Nyob zoo VS Coarse Aggregate
Cov lus zoo thiab ntxhib sib sau ua ke yog siv nrog cov ntaub ntawv uas siv los sib xyaw nrog pob zeb hauv kev tsim kho. Aggregate yog cov khoom sib xyaw uas pab ua ke cov pob zeb ua ke vim nws ntxiv zog thiab ntxiv dag zog rau pob zeb. Aggregate yog sib xyaw nrog cov cement los tsim cov pob zeb uas yog siv los nteg lub hauv paus ntawm txoj kev lossis txawm tias lub ru tsev hauv ib lub tsev. Ntau cov ntaub ntawv siv los tsim cov khoom sib xyaw xws li xuab zeb, gravel, pob zeb, pob zeb crushed, thiab qee zaum txawm tias khib nyiab slug los ntawm hlau thiab hlau kev lag luam. Aggregates yog dav faib ua nplua thiab ntxhib. Qhov sib txawv ntawm ob hom kev sib sau no yuav tau tham hauv kab lus no.
Cov khoom xyaw ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm pob zeb. Nyob rau hauv qis mus rau nruab nrab lub zog pob zeb, crushed pob zeb uas yog ntxhib tshwm sim los ntawm tus nqi qis vim nws pab ua kom lub ntim xav tau los sau lub hauv paus. Tab sis thaum qhov kev ua tau zoo ntawm cov pob zeb yuav tsum tau nyob qhov twg lub zog ntawm cov pob zeb yog ze rau lub zog ntawm cov aggregate, zoo aggregate yuav tsum tau kom tsis muaj zog nyob rau hauv cov qauv.
Nws yog ib qho tseem ceeb uas yuav tsum sib tov ob qho tib si zoo thiab ntxhib sib sau ua ke hauv cov pob zeb ua pob zeb sib sau ua ke tsis tuaj yeem npog thaj chaw saum npoo raws li cov khoom sib xyaw zoo. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov kev koom tes ntawm ntxhib aggregate nyob rau hauv npog thaj tsam saum npoo yog qis dua cov nplua aggregate. Raws li cov duab tau txiav txim siab, cov duab kheej kheej yog suav tias yog qhov zoo tshaj plaws kom ua tiav qhov ntim siab tshaj plaws ua raws li cov duab cubical thiab flaky.
Oversize aggregate tsim teeb meem hauv kev teeb tsa cov pob zeb ua kom yooj yim ntawm qhov chaw. Txawm hais tias mus rau ntxhib los yog nplua aggregate nws yuav tsum nco ntsoov tias yuav tsum tsis txhob muaj qhov sib txawv loj ntawm qhov loj ntawm cov khoom vim nws hampers ib qho kev ua tau zoo. Yuav kom muaj cov pob zeb uas ua tau zoo txaus, qhov loj me yuav tsum sib npaug li qhov ua tau txawm tias siv cov ntxhib los yog nplua aggregate. Nws yog qhov pom tseeb tias cov pob zeb pob zeb xav kom sib sau ua ke kom cov pob zeb tuaj yeem muab tso thiab compacted nrog kev siv zog me ntsis. Txhawm rau ua tiav lub hom phiaj no, txoj hauv kev zoo tshaj plaws yog mus rau cov khoom sib xyaw ua ke.
