1.Imbano ye-polycarboxylate superplastimizer i-ejenti yokunciphisa amanzi inkulu kakhulu, futhi kunama-bubble amaningi kakhulu ebusweni besakhiwo sokhonkolo.
Ngokombono wokuncipha nokuqina, kuyazuzisa ukwandisa kahle izakhiwo zokufaka umoya. Ama-polycarboxxoxxelate agents anciphisa amanzi anezakhiwo eziphezulu zokufaka umoya. Ama-polycarboxbylic acid acid aciding admixtures acijile futhi anendawo yokugcwaliseka njengama-naphthalene-based manting admixtures. Ngezinhlobo ezahlukene zesimende kanye nemithamo yokonga ohlukile, amaphuzu wokugcwaliswa kwalolukhonkolo kukhonkolo ahlukile. Uma inani lokuhlanganiswa liseduze nephuzu lokugcwaliseka kwalo, uketshezi lwengxube ekhonkolo lungathuthukiswa kuphela ngokulungisa inani le-slurry kukhonkolo noma ngokusebenzisa ezinye izindlela.
I-Phenomenon: Isiteshi esithile sokuxuba sisebenzisa i-polycarboxylic acid-based ecing agent esuselwa kumanzi ukulungiselela ukhonkolo isikhathi esithile. Ngokuphazima kweso ngolunye usuku, kwabika indawo yokwakha ngemuva kokususa amafomu odonga lwe-shear, kwatholakala ukuthi kwakukhona ama-bubble amaningi ngaphezulu kodonga nokubukeka kwakumpofu kakhulu.
Isizathu: Ngosuku lokuthela ukhonkolo, kwakhiwa indawo yokwakha kaningi ukuthi ukuncibilika kwakukuncane futhi uketshezi lwalumpofu. Abasebenzi abasemsebenzini ngelebhu yesiteshi sokuxuba kokhonkolo bandisa inani le-admixtures. Isayithi lokwakha lasebenzisa amafomu amakhulu ensimbi akhiwe, futhi izinto eziningi zangezwa ngasikhathi sinye ngesikhathi sokuthulula, okuholela ekudleni okungalingani.
Ukuvimbela: Qinisekisa ukuxhumana nesayithi yokwakha, bese uncoma ukuthi ukuphakama kokuphakelayo kanye ne-vibration indlela kusebenze ngokuqinile ngokuya ngezincazelo. Thuthukisa uketshezi lwe-conkcrete mix ngokulungisa inani le-slurry kukhonkolo noma usebenzisa ezinye izindlela.
I-ejenti ye-Whent -BoxExExExEx juluka ixubene kakhulu futhi isikhathi sokusetha siye eside isikhathi eside.
IPhenomenoni:Ukushiswa kokhonkolo kukhulu, futhi kuthatha amahora angama-24 ukhonkolo ekugcineni ekugcineni. Endaweni yokwakha, amahora angu-15 ngemuva kogongolo oluhlelekileKuthulwe ukhonkolo, kubikwa esiteshini sokuxuba le ngxenye kakhonkolo ebingakaqinisekiswa. Isiteshi sokuxuba sathumela unjiniyela ukubheka, nangemva kokushisa, ukuqina kokugcina kwathatha amahora angama-24.
Isizathu:Inani leminyaka ekhulisa amanziI-NT inkulu, futhi izinga lokushisa elikhona liphansi ebusuku, ngakho-ke ukusabela kokhonkolo kwe-hydration kuhamba kancane. Abasebenzi beLahliwe endaweni yokwakha bangezela ngasese amanzi kukhonkolo, odla amanzi amaningi.
Ukuvimbela:Inani le-admixture shKufanelekile futhi isilinganiso kufanele sinembile. Sikukhumbuza ukuthi unake ukufakwa kanye nokunakekelwa lapho izinga lokushisa elisendaweni yokwakha liba yindawo ephansi, futhi ama-polycarboxylic acid admixtures azwela ukusetshenziswa kwamanzi, ngakho-ke ungangezi namanzi ngentando.
