Izithasiselo zikakhonkolo ezingasindi | Ama-ejenti Akhipha Amagwebu Asebenza Kakhulu Wokhonkolo Weselula
Ama-Superplasticizers ayingxube yamakhemikhali engakhuphula ukusebenza kwezingxube zikakhonkolo noma zodaka ngokunciphisa i-viscosity yazo.. Zisetshenziselwa izinhlelo zokusebenza ezihlukahlukene ezifana nokusheshisa noma ukuhlehlisa isethi kasimende kwingxube kakhonkolo, ukuthuthukisa ikhono layo lokugeleza kanye nokunciphisa okuqukethwe kwayo kwamanzi kuze kufike 30% ngaphandle kokuthinta kakhulu amandla ayo. Lokhu kubaluleke kakhulu kumaphrojekthi wokwakha anezincazelo eziqinile zamandla okhonkolo okuqala kanye nesikhathi eside.
Kulesi sihloko, I-Riteks EvoTek 7015 ichazwa njengengxube yokunciphisa amanzi ebanga eliphakeme esetshenziselwa amaphrojekthi ahlukahlukene wokwakha ukwenza ukhonkolo uketshezi oluningi futhi kuncishiswe izimbobo zomoya kanye nama-voids kukhonkolo oqinile.. Lokhu kwenza kube lula ukubekwa kukakhonkolo, futhi yonga izindleko zabasebenzi ngenxa yokudlidliza okuncane.
Kuphinde kube yi-disasperant enamandla, esiza ngokufakwa kukasimende okungcono futhi ngenxa yalokho kuholela ekuthuthukisweni kwamandla kakhonkolo okuqala nesikhathi eside. Isakhiwo sekama esiyingqayizivele njengochungechunge oluseceleni kule polycarboxylate superplasticizer lungadonsa futhi luxoshe izinhlayiya zikasimende., okunikeza isenzo esinamandla sokuhlakazeka. Ingahlanjululwa kalula ngengxube yekhonkrithi ukuze unciphise isilinganiso samanzi-samente, futhi iyahambisana nePortland Cement (i-powder futhi ihlanganiswe).
Kulolu cwaningo, izinhlobo ezine ezahlukene superplasticizers, kuhlanganise ne-lignosulfonate, i-naphthalene, i-melamine, kanye ne-polycarboxylate, zazixutshwe nokugxiliswa okuhlukahlukene kwe-binder ku-CPB slurry. Khona-ke, Ukungaguquguquki kwe-slurry namandla kwahlolwa ngemva kwezikhathi ezihlukene zokukhipha amanzi. Imiphumela ibonisa ukuthi i-polycarboxylate superplasticizer ingcono kakhulu ngokwekhono layo lokunciphisa umthamo we-binder futhi igcine ukufana namandla kwe-CPB slurry..
