Yuav ua li cas kom zoo sib xyaw ua si qhob?

Sib tov ua vaj tse yog qhov tseem ceeb kom ntseeg tau lub zog, durability, thiab kev ua haujlwm ntawm cov khoom kawg. Ntawm no yog cov lus qhia ib qib zuj zus los ntawm yuav ua li cas kom zoo sib xyaw ua si av:

1. Sau cov ntaub ntawv thiab khoom siv:

• Portland cement
• Aggregates (xuab zeb, gravel, lossis crushed pob zeb)
• Ywg dej
• Nws cov thawv ntim khoom (tshuab raj, pob zeb ua khoom, lossis sib xyaw tub)
• Ntsuas cov cuab yeej (thoob, duav, lossis sib xyaw)
• Tiv thaiv cov iav (hnab looj tes, kev nyab xeeb tsom iav, thiab daim npog ntsej muag)

2. Xam cov tshuaj tiv thaiv:

• Txiav txim siab qhov yuav tsum tau ua ntu zus ntawm cov cement, thiab dej raws li qhov xav tau pob zeb sib xyaw, cov zog yuav tsum tau ua, thiab npaj siab thov.
• Cov sib piv sib xyaw xws li 1: 2: 3 (Maas: Tsaus Xuab Zeb: Sau qoob loo) rau cov kev siv hauv paus siab thiab 1: 3 rau cov ntawv thov siab dua.

3. Npaj kev sib xyaw:

• Xaiv lub tiaj tiaj, theem rau kev sib xyaw ua ke kom ntseeg tau tias muaj kev ruaj khov thiab yooj yim ntawm kev tuav.
• Tiv thaiv thaj tsam sib xyaw los ntawm cua thiab ncaj qha tshav ntuj, uas tuaj yeem ua rau ziab ntxov kom qhuav ntawm cov pob zeb ua kom qhuav.

4. Ntxiv cov khoom xyaw qhuav:

• Pib los ntawm kev ntxiv cov ntsuas ntsuas ntsuas ntawm cov khoom xyaw qhuav (xis mas, xuab zeb, thiab aggregate) rau cov thawv sib xyaw.
• Siv tus duav los yog sib xyaw npog kom qhuav cov khoom xyaw qhuav, kom muaj kev faib tawm cov kev faib tawm thiab tsis txhob muaj clumps.

5. Maj mam ntxiv dej:

• Maj mam ntxiv dej rau qhov qhuav sib tov thaum txuas ntxiv sib xyaw kom ua tiav qhov kev xav tau.
• Zam kev ntxiv cov dej ntau dhau, ua rau dej ntau dhau yuav ua rau tsis muaj zog thiab ua rau cais thiab shrinkage backing.

6. Sib xyaw kom huv si:

• Sib tov cov qhob kom huv si kom txog thaum txhua cov khoom xyaw muaj covyees faib thiab cov sib tov muaj qhov tsis zoo.
• Siv ib rab yaj phom, hoe, lossis sib xyaw ua ke kom tig cov pob zeb ua kom tiav, ua kom txhua lub hnab yas qhuav yog sib xyaw thiab tsis muaj cov khoom siv qhuav nyob.

7. Tshawb xyuas xwm yeem:

• Kuaj lub sib xws ntawm cov pob zeb ua los ntawm kev nqa ib feem ntawm cov sib tov nrog cov duav lossis cov cuab yeej sib xyaw.
• Cov pob zeb yuav tsum muaj cov ua ke ua ke uas tso cai rau nws kom yooj yim tso, molded, thiab ua tiav yam tsis tau swb dhau los lossis cais.

8. Kho raws li xav tau:

• Yog tias cov qhob qhuav dhau lawm, ntxiv cov dej me me thiab remix kom txog rau thaum qhov xav tau kev coj ua tau tiav.
• Yog tias cov qhob ntub yog ntub heev, ntxiv cov khoom xyaw qhuav ntxiv (xis mas, xuab zeb, lossis aggregate) los kho cov sib tov sib xyaw ua ke.

9. Txuas ntxiv sib xyaw:

• Muab cov pob zeb ua rau kom muaj peev xwm ua kom txhua yam kev sib xyaw ua ke ntawm cov khoom xyaw thiab kev ua kom ua kom muaj dej xis.
• Lub sijhawm sib xyaw tag nrho yuav nyob ntawm cov pob loj, sib xyaw qauv, thiab cov kev xav tau ntawm cov pob zeb ua kom sib xyaw.

10. Siv tam sim ntawd:

• Thaum sib xyaw ua ke, siv cov qhob kom tiv thaiv kev teeb tsa thaum ntxov thiab ua kom muaj kev tso cai kom zoo thiab kev sib sau ua ke.
• Zam txhob qeeb hauv nchuav lossis thauj cov pob zeb ua kom muaj qhov chaw xav tau los tswj kev ua haujlwm kom ua haujlwm thiab ua tiav kev ua kom muaj zog.

11. Huv Si Khoom Siv:

• Tom qab siv, ntxuav cov khoom xyaw huv, cov cuab yeej, thiab khoom siv kom tiv thaiv cov qhob qhob qhob buildup thiab kom lawv nyob hauv cov xwm txheej zoo rau kev siv hauv yav tom ntej.

Los ntawm ua raws li cov kauj ruam no thiab adhering rau kev sib xyaw ua ke, koj tuaj yeem ua tiav cov khoom sib xyaw kom zoo uas ua tau raws li cov qauv yam xav tau rau koj txoj haujlwm kev tsim kho.
