Kev tshuaj xyuas ua rau cov kaus poom nplaum nplaum:

Qhov tshwm sim ntawm qhov tshwm sim ntawm lub lauj kaub nplaum yog thawj zaug uas cuam tshuam nrog kev siv cov tshuaj txo cov dej. Lub luag haujlwm tseem ceeb ntawm cov dej-txo admixture yog txhawm rau txhim kho cov dej ntws ntawm cov pob zeb, tab sis yog tias nws xaiv tsis raug lossis ntxiv rau ntau dhau lawm, nws yuav ua rau cov pob zeb ua kom khov thiab ua raws li phab ntsa ntawm lub tank sib tov, ua rau nws ua rau cov pob zeb ua kom tsis muaj zog. nyuaj rau unload. Tsis tas li ntawd, cov khoom ntawm cov pob zeb raw cov ntaub ntawv kuj tseem muaj feem cuam tshuam rau lub lauj kaub sticking phenomenon. Piv txwv li, yam xws li cov tshuaj muaj pes tsawg leeg ntawm cov cement, particle loj faib ntawm aggregates, thiab av nkos cov ntsiab lus yuav cuam tshuam ncaj qha rau lub fluidity ntawm pob zeb. Thaum cov ntsiab lus ntawm qee cov khoom xyaw hauv cov khoom siv raw no siab dhau los yog qis dhau, nws tuaj yeem ua rau cov pob zeb nplaum thiab ua rau muaj teeb meem sticking. Nyob rau tib lub sijhawm, kev tswj xyuas kev ua haujlwm thaum lub sijhawm sib xyaw ua ke kuj yog qhov laj thawj tseem ceeb rau cov kaus poom nplaum. Yog tias lub sijhawm sib tov ntev dhau los lossis qhov sib tov nrawm dhau, qhov kub thiab kev sib txhuam ntau dhau tuaj yeem tsim nyob rau hauv cov pob zeb thaum lub sij hawm sib tov, uas ua rau muaj kev nce hauv cov viscosity ntawm cov pob zeb, uas yuav ua rau lub lauj kaub nplaum.

Txoj kev daws teeb meem rau cov nplaum tuaj yeem yog raws li hauv qab no:

Yuav kom daws tau qhov teeb meem ntawm cov kaus poom nplaum, peb yuav tsum xub pib nrog kev xaiv thiab siv cov tshuaj txo cov dej. Rau cov qauv tshwj xeeb thiab kev siv ib puag ncig ntawm cov pob zeb, peb yuav tsum xaiv cov khoom tsim nyog ntawm cov dej-txo tus neeg saib xyuas thiab tswj nws cov tshuaj kom nruj kom tsis txhob siv ntau dhau los ntawm kev ua kom cov viscosity ntawm pob zeb. Nyob rau tib lub sijhawm, kev ua kom zoo ntawm cov qauv pob zeb tseem yog qhov tseem ceeb. Los ntawm kev kho cov ntsiab lus tseem ceeb xws li dej-cement piv thiab xuab zeb tus nqi, peb tuaj yeem txhim kho qhov fluidity ntawm pob zeb, yog li txo qhov kev pheej hmoo ntawm lub lauj kaub nplaum.

Ntxiv rau cov kev ntsuas saum toj no, kev saib xyuas txhua hnub thiab kev hloov pauv ntawm kev noj zaub mov yog qhov tseem ceeb sib npaug. Tom qab txhua qhov kev siv, nco ntsoov ntxuav cov pob zeb uas seem hauv lub tov khoom hauv lub sijhawm kom paub meej tias cov phab ntsa sab hauv ntawm lub tank sib tov yog huv si thiab du, thiaj li tsim tau cov kev mob zoo rau kev sib tov tom ntej. Tsis tas li ntawd, kev kho qhov kev noj zaub mov zoo kuj yog ib qho kev daws teeb meem zoo. Piv txwv li, ua ntej sib tov cov aggregate thiab ib feem ntawm cov dej, thiab tom qab ntawd ntxiv cov cement, cov dej seem thiab cov dej txo tus neeg sawv cev. Qhov no yuav pab txhim kho cov uniformity thiab fluidity ntawm cov pob zeb thiab txo cov phenomenon sticking. . Yog tias qhov teeb meem tseem niaj hnub, koj yuav tsum xav txog kev hloov cov khoom sib tov thiab xaiv cov khoom sib tov nrog lub taub hau loj dua lossis ib qho kev quab yuam ua kom muaj zog los txhim kho qhov sib tov thiab daws qhov teeb meem ntawm cov kaus poom.
