Qhov sib txawv ntawm Fine thiab Coarse Aggregate

Aggregatesyog cov khoom tseem ceeb ntawm pob zeb.Lawv ua raws li cov khoom siv inert hauv pob zeb.Fine thiab coarse aggregate yog ob hom kev sib sau ua ke rau pob zeb.Raws li lub npe qhia, lawv yog qhov yooj yim cais nyob ntawm qhov ntau thiab tsawg ntawm cov khoom sib sau.

Dab tsi yog Aggregates?
Aggregates yog cov khoom tseem ceeb ntawm cov pob zeb uas muab lub cev rau cov pob zeb thiab tseem txo qis qis.Aggregates nyob 70 mus rau 80% ntawm tag nrho cov ntim ntawm pob zeb.Yog li, peb tuaj yeem hais tias ib tus yuav tsum paub meej txog qhov sib sau ua ke los kawm ntxiv txog kev ua vaj tse.
Fine Aggregate yog dab tsi??
Thaum cov aggregate sieved los ntawm ib tug 4.75 mm sieve, lub aggregate dhau los ntawm nws hu ua zoo aggregate.Cov xuab zeb ntuj feem ntau yog siv los ua cov sib sau ua ke zoo, cov av nplaum thiab av nplaum kuj tuaj nyob rau hauv pawg no.

Coarse Aggregate yog dab tsi??
Thaum cov aggregate sieved los ntawm ib tug 4.75 mm sieve, lub aggregate khaws cia yog hu ua coarse aggregate.Pob zeb, cobble thiab pob zeb tuaj nyob rau hauv pawg no.Qhov loj tshaj qhov sib sau ua ke siv yuav yog nyob ntawm qee qhov xwm txheej.Feem ntau, 40 mm loj aggregate siv rau ib txwm muaj zog thiab 20mm loj yog siv rau siab zog pob zeb.

Qhov sib txawv ntawm Fine thiab Coarse Aggregate
Kev sib xyaw ua ke zoo thiab ntxhib muaj qee qhov sib txawv loj.Qhov chaw ntawm qhov sib txawv tseem ceeb ntawm qhov tob thiab qhov tob tob yog txhais, qhov loj ntawm cov khoom, cov khoom siv, qhov chaw, thaj chaw saum npoo, kev ua haujlwm hauv pob zeb, siv, thiab lwm yam.
