Njengoba izinga lokushisa liqhubeka likhuphuka, intwasahlobo iyeza, futhi yini elandelayo umthelela wokwehluka kokushisa umehluko wokushisa ngokhonkolo kakhonkolo. Kulokhu, sizokwenza izinguquko ezihambisanayo lapho sisebenzisa amanzi anciphisa ama-ejenti ukuze ukhonkolo ufinyelela esimweni esifunekayo.

1. I-Polycarboxxylate agents ekhuthazayo yamanzi anezinkinga ngokuzivumelanisa nezimo zayo. Okwezimo ngakunye, izinga lokunciphisa amanzi lizobe liphansi futhi ukulahleka okunciphayo kuzoba kukhulu. Ngakho-ke, lapho ukuzivumelanisa nezimo kasimende akukuhle, ukuhlanganiswa kwesivivinyo nokulungiswa kokhonkolo kufanele kwenziwe. umthamo ukuze uzuze imiphumela emihle kakhulu.

Ngaphezu kwalokho, isikhathi nesikhathi sokugcina usimende sizothinta futhi ukusebenza ngempumelelo kwe-polycarboxylate superplastimizer. Ukusetshenziswa kukasimende oshisayo kufanele kugwenywe ekukhiqizweni. Uma usimende oshisayo uxutshwe ne-ejenti ye-polycarboxylate yokunciphisa amanzi, ukuncibilika kokuqala kokhonkolo kuzoba lula ukuphuma, kepha umphumela wokugcina wokuthambisa ubuthakathaka uyoba buthaka, ukhonkolo kungavela. Ukulahleka okusheshayo kwesikhumba.

2. Ama-polycarboxxylate agents anciphisa amanzi azwela kakhulu ezinguquko ezintweni ezisetshenziswayo. Lapho ikhwalithi yezinto zokwenziwa eziluhlaza ezinjengesihlabathi nezinto zokwakha amatshe kanye nama-admixtures anjenge-fly ash kanye nama-mineral powder ashintsha kakhulu, ama-polycarboxylate agents ancishiswe amanzi ancishiswe ama-polycarboxylate ancents ancusy ancusylate agents. Ukusebenza kokhonkolo kuzothinteka ngezinga elithile, futhi ukuhlolwa kwecala lokuhlonza kufanele kwenziwe futhi ngezinto zokusetshenziswa ezishintshiwe ukuze kuguqulwe umthamo ukuze uzuze umthamo ukuze uzuze umphumela omuhle kakhulu.

I-3. I-ejenti ye-polycarboxylate yamanzi izwakala ikakhulukazi kokuqukethwe kwe-maud kwesihlanganisi. Okuqukethwe ngokweqile kodaka kuzonciphisa ukusebenza kwe-ejenti ye-polycarboxylate yokunciphisa amanzi. Ngakho-ke, ikhwalithi yama-aggregates kufanele ilawulwe ngokuqinile lapho usebenzisa i-polycarboxylate superplastizers. Lapho okuqukethwe kodaka kukhuphuka, umthamo we-polycarboxylate ejenti yokunciphisa amanzi kufanele andiswe.

4 Ngakho-ke, ukusetshenziswa kwamanzi kukakhonkolo kufanele kulawulwe ngokuqinile ngesikhathi sokusetshenziswa. Lapho inani lidluliwe, ukhonkolo kuzovela ukuhlukaniswa, ukopha, ukuqina nokuqukethwe komoya ngokweqile nezinye izinto ezingezinhle.

5. Lapho usebenzisa ama-polycarboxxylate anciphisa ama-admixtures, kungcono ukukhulisa ngokufanele isikhathi sokuxuba (ngokuvamile okuphindwe kabili kunawo wonke ama-admixtures wendabuko) ngesikhathi sokukhiqiza i-polycarboxylate ukuncipha kwamanzi Kusetshenziswe kalula, okulungele ukulawula ukuncipha kokhonkolo ekukhiqizeni. Uma isikhathi sokuxuba sekwanele, kungenzeka ukuthi ukuncibilika kokhonkolo okulethwe kusayithi yokwakha kuzoba mkhulu kunokwehla kokhonkolo olawulwa esiteshini sokuxuba.

6. Ngokufika kwentwasahlobo, umehluko wokushisa phakathi kwemini nobusuku ushintsha kakhulu. Ekulawuleni kokukhiqizwa, kufanele ngaso sonke isikhathi sinake izinguquko kukhonkolo ukhonkolo futhi silungise umthamo we-admixtures ngendlela efike ngesikhathi (finyelela umgomo wokuxuba okuphansi ezindaweni zokushisa eziphansi).
