I-3. Inyathelo lesenzo seSuperplasticindizers

Indlela yokuphucula amanzi i-fluelity yokuphucula ulwelo lomxube wekhonkrithi ubukhulu becala ubandakanya iziphumo zokusasaza kunye nefuthe lokuthambisa. Iarhente yokunciphisa amanzi yi-surfacnt, enye isiphelo se-molecular inyibilika ngokulula emanzini - i-Hydrophilic qela, kwaye esinye isiphelo singenamali emanzini - Iqela le-hydrophobic.

a. Ukusasazeka: Emva kokuba isamente ixutywe namanzi, ngenxa yokulayishwa kwe-molecular yamasuntswana, i-cemetions slimes yesakhiwo, ukuze i-10% yamanzi asongelwe kwi-suble amasuntswana kwaye akanakuthatha inxaxheba simahla ukuhamba kunye nokuthambisa. Isiphumo, ngaloo ndlela ichaphazela ulwelo lomxube wekhonkrithi. Xa kuvuswa amanzi e-arhente, kuba iimolekyuli zearhente ezincitshiswayo zinokuqiniseka kumphezulu wamasuntswana, umphezulu wesamente unetyala elifanayo (elihlala liyinto ebonakalayo), ikhuthaza ukusasazeka kwamasuntswana e-ceames kunye nokutshatyalaliswa kwesakhiwo seShedCast. , khupha indawo esongelweyo yamanzi kwaye uthathe inxaxheba ekuhambeni, ngaloo ndlela kwandisa ngokufanelekileyo ulwelo lomxube wekhonkrithi.

b. I-Lubrice Ukumelana phakathi kwamasuntswana ekhuni, ngaloo ndlela kuphuculwe ukwenza ulwelo lwekhonkrithi.

Iziphumo zokunciphisa amanzi kwikhonkrithi, njl.

a. Seta ixesha. I-Superplasticichiers ngokubanzi ayinasiphumo, kwaye inokuthi ikhuthaze i-hydration kwaye ikhuselwe isamente. I-superplastiki i-superplastither yinxalenye ye-Superplasticiezer kunye nombulelo. Phantsi kweemeko eziqhelekileyo, ukwenzela ukulibazisa i-hydiment yesamente kunye nokunciphisa ilahleko yokufakelwa, inani elithile longezwa kwi-arhente enciphisa amanzi.

b. Umxholo wegesi. Okwangoku, i-polycarbants esetyenziswe ngamanzi ePolycarbaple ye-Polycarbaple inomxholo womoya othile, kwaye umxholo womoya wekhonkrithi akufuneki ukuba uphakame kakhulu, kungenjalo kumandla ekhonkrithi aya kuncitshiswa kakhulu.

c. Ukugcinwa kwamanzi.

I-Superplastickibers ayinanzi lukhulu ekunciphiseni ukopha ikhonkrithi, kwaye isenokunyusa ukopha. Ikhonkrithi eyopha ingqungquthela xa idosi igqithisile.
