Cov tsev ua vaj tse yog ib qho kev tsim tawm loj ntawm tib neeg. Qhov tshwm sim ntawm cov qhob tau pib kev hloov pauv hauv keeb kwm ntawm tib neeg architecture. Daim ntawv thov ntawm qhob tsa admixtures yog qhov kev txhim kho loj hauv pob zeb ntau lawm.Qhov tshwm sim ntawm cov pob zeb ua rau batching
Nroj tsuag tau ua cov khoom tsim ntawm cov khoom siv ua vaj tse nyob rau ntawm txoj kev kev lag luam kev lag luam thiab kev txuag. Qhov no tseem tso rau pem hauv ntej ntau yuav tsum tau ua ntau dua ntawm kev tswj hwm zoo ntawm pob zeb ntau lawm, ua rau kev txhim kho txhua yam ntawm cov khoom zoo nyob rau xyoo tas los no. Nyob rau tib lub sijhawm, vim muaj qib qis ntawm kev tswj hwm zoo hauv kev tswj hwm hauv qee cov qhob npaj kom npaj ua qhov project zoo, thiab txawm tshwm sim. Lub tshuab ua lag luam zoo sib tsoo uas tsis tau ntsib hauv ntau dua 20 xyoo tau ua rau kev lag luam poob hnyav.
Cov ntsiab lus tseem ceeb uas ua rau tsis sib xws ntawm Insixtures thiab Maas:
Cov kev ua tau zoo ntawm cov qhob nyob ntawm tsis tsuas yog nyob rau ntawm cov haujlwm ntawm cov ntaub ntawv qhuav, tab sis kuj nyob ntawm qhov yoog raws li cov ntaub ntawv thiab cov qhob ke sib piv. Admixtures (dej reducers) yog tsis tau sib haum nrog cov cement, uas yog cov pob zeb ua tau zoo dhau los yog cov pob zeb nrawm dhau lawm, thiab cov kab nrib pleb dhau lawm hauv cov tswv cuab ua vaj tse.
Raws li lub thib tsib tivthaiv ntawm pob zeb ua, admixture cov nyiaj rau ib lub sijhawm me me, uas tuaj yeem txhim kho cov pob zeb sib luag, uas tuaj yeem txhim kho cov kev ua haujlwm ntawm kev tsim kho lossis txuag cov nqi Cov. Cov tshuaj tsw qab ntawm cov xis yuav tsum tsawg dua 25% ntawm cov dej ntawm cov cement loj, nws yuav tsim cov qauv flocculation kom qhwv cov dej hauv nws. Qhov kev sib ntxiv ntawm cov kev qhia tawm cov lus qhia nyob rau sab saum toj ntawm cov hloov pauv tau, yog li ntawd txoj cai tso dej qhwv los ntawm txoj cai flocculation cov qauv, yog li ntawd Cov dej ntau ntxiv tuaj yeem koom nrog hauv cov tshuaj tsw qab. , txhim kho kev ua si. Qhov loj ntawm cov adsorption ntawm Maas hais rau cov admixture thiab poob ntawm cov txiaj ntsig ntawm cov admixtance cuam tshuam cov admixtance ntawm admixture rau cov cement.
Qhov teeb meem ntawm kev tsis sib xws ntawm inmixtures thiab xis mas yog ib qho teeb meem uas txhawj xeeb thiab mob taub hau rau txhua yam kev lag luam ua lag luam ua lag luam. Tom qab cov teeb meem tshwm sim, nws kawg cem rau ntawm admixture. Qhov tsis sib xws ntawm admixture thiab cov cement yog tshwm sim los ntawm tus admixture nws tus kheej. Cov ntsiab lus ntawm kev ua tau zoo thiab tshuaj lom neeg muaj feem xyuam rau cov neeg muaj feem ntau yog cov cement thiab emix-polycarboxylic acid-based superplasticizer yuav tshwm sim.
