1.Isilinganiso se-ejenti yokunciphisa amanzi ye-polycarboxylate superplasticizer sikhulu kakhulu, futhi kunamabhamuza amaningi kakhulu ebusweni besakhiwo sikakhonkolo.
Ngokombono wokudonsa nokuqina, kuyazuzisa ukukhulisa ngokufanelekile izakhiwo zokungenisa umoya.Ama-ejenti amaningi anciphisa amanzi e-polycarboxylate anezindawo eziphakeme zokungenisa umoya.Izixube zokunciphisa amanzi ezisuselwe ku-Polycarboxylic acid nazo zinephoyinti lokugcwala njengezixube zokunciphisa amanzi ezisekelwe ku-naphthalene.Ezinhlotsheni ezahlukene zikasimende kanye nemithamo ehlukene kasimende, amaphuzu okugcwala ale ngxube ekukhonkoloni ahlukile.Uma inani le-admixture liseduze nendawo yalo yokugcwala, i-fluidity yengxube yekhonkrithi ingathuthukiswa kuphela ngokulungisa inani le-slurry kukhonkolo noma ukusebenzisa ezinye izindlela.
I-Phenomenon: Isiteshi esithile sokuxuba besisebenzisa i-ejenti yokunciphisa amanzi esekwe ku-polycarboxylic ukuze kulungiswe ukhonkolo isikhathi esithile.Kungazelelwe ngolunye usuku, indawo yokwakha yabika ukuthi ngemva kokususa udonga lokugunda, kwatholakala ukuthi kwakunamabhamuza amaningi kakhulu odongeni futhi ukubukeka kwakumpofu kakhulu.
Isizathu: Ngosuku lokuthela ukhonkolo, indawo yokwakha yabika izikhathi eziningi ukuthi ukuwohloka kwakuncane futhi uketshezi lwalungeluhle.Izisebenzi ezisemsebenzini elabhorethri yesiteshi sokuxova ukhonkolo zandisa inani lezixube.Indawo yokwakha yasebenzisa insimbi emise okwensimbi enkulu, futhi kwanezelwa izinto eziningi kakhulu ngesikhathi esisodwa ngesikhathi sokuthululwa, okuholela ekudlidlizeni okungalingani.
Ukuvimbela: Qinisa ukuxhumana nendawo yokwakha, futhi utuse ukuthi ubude bokudla kanye nendlela yokudlidliza kusetshenziswe ngokuqinile ngokuhambisana nezimfuneko.Thuthukisa i-fluidity yengxube kakhonkolo ngokulungisa inani le-slurry kukhonkolo noma usebenzisa ezinye izindlela.
2.I-ejenti yokunciphisa amanzi ye-Polycarboxylate ixubene kakhulu futhi isikhathi sokusetha siyandiswa.
Ukwenzeka:Ukuwa kukakhonkolo kukhulu, futhi kuthatha amahora angu-24 ukuze ukhonkolo ugcine umile.Endaweni yokwakha, amahora angu-15 ngemva komugqa wesakhiwokwathelwa ukhonkolo, kwabikwa esiteshini sokuxutshwa ukuthi ingxenye kakhonkolo ibingakaqini.Isiteshi sokuxuba sathumela unjiniyela ukuthi ayohlola, futhi ngemva kokwelashwa kokushisisa, ukuqiniswa kokugcina kwathatha amahora angu-24.
Isizathu:Inani leminyaka yobudala yokunciphisa amanzint inkulu, futhi izinga lokushisa le-ambient liphansi ebusuku, ngakho-ke ukusabela kwe-concrete hydration kuhamba kancane.Abasebenzi abethula impahla endaweni yokwakha bafaka amanzi ngasese kukhonkolo, odla amanzi amaningi.
Ukuvimbela:Inani lenhlanganisela shkufanele futhi isilinganiso kufanele sinembile.Sikukhumbuza ukuthi unake ukugqumisa nokunakekela lapho izinga lokushisa endaweni yokwakha liba phansi, futhi izingxube ze-polycarboxylic acid zizwela ukusetshenziswa kwamanzi, ngakho ungangezi amanzi ngokuthanda kwakho.
