Teem sijhawm tau nce li ib feem peb rau ib 10 degree txo qis hauv cov pob zeb txo rau 40 degrees Fahrenheit. Ua kom muaj kev qhuas zoo tuaj yeem pab txhawb cov teebmeem no ntawm cov chaw kub tsawg ntawm kev teeb tsa thiab muaj zog nce. Lawv yuav tsum ua kom tau raws li cov cai ntawm Astm C 494, cov qauv specifications rau cov tshuaj admixtures rau pob zeb.

JuFU muab cov tshuab ua vaj tse rau huab cua txias thiab cov qhob ua vaj tse rau dej tsis huv, uas tuaj yeem siv dav siv hauv kev tsim kho.

Dab tsi yog qhov zoo ntawm kev nplua ua ke

1. Raws li cov ntaub ntawv zoo li no muaj qhov zoo compactness thiab muaj zog dua thaum kev tsim kho, kev ua haujlwm ntau dua yog kev txhim kho zoo heev. Tus yuam sij tsis yog kom co hauv cov txheej txheem ntau lawm, uas txo lub pouring lub sijhawm thiab kev siv ua haujlwm, thiab kuj txo tus nqi zog.

2. Raws li tau hais ua ntej, vim tias tsis tas yuav muaj kev co, tsis muaj suab nrov, thiab tib neeg lub suab nrov ua haujlwm thiab txhim kho cov chaw ua haujlwm.

3. Los ntawm qhov kev xav ntawm kev tsim kho ntawm kev ua tau zoo, yuav tsis muaj npuas ntawm kev tsim kho thaum siv cov khoom no, cia ib leeg kho. Nyob rau tib lub sijhawm, nws cov degree ntawm kev ywj pheej yog siab heev, txawm tias qee cov duab sib txawv lossis cov qauv sib zog nrog kev siv ntom ntom ntom.

Dab tsi yog qhov kev ceev faj rau pob zeb sib xyaw:

1. Cov mixing host nruab nyob rau hauv daim ntawv lo txawv, tsis tsuas yog tias, tab sis kuj nyob ntawm cov khoom tshwj xeeb, yog li xaiv xaiv cov khoom siv uas tsim nyog thiab khoom siv tsim nyog.

2. Kev siv ntawm ib lub chaw nres tsheb lossis ob lub chaw nres tsheb nyob ntawm cov haujlwm tshwj xeeb. Yog tias muaj cov pob zeb loj uas yuav tsum tau muab nchuav rau ntawm ib zaug thiab cov cai rau nws zoo, nws yog qhov zoo dua los siv ob pawg ntawm cov nroj tsuag sib xyaw me me.
