Coarse aggregates yog cov khoom loj dua 0.19 nti, tab sis feem ntau yog nyob nruab nrab ntawm 3/8 thiab 1.5 nti indiameter. Gravels yog feem ntau ntawm coarseaggregate siv hauv pob zeb nrog crushed pob zeb ua rau feem ntau ntawm cov seem.
Ntxiv mus, qhov loj ntawm coarse aggregates yog dab tsi?
Feem ntau, coarse aggregate qhov ntau thiab tsawg yog loj dua 4.75 hli (5 hli hauv British code), thaum zoo aggregates formthe seem hauv qab 4.75 mm. Qhov siab tshaj plaws qhov loj mus txog 40 mm isused rau ntxhib aggregate nyob rau hauv feem ntau daim ntawv thov, thaum rau loj concreting lub hom phiaj xws li dams, qhov ntau thiab tsawg tuaj yeem siv txog li 150 hli.
Tsis tas li ntawd, vim li cas cov coarse aggregates siv rau hauv pob zeb? Lawv muab lub zog sib zog thiab ntau rau pob zeb . Rau qhov zoo pob zeb sib tov, sib sau ua ke yuav tsum tau huv si, tawv, muaj zog hais tsis muaj absorbed chemicalsor txheej ntawm av nplaum thiab lwm yam ntaub ntawv zoo uas yuav ua rau deterioration ntawm pob zeb . • Aggregates muab faib rau hauv ob qho tib si ' ntxhib 'los yog 'zoo' pawg.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog qhov txawv ntawm cov nplua thiab ntxhib aggregates?
Fine aggregates yog me me muab tub lim cov ntaub ntawv hauv kev tsim kho. Coarse aggregates yog cov loj loj fillermaterials hauv kev tsim kho. Fine aggregates yog cov particlesthat hla 4.75 hli sieve thiab khaws cia ntawm 0.075 hli sieve. Thevoids nruab nrab tus ntxhib aggregate yog sau los ntawm zoo tag nrho.
Dab tsi yog hom aggregates?
Hom Aggregates
- Hom 1: Granite Aggregates. Qhov no yog qhov zoo tshaj plaws aggregate forhigh-qib pob zeb, thiab raws li nws los nyob rau hauv ntau yam ntxoov, likegrey, liab thiab liab, nws kuj yuav siv tau raws li ib tug decorative feature.
- Hom 1: Limestone Aggregates.
