Ama-Superplasticizers inganciphisa inani lamanzi asetshenziselwa ukuxuba ukhonkolo okungenani ngo-10%, noma ikhulise kakhulu izinga lokugeleza kukakhonkolo. Ngokhonkolo oneminyaka engu-3 ubudala, amandla e-砼C30 anganyuswa ngo-69 mpa, futhi amandla kakhonkolo ezinsukwini ezingama-28 ubudala anyuswe abe okungenani ama-87 mpa. Okuvame ukusetshenziswaama-superplasticizersikakhulukazi i-polyalkyl aryl sulfonates kanye nama-ejenti okunciphisa amanzi e-melamine.

Imiphumela yeama-superplasticizers ekusebenzeni okukhonkolo ikakhulukazi kungokulandelayo:

1. Ngokuphathelene nezakhiwo zikakhonkolo osanda kuxutshwa. Ngomphumela wokunciphisa amanzi we-superplasticizer, usayizi wamangqamuzana kanye nohlobo oluthile lwesakhiwo se-ejenti yokunciphisa amanzi esetshenzisiwe kufanele futhi kucatshangelwe. Umphumela womoya wokopha we-ejenti yokunciphisa amanzi uthintwa ukungezwani okungaphezulu kwesixazululo esinamanzi. Lapho amandla okuqina angaphezulu encipha, kusobala kakhulu umphumela womoya wokopha. Ngokuphathelene nesikhathi sokusetha ukhonkolo, i-naphthalene ne-melamine ingaqhubekisela phambili isikhathi sokuhlanganisa ukhonkolo, futhi i-sulfamate superplasticizer inganciphisa isikhathi sokusetha. Nakuba i-superplasticizer ingavumelani nezimo ezihlukene zamasimende, ukusetshenziswa kweama-superplasticizers kunganciphisa ukuhlukaniswa kanye nezimo zokopha. Ukwehla kokhonkolo kungathuthukiswa ngokufakwa kwe-superplasticizer. Isikhathi esithile sokuwa kanye nezinga linqunywa ngokuqondile amapharamitha afana nohlobo nenani le-ejenti yokunciphisa amanzi esetshenzisiwe.

2. Umphumela wezakhiwo eziqinile zikakhonkolo. Usimende ohlanganisa i-superplasticizer ungathuthukisa izinga lokugeleza kwamanzi. Ukucindezelwa kukakhonkolo namandla okugoba kuyathuthukiswa.Ama-Superplasticizers futhi unciphise inani likasimende ngokushintsha inani le-shrinkage likakhonkolo. Kodwa-ke, uguquko lwenani le-telescopic ngokuvamile aludluli inani elijwayelekile lika-1X10-4.

3. Umthelela wokuqina kukakhonkolo. I-ejenti yokunciphisa amanzi esebenza kahle kakhulu

ithuthukisa izakhiwo zikakhonkolo zokunqanda ukuqhwa nokuncibilika ngenxa yezinga eliphezulu lokunciphisa amanzi kanye nokulandela inani lomoya owophayo. Futhi isinciphisi samanzi esisebenza kahle kakhulu singathuthukisa ngempumelelo ikhono likakhonkolo lokumelana nokugqwala kwe-sulfuric acid. Ukuhlola kubonise ukuthi ukumelana nokugqwala kwe-sulfuric acid ye-superplasticizer akukubi kakhulu kunokhonkolo ongenalutho.

4. Umthelela wokuvikela ukugqwala kwamabha ensimbi. Ukhonkolo onesinciphisi samanzi esisebenza kahle kakhulu singahlangana kahle nezinsimbi zensimbi, futhi ukunamathela kwensimbi yesilayidi eqondile ku-7D ukhonkolo kungathuthukiswa ukusuka ku-1.2MPA kuye ku-8.5MPA. Ukunamathela kwensimbi egobile ku-7D kakhonkolo kungandiswa kusuka ku-15MPA kuya ku-27.5MPA. I-superplasticizer nayo ingavikela ngempumelelo insimbi kukhonkolo.
