeka ukuthola umthamo omkhulu kanye nokusetshenziswa kwamanzi okulungile (isilinganiso samanzi se-ningirind) sei-polycarboxylicsI-ejenti ye-Upenterplastizer enciphisa amanziNgokuxuba okuphindaphindiwe kwesivivinyo ngokuya ngemibandela kasimende kanye nama-admixtures. Kuhlelo lokusebenza lobunjiniyela, lalelisisa i-glue shintsha izinto zokhonkolo, bese ulungisa umthamo kancane ngokuya ngoshintsho, ukuze ukhonkolo omusha ungafinyelela isimo esidingekayo.
3. Ithonya lokuhlangana:
Inkomba yokuqukethwe ye-MUD yesihlabathi inethonya elikhulu ekusebenzeni kwamanzi okunciphisa amanzi, ikakhulukazi okuqukethwe kwesihlabathi sodaka. Lapho okuqukethwe kwe-MUD kukhulu kune-3%, ukusebenza komenzeli wokunciphisa amanzi kuncishiswa kakhulu. Kunzima ukuthola uketshezi okwanelisayo ngokukhulisa okuqukethwe. Ku-C30 in-indawo ekhonkolo yephrojekthi eJinan, lapho okuqukethwei-polycarboxylicsI-ejenti ye-Upenterplastizer enciphisa amanzi(I-NOFAS) ingu-1.0%, ingahlangabezana nobunzima nokukhishwa kwemali okudingekayo yiphrojekthi. Kodwa-ke, kuzinhlelo zokusebenza ezisebenzayo, ngenxa yokuqukethwe okuphezulu kodaka kwesihlabathi kanye ne-gravel (ikakhulukazi isihlabathi), uketshezi lukakhonkolo luvame ukwehla lapho kuxuba. Ngokuvamile, le nkinga ingaxazululwa ngokwandisa ngokufanele okuqukethwe kwamanzi okunciphisa i-ejenti. Kepha lapho okuqukethwe kwamanzi okunciphisa i-ejenti kukhuphuka ngenani elithile, akunakuhlangabezana nezidingo. Eminye imikhuba yokwakha ikhombisa ukuthi lapho okuqukethwe kodaka kukhulu kune-3%, umthelela e-ejenti yokunciphisa amanzi uyabonakala, kepha lapho okuqukethwe kwe-maud kukhulu kune-5%, umane wenyuse okuqukethwe yi-ejenti yokunciphisa amanzi ngeke kuxazulule i Inkinga.
Ngaphezu kwalokho, ithonya lokuhlelwa kwamatshe kanye nenani lezinambitha ezinjengezinazo ku-i-polycarboxylicsI-UperPlastizerkuyabonakala futhi. Ngaphansi kwesilinganiso esifanayo, okuqukethwe okufana nenaliti kwetshe kukhuphuka, okunciphisa uketshezi nokwelulwa kokhonkolo, futhi kuthambekele ezinkingeni zokopha nezinkinga zokwehla. Ngaphezu kokushintsha kakhulu isilinganiso sokuxuba ukhonkolo, kunzima ukufeza imiphumela egculisayo kuphela ngokushintsha okuqukethwe noma okuqukethwe komoya kweI-ejenti ye-polycarboxylate amanzi ancishisiwe.
