I-Superplasticistibers Unokunciphisa isixa samanzi asetyenziselwa ikhonkrithi yokuxuba ubuncinci i-10%, okanye ukwandisa kakhulu inqanaba lokuhamba kwekhonkrithi. Kwiintsuku ezi-3 zekhonkrithi ezi-3, amandla e-CC C3 anganyuswa nge-69 MPA, kunye namandla ekhonkrithi kwiintsuku ezingama-28 ubudala anyuka aye kwi-87 MPA. Isetyenziswa rhoqoI-Superplasticistibersikakhulu zii-polyalkyl aryl sulfonates kunye ne-melamine yokunciphisa iiarhente zokunciphisa amanzi.

Iziphumo zeI-Superplasticistibers Kwintsebenzo yekhonkrithi ikakhulu:

1. Ngokwemigangatho yekhonkrithi entsha exubeneyo. Kwisiphumo sokucutha amanzi e-superplastizer, ubungakanani bemoyari kunye nohlobo oluthile lwearhente yokunciphisa amanzi asetyenzisiweyo kufuneka kuthathelwe ingqalelo. Isiphumo somoya owodayo wokwenza iarhente encitshiswa kwamanzi ichaphazelekile kukungqubana komhlaba wesisombululo. Okukhona umda woxinzelelo lwempiwano encitshiswa, ecace ngakumbi isiphumo somoya. Ngokwexesha lokusetwa kwekhonkrithi, uNaphthalene kunye neMelamine banokuqhubela phambili ixesha lekhonkrithi, kunye ne-Sulfamate Superplaistihlo inokunciphisa ixesha lokuseta. Nangona i-superplastikizer ayiziqhelanisa neesaliti ezahlukeneyo, ukusetyenziswa kweI-Superplasticistibers inokunciphisa isahlulo kunye ne-phenomena. Ukutyibilika kwekhonkrithi kungaphuculwa ngokongezwa kwe-superplasticiezer. Ixesha lokutyibilika oluthile kunye nobungakanani bumiselwe ngokukodwa ziiparameter ezifana nohlobo kunye nenani lokunciphisa amanzi asetyenzisiweyo.

2. Impembelelo kwiipropathi ezikhulayo zekhonkrithi. Isamente ibandakanya i-superplasticiezer inokuphucula inqanaba le-hydration. Ukunyanzelwa kwekhonkrithi kunye nokugoba kuyaphucuka.I-Superplasticistibers Ikwanciphisa inani lesamente ngokutshintsha ixabiso le-shrinkage yekhonkrithi. Nangona kunjalo, utshintsho kwixabiso leTelescopic ngokubanzi alidluli kwixabiso eliqhelekileyo le-1x10-4.

I-3. Ifuthe lokuqina kwekhonkrithi. Ukunciphisa amanzi aphezulu okunciphisa amanzi ngokufanelekileyo

Iphucula iipropathi ze-anti-freze kunye ne-anti-thaw yekhonkrithi ngenxa yokunciphisa amanzi aphezulu kunye nenani lomoya ophumayo. Kwaye ukunciphisa amanzi aphezulu okunciphisa amanzi kunokuphucula ngokufanelekileyo amandla ekhonkrithi ukuxhathisa i-sulfuric sciosion. Iimvavanyo zibonakalise ukuba ukumelana nokuchasana ne-sulfuric scresion ye-superplasticiezer ayilunganga kunelo khonkrithi engenanto.

4. Impembelelo yokhuseleko lokukhusela i-anti-yosulelo lwemivalo yentsimbi. Ikhonkrithi enomgangatho wamanzi aphezulu onciphiso onokobhoda kakuhle ngemivalo yentsimbi, kunye nokunamathela kwentsimbi ethe tye ukuya kwikhonkrithi yekhonkrithi ye-7d ingaphuculwa ukusuka kwi-1.2MPA ukuya kwi-8.5MPA. Ukubiyela kwentsimbi yentsimbi kwikhonkrithi yekhonkrithi 7d kunokunyuswa ukusuka kwi-15MPA ukuya kwi-27.5MPA. I-Superplastikizer inokukhusela ngokufanelekileyo intsimbi kwikhonkrithi.
