Ama-Superplastizers kunganciphisa inani lamanzi asetshenziselwa ukuxuba ukhonkolo okungenani nge-10%, noma ukukhulisa kakhulu izinga lokugeleza ukhonkolo. Okwezinkomba ezineminyaka engu-3 izinsuku, amandla e-砼 C30 angakhushulwa ngo-69 MPA, futhi amandla ukhonkolo ezinsukwini ezingama-28 ubudala anyuswa afinyelela ku-87 MPA. Esetshenziswa kakhuluAma-Superplastizersikakhulukazi ama-polyalkylyl aryl sulfonate kanye namanzi anciphisa ama-melamine anciphisa ama-ejenti.

Imiphumela yeAma-Superplastizers ekusebenzeni kokhonkolo ikakhulukazi ngokulandelayo:

1. Ngokulandela izakhiwo zikakhonkolo ezihlanganisiwe. Ukuze amanzi anciphise umphumela we-superplastimizer, usayizi wamamolekyuli nohlobo oluthile lwesakhiwo se-ejenti yokunciphisa amanzi okusetshenzisiwe kufanele futhi lubhekwe. Umphumela womoya ophuma ogwini lwe-ejenti yokunciphisa amanzi uthinteka ekungethelweni komhlaba kwesisombululo esinamanzi. Lapho umthamo wengxabano enkulu uncishisiwe, kusobala ukuthi kucace kakhudlwana umoya womoya. Ngokwesikhathi sokhonkolo, uNaphthalene noMelamine bangathuthukisa isikhathi sokuhlangana kokhonkolo, kanye ne-superplastizer superplastizer banganciphisa isikhathi. Yize i-superplastizer ingaguquki kumamitha ahlukene, ukusetshenziswa kweAma-Superplastizers kunganciphisa ukuhlukaniswa kanye ne-exteding phenomena. Ukushiswa kokhonkolo kungathuthukiswa ngokufakwa kwe-superplastimizer. Isikhathi esithile esishukumisayo kanye nezinga elithile linqunywa ngokuqondile ngamapharamitha afana nohlobo nenani lamanzi anciphisa i-ejenti esetshenzisiwe.

2. Umphumela ezingxenyeni ezinzima zikakhonkolo. Usimende okufaka i-superplastizer ingathuthukisa izinga le-hydration. Ukucindezelwa kokhonkolo kanye namandla okugoba kwenziwa ngcono.Ama-Superplastizers Yehlisa futhi inani lesimende ngokushintsha inani le-shrinkage likakhonkolo. Kodwa-ke, ushintsho enani le-telescopic ngokuvamile alidluli inani elijwayelekile le-1x10-4.

3. Umthelela ekudakeni kokhonkolo. Amanzi asebenza kahle anciphisa i-ejenti ngempumelelo

kuthuthukisa i-anti-freeze kanye nezakhiwo ezi-anti-thaw zikakhonkolo ngenxa yezinga eliphakeme lokunciphisa amanzi kanye nenani le-trace yomoya ophahlayo. Futhi ukunciphisa amanzi asebenza kahle kungathuthukisa ngempumelelo amandla kakhonkolo ukuze amelane nokugqwala kwe-sulfuric acid. Ukuhlolwa kukhombisile ukuthi ukumelana neSulfuric Acid Cornision ye-superplastimizer akukubi ukwedlula lokho kukhonkolo okungenalutho.

4. Umphumela wokuvikelwa wokulwa nokuwohloka kwemigoqo yensimbi. Ukhonkolo onamandla okunciphisa amanzi asebenza kahle angahlobisa kahle ngemigoqo yensimbi, kanye nokunamathela kwensimbi eqondile-slide to ukhonkolo 7d kungathuthukiswa kusuka ku-1.2MPA kuye ku-8.5MPA. Ukunamathela kwensimbi ekhonyisiwe kukhonkolo 7d kungandiswa kusuka ku-15mpa kuya ku-27.5mpa. I-superplastizer nayo ingavikela ngempumelelo insimbi ngokhonkolo.
