Umphumela wokusebenza kahle kwe-ejenti enyuswe ngamanzi kukhonkolo okusha:
Ukuqina: Ukungeza i-ejenti ephezulu yokunciphisa amanzi kungakhulisa uketshezi lukakhonkolo; Ukuncipha kokhonkolo kukhuphuka ngokwanda kokusebenza okuphezulu kwe-agent emthanjeni. Lapho umthamo ufinyelela ku-0.75%, ukukhuphuka kwe-slump kufinyelela ngaphezulu. Lapho umthamo ukhuphuka ngokuqhubekayo, ukuncipha kwanda, kepha ukukhuphuka kuvame ukuba mnene. Ukuncipha kukakhonkolo okungeziwe ngokusebenza kahle kwamanzi okunciphisa amanzi kulahlekelwa ngokushesha, ngokuvamile kulahlekelwa iningi le-slump kungakapheli ihora eli-1, futhi kukhulu lapho izinga lokushisa liphezulu. Ngokuvamile, umthamo ofanele wokuphakanyiswa okuphezulu okunciphisa amanzi ngu-0,5% ~ 0.75%. Lapho inani likasimende likhulu, umthamo ofanele ngu-0.9% ~ 1.2%. Ngokombono wezomnotho, umthamo osetshenziswa kaningi cishe u-0.5%.
Isikhathi sokuphambuka: Umenzeli ophakeme wokunciphisa amanzi awunamthelela omncane ngesikhathi sokhonkolo. Uhlobo kanye nomthamo wokusebenza kahle kwe-ejenti okunciphisa amanzi kuhlukile, futhi izinga lethonya lihlukile; Umphumela we-ejenti esebenza ngempumelelo ekhulisa kakhulu ekuhlelweni kwawo uhlukile ezinhlotsheni ezihlukile zikasimende. Njengoba kukhonjisiwe kuThebula 1, isikhathi sokusetha sika usimende esingezwe nge-ejenti evuselelwa ngamanzi esebenza kahle.
I-OrbleEding: Ukungeza i-ejenti ephezulu yokunciphisa amanzi ukuze ukhonkolo inganciphisa isilinganiso sayo sokopha. Usebenzisa i-ejenti enciphisa amanzi nge-causative Properties (njenge-AF noJian-1) kunganciphisa izinga lokucima ngokwengeziwe. Ukuze ukhonkolo oxutshwe nosimende ojwayelekile, izinga lokugqwala kukakhonkolo elixutshwe ne-FDN, i-UNIV, CRS kanye namanzi ancishisiwe acishe abe ngu-50% kakhonkolo ojwayelekile.
Okuqukethwe ④air: Khulisa okuqukethwe komoya kokhonkolo. Okuqukethwe komoya kwe-CRS, i-FDN, futhi kukhuphuka ngo-1%, ukungezwa kwe-AF noJian-1 kungu-0.75%, kanye nokuqukethwe komoya kuka-5% cishe ngo-5%. Futhi qaphela ukuthi okuqukethwe komoya kukakhonkolo ogelezayo kuzokwehla lapho ungeza i-ejenti evuselelwa ngamanzi ephezulu.
⑤Heat of hydration: Ukushisa kwe-hydration kanye ne-peak lokushisa lika usimende okuhlanganiswe ne-ejenti evuselelwa ngamanzi asondelene ne-agent enamandla asondelene nalawo masimende ngaphandle kwama-admixtures, kepha isikhathi esiphakeme sokushisa sibambezelwa ngamahora ambalwa. I-ejenti esebenza kahle kakhulu yokunciphisa amanzi inciphisa ukushisa kwe-hydration of slag cement. Bona iThebula 2 Ukushisa kwe-hydration of usimende ehlanganiswe ne-ejenti ephakeme kakhulu yokunciphisa amanzi.
