1. Umthelela wengxubevange:
Ukhonkolo osebenza kahle kakhulu une-slag enhle kanye nenani elikhulu lomlotha wempukane ku-admixture, kodwa ukuguqulwa kobuhle kanye nekhwalithi ye-admixture kunethonya elikhulu ekusebenzenii-ejenti yokunciphisa amanzi ye-polycarboxylate.Izinga le-admixtures elingahlangabezani nezidingo lizothinta kakhulu isimo sokhonkolo esisha. Ngokuvamile, ukuguquguquka kwe-mineral powder kuhle, kodwa isilinganiso sokuxuba sikhulu kakhulu futhi kulula ukopha. Umlotha we-fly kufanele ulawulwe ngokuqinile ukuze uhlangabezane nezidingo zezinga lesibili nangaphezulu, futhi umlotha wezinga lesibili unganciphisa kakhulu izinga lokunciphisa amanzi le-admixtures.
2. Umthelela wokunciphisa umthamo wamanzi nokusetshenziswa kwamanzi:
Ekusetshenzisweni okungokoqobo, kunenkinga yomthamo ophelele wanoma iyiphi i-ejenti yokunciphisa amanzi. Umthamo okhethwayo uncike ohlotsheni lukasimende, inani likasimende kanye nekhwalithi ye-admixture. Ngaphambi kokufaka isicelo sobunjiniyela, kuyadingeka ukuthola umthamo ophelele kanye nokusetshenziswa kwamanzi okuphelele (isilinganiso sokuhlanganisa amanzi)i-polycarboxylicsi-ejenti yokunciphisa amanzi ye-uperplasticizerngokuxutshwa kwesivivinyo ngokuphindaphindiwe ngokuvumelana nezimo zikasimende nezixube. Ekusetshenzisweni kobunjiniyela, qaphela kakhulu i-glue Shintsha izinto eziphathekayo, futhi ulungise umthamo kancane ngokusho koshintsho, ukuze ukhonkolo olusha lufinyelele esimweni esidingekayo.
3. Umthelela we-aggregate:
Inkomba yodaka lwesihlabathi inethonya elikhulu ekusebenzeni kwe-ejenti yokunciphisa amanzi, ikakhulukazi okuqukethwe kodaka esihlabathini. Lapho okuqukethwe kodaka kungaphezu kuka-3%, ukusebenza kwe-ejenti yokunciphisa amanzi kuncipha kakhulu. Kunzima ukuthola uketshezi olwanelisayo ngokwandisa okuqukethwe ngokufanelekile. Ku-C30 cast-in-place inqwaba ukhonkolo wephrojekthi eJinan, lapho okuqukethwe kwei-polycarboxylicsi-ejenti yokunciphisa amanzi ye-uperplasticizer(i-nofas) ingu-1.0%, ingahlangabezana nokuguquguquka nokunwebeka okudingekayo iphrojekthi. Kodwa-ke, ekusebenzeni okungokoqobo, ngenxa yodaka oluningi lwesihlabathi namatshe (ikakhulukazi isihlabathi), uketshezi lukakhonkolo luvame ukuncipha lapho kuxutshwa. Ngokuvamile, le nkinga ingaxazululwa ngokwandisa ngokufanelekile okuqukethwe kwe-ejenti yokunciphisa amanzi. Kodwa uma okuqukethwe kwe-ejenti yokunciphisa amanzi kukhuphukela enanini elithile, kusengakwazi ukuhlangabezana nezidingo. Ezinye izinqubo zokwakha zibonisa ukuthi lapho okuqukethwe kodaka kungaphezu kuka-3%, umthelela ku-ejenti yokunciphisa amanzi uyabonakala, kodwa lapho okuqukethwe kodaka kungaphezu kuka-5%, ukumane ukwandise okuqukethwe kwe-ejenti yokunciphisa amanzi ayikwazi ukuxazulula inkinga. inkinga.
Ngaphezu kwalokho, ithonya le-gradation yetshe kanye nenani lama-flakes afana nenaliti ku-i-polycarboxylicsi-uperplasticizerkuyabonakala futhi. Ngaphansi kwesilinganiso esifanayo, okuqukethwe kwetshe okufana nenaliti kuyanda, okunciphisa uketshezi nokwandiswa kwekhonkrithi, futhi kujwayele ukuphuma nezinkinga zokuhlukanisa. Ngaphezu kokulungisa kakhulu isilinganiso sokuxutshwa kukakhonkolo, kunzima ukuthola imiphumela egculisayo kuphela ngokushintsha okuqukethwe noma okuqukethwe komoyai-ejenti yokunciphisa amanzi ye-polycarboxylate.
