Hom Thiab Tsim
Limestone yog lub pob zeb sedimentary uas tau tshwm sim los ntawm sedimentation. Limestone, uas muaj 50% calcium carbonate, yog tsim nyob rau hauv lub ntiaj teb nto los ntawm interacting nrog ntau yam organic hais. Aragonite, magnesium, thiab calcite kuj muaj.
Granite yog tsim nyob rau hauv qab lub ntiaj teb nto li magma los ntawm ib tug volcanic eruption txias, uas yuav siv sij hawm ntev piv rau lwm yam igneous pob zeb. Nws yog tsim los ntawm plagioclase thiab feldspar thiab yog quartz-based
Kev ua haujlwm
Limestone yog lub pob zeb ruaj khov thiab yooj yim-rau-txiav siv los tsim monuments thiab vaj tse. Hlau yog muab rho tawm los ntawm nws cov ore thiab siv los ua cov cement. Yog li ntawd, feem ntau ntawm txoj kev yog tsim nrog Limestone. Lawv kuj tau siv hauv kev lag luam tshuaj los ua cov khoom siv kho mob thiab tshuaj pleev ib ce.
Granite kuj tau ua hauj lwm hauv kev tsim vaj tse thiab sculpting ntawm monuments.
Nws yog Hard Thiab Grainy
Lawv tuaj yeem tsim ua ntau yam duab ntawm slabs, pem teb vuas, thiab countertops. Nws yog siv rau ob qho tib si sab hauv thiab sab nrauv. Nws ntxiv qhov sib txawv, kho kom zoo, thiab elegance rau sab hauv.
Qhov tshwm sim
Limestone tshwm daj los yog xim av vim yog hlau oxide, whereas carbon tshwm grey, dub, los yog xiav vim carbon.
Txawm li cas los xij, Limestone cov xim tiag tiag yog dawb, tab sis cov khoom sib txawv ua rau nws pom nrog lwm cov xim. Yog li ntawd, Limestone feem ntau ntxhib thiab banded. Granite xim yog tshwm sim los ntawm nws cov tshuaj muaj pes tsawg leeg.
