Yuav ua li cas txhawm rau txhim kho kev ua haujlwm ntawm pob zeb
- Npaj dej/cement ratio.
- Nyob qhov loj ntawm cov aggregate.
- Siv zoo sib npaug thiab du sib sau ua ke hloov tsis zoo.
- Nyob rau lub sijhawm sib tov.
- Nco qhov kub thiab txias.
- Siv tsis yog ntxeem tau thiab saturated aggregate.
- Nrog ntxiv cov huab cua nkag mus.
Qhov tseem ceeb tshaj plaws hauv kev ua haujlwm ntawm pob zeb yog dab tsi?
dej ntsiab lus Nws yog qhov tseem ceeb tshaj plaws ntawm kev ua haujlwm. Kev ua haujlwm nce ntxiv nrog qhov nce ntawm cov ntsiab lus dej (ntsuas hauv kg lossis liter ib cubic meter ntawm pob zeb). Peb tuaj yeem nthuav qhia qhov kev sib raug zoo ntawm cov dej-cement piv.
Kev ua haujlwm ntawm pob zeb yog dab tsi?
Kev Ua Haujlwm ntawm Pob Zeb yog dab tsi? Kev ua haujlwm ntawm pob zeb yogdav thiab cov ntsiab lus piav qhia yooj yim npaum li cas cov pob zeb sib xyaw yooj yim tuaj yeem sib xyaw, muab tso, sib sau ua ke, thiab ua tiav nrog tsawg kawg poob ntawm homogeneity.
Yuav ua li cas yog siv rau kev ua haujlwm ntawm pob zeb?
Slump Test
slump test or slump cone test yog qhov kev sim ntau tshaj plaws rau kev ua haujlwm ntawm cov khoom sib xyaw tshiab pob zeb uas tuaj yeem ua tau ntawm qhov chaw ua haujlwm / chaw ua haujlwm lossis hauv chav kuaj.
Qhov kev xeem twg yog siv rau kev ua haujlwm qis?
Kev ntsuas kev sib cog lus yog tsim los siv rau hauv chav kuaj tab sis nws kuj tuaj yeem siv rau hauv thaj teb. Nws yog qhov tseeb dua thiab rhiab dua li qhov kev ntsuas slump thiab tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau kev sib xyaw ua ke ntawm kev ua haujlwm tsawg heev thiab feem ntau siv thaum pob zeb yuav tsum tau compacted los ntawm kev co.
