Ib yam li ntawd, hom pob zeb twg siv rau lub tsev?
Ntau yam ntawm peb hom pob zeb - sedimentary, igneous, thiab metamorphic - yog siv los ua cov pob zeb tsim. Sedimentary pob zeb muaj ntau yam sib txawv, sib txawv ntawm cov xim, kev ntxhib los mos, thiab muaj pes tsawg leeg.
Tom qab, lo lus nug yog, dab tsi pob zeb siv rau? Pob zeb yog siv rau ntau lub hom phiaj tab sis qee qhov ntawm lawv uas peb tuaj yeem pom hauv peb lub neej txhua hnub tau hais hauv qab no:
- Ua Cement (Limestone) (Sedimentary Origin)
- Sau ntawv (Chalk) (Sedimentary Origin)
- Khoom siv hauv tsev (Sandstone) (Sedimentary Origin)
- Bath Scrub (Pumice) (Igneous Origin)
- Pob zeb pob zeb (Granite) (Igneous Keeb Kwm)
Tsis tas li ntawd, pob zeb siv li cas hauv kev tsim kho?
Zoo tagnrho cov tsev thiab pej xeem cov qauv xav tau sedimentary pob zeb hauv lawv kev tsim kho . Cov cement, xuab zeb thiab gravel siv ua pob zeb, hlau ore rau steel, bauxite siv hauv kev ua aluminium, cib thiab pobzeb, txiav pob zeb siv rau ntsej muag loj cov tsev , thiab txawm asphalt rau txoj kev.
Dab tsi yog pob zeb siv rau hauv kev tsim kho?
Aggregates - pob zeb siv rau nws lub cev muaj zog - crushed thiab sorted rau hauv ntau qhov ntau thiab tsawg rau siv hauv pob zeb, coated nrog bitumen los ua asphalt lossis siv 'qhuav' raws li bulk sau kev tsim kho . Feem ntau siv nyob rau hauv txoj kev, pob zeb thiab cov khoom tsim.
