Dab tsi yog Crushed Stone Aggregate?
Crushed pob zeb aggregateyog cov khoom siv tsim los ntawm kev sib tsoo cov pob zeb loj loj -xws li granite, limestone, basalt, lossis gravel- rau hauv me me, angular fragments. Cov khoom no tau ua tiav los ntawm kev sib tsoo, kev tshuaj xyuas, thiab kev muab qhab nia kom tau raws li qhov loj me thiab kev ua tau zoo rau kev siv hauv kev tsim kho thiab kev tsim kho vaj tse.
Yuav Ua Li Cas Crushed Stone Aggregate Yog Tsim
Cov txheej txheem ntau lawm feem ntau suav nrog ntau theem:
- Kev rho tawm- Cov pob zeb nyoos yog muab rho tawm los ntawm quarries.
- Thawj Crushing- Cov pob zeb loj raug txo kom tsawg dua siv lub puab tsaig crushers.
- Secondary thiab Tertiary Crushing- Kev txo qhov loj ntxiv siv lub khob hliav qab lossis cuam tshuam crushers.
- Kev tshuaj ntsuam thiab muab qhab nia- Cov khoom yog txheeb rau hauv ntau qhov sib txawv.
- Ntxuav (yog tias xav tau)- Tshem tawm cov plua plav, av nplaum, lossis impurities.
Qhov tshwm sim yog ntau qhov sib sau ua ke tsim nyog rau kev siv sib txawv.
Common Sizes of Crushed Stone Aggregate
Crushed pob zeb muaj nyob rau hauv ntau qhov ntau thiab tsawg nyob ntawm qhov project xav tau:
- 0-5 hli (pob zeb hmoov av / nplua)- Siv rau hauv txaj, paving, thiab muab tub lim
- 5-10 hli- Kev sib xyaw ua ke thiab tso dej
- 5-20 hli- Kev tsim kho dav dav thiab kev ua vaj tse pob zeb
- 5-30 hli- Txoj kev hauv paus thiab txheej txheej
Cov yam ntxwv tseem ceeb
Crushed pob zeb aggregate muaj ob peb yam tseem ceeb:
- Angular puab- Muab kev sib cuam tshuam thiab ruaj khov
- Siab zog- Haum rau kev thauj khoom - cov ntawv thov kev coj tus kheej
- Cov dej ntws zoo- Tshwj xeeb tshaj yog nyob rau hauv qhov ntau thiab tsawg
- Durability-Resistant rau hnav thiab ib puag ncig tej yam kev mob
Cov yam ntxwv no ua rau nws tseem ceeb rau kev siv vaj tse thiab kev tsim vaj tsev.
Cov ntawv thov tseem ceeb
Crushed pob zeb aggregate yog dav siv nyob rau hauv:
1. Kev tsim khoom ua vaj tse
Ua raws li cov khoom tseem ceeb hauv pob zeb, muab lub zog thiab ntim.
2. Kev tsim kho txoj kev
Siv rau sub- puag, puag txheej, thiab asphalt sib tov.
3. Railway Ballast
Txhawb txoj kev tsheb ciav hlau thiab ua kom cov dej ntws zoo.
4. Cov kab dej ntws
Tso cai rau dej ntws los ntawm tsis muaj av yaig.
5. Landscaping thiab Paving
Siv rau hauv txoj kev, tsav tsheb, thiab kho kom zoo nkauj hauv av npog.
Crushed Stone vs Natural Gravel
- Pob zeb crushed: Angular, zoo interlocking, siab zog
- Ntuj pob zeb: Rounded, smoother, tsis ruaj khov nyob rau hauv load
Rau cov qauv siv, crushed pob zeb feem ntau nyiam.
Xaus
Crushed pob zeb sib sau ua ke yog cov khoom siv tseem ceeb hauv kev tsim kho niaj hnub, muaj nuj nqis rau nws lub zog, kev siv ntau yam, thiab ntau yam kev siv. Los ntawm kev xaiv qhov loj me thiab cov khoom siv tsim nyog, cov neeg cog lus thiab cov kws tsim khoom tuaj yeem ua kom pom kev ua haujlwm zoo hauv cov haujlwm xws li kev tsim khoom ua vaj tse mus rau loj - kev tsim kho vaj tse.
