Njengoba izinga lokushisa liqhubeka nokukhuphuka, intwasahlobo iyeza, futhi okulandelayo umthelela wezinguquko zomehluko wokushisa ekwehleni kukakhonkolo. Mayelana nalokhu, sizokwenza izinguquko ezihambisanayo lapho sisebenzisa ama-ejenti anciphisa amanzi ukuze Ukhonkolo ufinyelele isimo esifunekayo.

1. Ama-ejenti okunciphisa amanzi e-Polycarboxylate asenezinkinga ngokuguquguquka kwawo kusimende. Kusimende ngamunye, izinga lokunciphisa amanzi liyoba liphansi futhi ukulahlekelwa ukuwohloka kuyoba kukhulu. Ngakho-ke, lapho ukuguquguquka kwesimenti kungalungile, ukuxuba kwesivivinyo nokulungiswa kwekhonkrithi kufanele kwenziwe. umthamo ukuze kuzuzwe imiphumela engcono kakhulu.

Ngaphezu kwalokho, ukuqina nesikhathi sokugcina usimende kuzophinde kuthinte ukusebenza kwe-polycarboxylate superplasticizer. Ukusetshenziswa kukasimende oshisayo kufanele kugwenywe ekukhiqizeni. Uma usimende oshisayo uxubene ne-agent yokunciphisa amanzi ye-polycarboxylate, ukuwohloka kokuqala kokhonkolo kuzoba lula ukuphuma, kodwa umphumela wokulondoloza i-slump we-admixture uzoba buthaka, futhi ukhonkolo ungase ubonakale. Ukulahlekelwa okusheshayo kokuwohloka.

2. Ama-ejenti okunciphisa amanzi e-Polycarboxylate azwela kakhulu ekushintsheni kwezinto ezingavuthiwe. Lapho izinga lezinto zokusetshenziswa ezifana nesihlabathi namatshe kanye nezingxube ezinjengomlotha wezimpukane nempushana yamaminerali lishintsha kakhulu, ama-ejenti okunciphisa amanzi e-polycarboxylate azohlanganiswa nama-ejenti anciphisa amanzi e-polycarboxylate. Ukusebenza kukakhonkolo kuzothinteka ngezinga elithile, futhi ukuhlolwa kwengxube yesilingo kufanele kwenziwe futhi ngezinto ezingavuthiwe ezishintshiwe ukuze kulungiswe umthamo ukuze kuzuzwe umphumela omuhle kakhulu.

3. I-ejenti yokunciphisa amanzi ye-polycarboxylate izwela kakhulu okuqukethwe kodaka kwe-aggregate. Udaka oluningi luzonciphisa ukusebenza kwe-ejenti yokunciphisa amanzi ye-polycarboxylate. Ngakho-ke, ikhwalithi yama-aggregates kufanele ilawulwe ngokuqinile uma usebenzisa i-polycarboxylate superplasticizers. Lapho okuqukethwe kodaka kweqoqo kukhuphuka, umthamo we-ejenti yokunciphisa amanzi ye-polycarboxylate kufanele unyuswe.

4. Ngenxa yezinga eliphezulu lokunciphisa amanzi le-ejenti yokunciphisa amanzi ye-polycarboxylate, ukuwohloka kokhonkolo kuzwela kakhulu ekusetshenzisweni kwamanzi. Ngakho-ke, ukusetshenziswa kwamanzi kokhonkolo kufanele kulawulwe ngokuqinile ngesikhathi sokusetshenziswa. Uma inani selidlulile, ukhonkolo uzovela ukuhlukaniswa, ukopha, ukuqina kanye nokuqukethwe komoya ngokweqile kanye nezinye izenzakalo ezimbi.

5. Uma usebenzisa i-polycarboxylate yokunciphisa amanzi axubile, kuhle ukwandisa ngokufanele isikhathi sokuxuba (ngokuvamile kabili ubude be-admixtures yendabuko) ngesikhathi sokukhiqiza ukhonkolo, ukuze ikhono lokuvimbela i-steric ye-polycarboxylate yokunciphisa amanzi admixture ingaba isetshenziswa kalula, elungele Ukulawulwa kokuwohloka kokhonkolo ekukhiqizeni. Uma isikhathi sokuxuba singanele, kungenzeka kakhulu ukuthi ukuwohloka kokhonkolo okulethwe endaweni yokwakha kuzoba kukhulu kunokwehla kokhonkolo okulawulwa esiteshini sokuxuba.

6. Ngokufika kwentwasahlobo, umehluko wokushisa phakathi kwemini nobusuku ushintsha kakhulu. Ekulawuleni ukukhiqiza, kufanele sihlale sinake izinguquko ekuweni kokhonkolo futhi silungise umthamo we-admixtures ngesikhathi esifanele (ukufeza isimiso sokuxuba okuphansi ekushiseni okuphansi nokuxuba okuphezulu ekushiseni okuphezulu).
