4. Kev Ua Haujlwm Tau: Qhov yooj yim uas cov pob zeb tuaj yeem sib tov, tso, nias, thiab ua tiav kom ua tiav cov duab thiab qhov tiav xav tau.
5. Qhov Ceev: Qhov hnyav ib chav ntim ntawm cov pob zeb ua vaj tse, uas cuam tshuam rau nws qhov hnyav thiab cov yam ntxwv ntawm cov qauv.
6. Kev Ntsws thiab Kev Ntsws: Kev hloov pauv ntawm qhov ntim thiab kev hloov pauv raws sijhawm vim yog qhov ziab, qhov kub thiab txias hloov pauv, thiab kev thauj khoom tas mus li.
7. Kev nkag tau: Lub peev xwm ntawm cov pob zeb ua vaj tse los tiv thaiv kev hla ntawm dej, roj, thiab lwm yam khoom los ntawm nws cov qhov hws thiab cov hlab ntsha.

Cov Khoom Siv Ntxiv thiab Lawv Cov Haujlwm:

1. Cov Tshuaj Txo Dej (Superplasticizers): Txhim kho kev ua haujlwm thiab txo cov dej hauv cov khoom yam tsis muaj kev txo qis lub zog.
2. Cov Tshuaj Tiv Thaiv Cua: Tsim cov npuas me me los txhim kho kev tiv thaiv khov thiab yaj thiab ua haujlwm tau zoo.
3. Cov Khoom Uas Ua Rau qeeb: Ncua lub sijhawm teeb tsa kom ntev dua rau kev thauj mus los, kev tso, thiab lub sijhawm ua tiav.
4. Cov khoom siv ua kom nrawm dua: Ua kom lub sijhawm teeb tsa sai dua, tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov huab cua txias.
5. Cov Pozzolans (piv txwv li, Fly Ash, Silica Fume): Txhim kho lub zog, kev ruaj khov, thiab txo qhov permeability los ntawm kev cuam tshuam nrog calcium hydroxide los tsim cov cementitious compounds ntxiv.
6. Cov Fibers (piv txwv li, Hlau, Khoom Siv Hluav Taws Xob): Txhim kho kev tiv thaiv kev tawg, kev tiv thaiv kev cuam tshuam, thiab lub zog tensile.
7. Cov Tshuaj Tiv Thaiv Kev Xeb: Tiv thaiv cov hlau txhawb nqa kom tsis txhob xeb los ntawm chloride ions lossis carbonation.

Cov Piv Txwv Ntxiv Uas Pom Zoo:

• Cov piv txwv tshwj xeeb ntawm cov khoom ntxiv nyob ntawm cov yam xws li cov yam ntxwv ntawm cov pob zeb xav tau, cov xwm txheej ib puag ncig, thiab cov kev xav tau ntawm qhov project.
• Feem ntau cov piv yog qhia ua feem pua ​​ntawm qhov hnyav ntawm cov cement lossis tag nrho cov qhov hnyav ntawm cov pob zeb sib tov.
• Yuav tsum txiav txim siab txog cov tshuaj raws li kev kuaj hauv chaw kuaj mob, kev sib xyaw ua ke, thiab cov qauv kev ua tau zoo.

Kev Tswj Xyuas Zoo:

1. Kev Ntsuas Cov Khoom Siv: Ua kev ntsuam xyuas rau cov khoom siv raw (piv txwv li, cov pob zeb sib xyaw, cement, cov khoom ntxiv) kom ntseeg tau tias ua raws li cov qauv thiab cov lus qhia tshwj xeeb.
2. Kev Sib Xyaws thiab Kev Sib Tov: Siv cov cuab yeej ntsuas thiab ntsuas kom raug rau kev sib xyaw cov khoom, thiab ua raws li cov txheej txheem sib tov kom raug kom ua tiav kev sib xws thiab kev sib xws.
3. Kev Ntsuas Kev Ua Haujlwm thiab Kev Sib Xws: Ua cov kev ntsuas kev poob qis, kev ntsuas kev ntws, lossis kev ntsuas rheological los ntsuas kev ua haujlwm thiab kho cov feem sib tov raws li qhov xav tau.
4. Kev Kho Kom Zoo: Siv cov txheej txheem kho kom zoo (piv txwv li, kev kho kom noo noo, cov tshuaj kho kom zoo, cov ntaub so ntswg kho kom zoo) kom tiv thaiv kev qhuav ua ntej thiab txhawb kom muaj dej noo.
5. Kev Ntsuas Lub Zog: Saib xyuas kev txhim kho lub zog ntawm cov pob zeb los ntawm cov txheej txheem ntsuas tus qauv (piv txwv li, kev ntsuas lub zog compressive) ntawm ntau lub hnub nyoog kom paub tseeb tias ua raws li cov qauv tsim.
6. Cov Kev Pabcuam Kev Ruaj Ntseg Zoo/Kev Tswj Xyuas Zoo (QA/QC): Tsim kom muaj cov kev pabcuam QA/QC uas suav nrog kev tshuaj xyuas tsis tu ncua, kev sau ntawv, thiab kev kho kom raug kom ntseeg tau tias muaj kev sib xws thiab ua raws li cov lus qhia.

Los ntawm kev nkag siab txog cov yam ntxwv ntawm cov pob zeb ua vaj tse, xaiv cov khoom ntxiv kom tsim nyog, tswj cov piv ntawm cov khoom ntxiv, thiab siv cov kev ntsuas tswj kom zoo, cov neeg tsim kho tuaj yeem tsim cov pob zeb ua vaj tse zoo uas ua tau raws li qhov yuav tsum tau ua thiab ua kom cov qauv ruaj khov thiab siv tau ntev.
