High-Strength Concrete Mix

High-strength pob zeb yog tsim los ua kom muaj zog compressive siab dua li cov tsoos pob zeb sib xyaw.Ntawm no yog ib daim ntawv qhia dav dav txog kev sib tov cov pob zeb muaj zog:

1. Xaiv cov khoom zoo:

• Siv cov ntaub ntawv zoo, suav nrog Portland cement, aggregates, dej, thiab admixtures, los xyuas kom meej qhov xav tau lub zog thiab kav ntev ntawm cov pob zeb.
• Xaiv qhov zoo-qib aggregates nrog cov khoom muaj zog, ruaj khov los txhim kho kev ua tau zoo tag nrho ntawm cov pob zeb sib xyaw.

2. Txiav txim siab Mix Design:

• Ua haujlwm nrog tus kws tsim khoom tsim nyog lossis tus neeg tsim khoom ua vaj tse los tsim kev sib xyaw tsim kom haum rau cov kev xav tau tshwj xeeb ntawm koj qhov project.
• Qhia meej lub hom phiaj compressive zog, aggregate gradation, cement cov ntsiab lus, dej-cement ratio, thiab lwm yam additives los yog additives xav tau kom ua tau raws li cov khoom xav tau.

3. Kev faib cov khoom xyaw:

• Muab xam cov proportions ntawm cement, aggregates, thiab dej raws li kev sib xyaw tsim specifications.
• High-strength pob zeb feem ntau muaj qis dej-cement piv thiab cov cement ntau dua piv rau cov qauv sib xyaw ua ke los txhim kho lub zog.

4. Kev npaj sib tov:

• Siv lub pob zeb sib tov uas muaj peev xwm ua tau zoo sib xws thiab sib xyaw ua ke, xws li lub nruas tov khoom lossis lub tshuab paddle.
• Pib los ntawm kev ntxiv ib feem ntawm cov aggregates rau lub tov khoom, ua raws li cov cement thiab cov khoom ntxiv cementitious (SCMs) yog tias xav tau.
• Sib tov cov khoom xyaw qhuav kom huv si kom huv si sib faib thiab txo qis kev sib cais.

5. Ntxiv dej:

• Maj mam ntxiv dej rau lub tov khoom thaum sib tov cov khoom xyaw qhuav kom ua tiav qhov kev xav tau ua haujlwm thiab sib xws.
• Siv cov dej zoo, huv si tsis muaj impurities uas tuaj yeem cuam tshuam kev ua haujlwm ntawm cov pob zeb.

6. Admixture Ntxiv (Yeem):

• Muab cov khoom siv ntxiv lossis cov khoom ntxiv, xws li superplasticizers, air-entraining agents, lossis pozzolans, txhawm rau txhim kho kev ua haujlwm, lub zog, durability, lossis lwm yam khoom ntawm cov pob zeb sib xyaw.
• Ua raws li cov chaw tsim khoom pom zoo rau cov nqi ntau npaum li cas thiab cov txheej txheem sib xyaw thaum ntxiv cov khoom sib xyaw.

7. Cov txheej txheem sib xyaw:

• Sib tov cov pob zeb kom zoo rau lub sijhawm txaus kom ua tiav cov dej ntawm cov cement thiab sib faib ntawm txhua cov khoom xyaw.
• Tsis txhob overmixing los yog undermixing, raws li ib tug yuav cuam tshuam rau kev ua hauj lwm, lub zog, thiab durability ntawm pob zeb.

8. Kev Tswj Xyuas Zoo:

• Ua cov kev ntsuam xyuas zoo li niaj zaus, suav nrog kev ntsuas qis, ntsuas huab cua, thiab ntsuas lub zog compressive, txhawm rau txheeb xyuas qhov sib xws thiab kev ua tau zoo ntawm cov pob zeb sib xyaw ua haujlwm siab.
• Kho qhov sib tov sib xyaw lossis cov txheej txheem sib xyaw ua ke raws li qhov xav tau raws li cov txiaj ntsig kev xeem kom ua tiav cov khoom xav tau.

9. Kev tso chaw thiab kho:

• Muab cov pob zeb ua kom muaj zog sib xyaw kom sai tom qab sib xyaw kom tsis txhob muaj qhov teeb meem ntxov thiab ua kom muaj kev sib koom ua ke thiab ua tiav.
• Muab kev kho kom zoo los ntawm kev siv dej los yog siv cov tshuaj tua kab mob kom tswj tau cov dej noo thiab qhov kub thiab txias ua rau cov cement hydration thiab txhim kho lub zog.

10. Kev saib xyuas thiab tu:

• Saib xyuas qhov kev ua tau zoo thiab kev coj tus cwj pwm ntawm cov pob zeb muaj zog thaum muab tso rau, kho, thiab kev pabcuam lub neej kom paub txog tej yam teeb meem lossis qhov tsis zoo.
• Ua raws li kev saib xyuas thiab kev tiv thaiv kom tsim nyog los xyuas kom meej lub sijhawm ntev thiab kev ua haujlwm ntawm cov qauv tsim nrog cov pob zeb muaj zog.

Los ntawm kev ua raws li cov lus qhia no thiab ua haujlwm ze nrog cov kws tshaj lij, koj tuaj yeem ua tiav kev sib xyaw ua kom muaj zog ua kom haum raws li cov kev xav tau tshwj xeeb thiab kev ua tau zoo ntawm koj qhov kev tsim kho.
