Lub ntsiab Cheebtsam ntawm cov pob zeb sab nraum zoov

Lub ntsiab Cheebtsam ntawm cov pob zeb sab nraum zoov muaj xws li granite, marble thiab limestone.

Zeb
Granite yog lub pob zeb tsis zoo tsuas yog tsim ntawm Quartz, Feldspar thiab MICA. Nws muaj pes tsawg leeg yog silicon dioxide, cov nyiaj txiag rau txog 60% {8%, Feldspar cov ntsiab lus yog 40%, thiab Quartz cov ntsiab lus yog 20% ​​rau 40%. Granite yog qhov nyuaj, hnav - tiv taus, muaj zog hauv compressive, nplua nuj hauv grey, nrog grey, xim daj thiab lwm yam kev xaiv.

Zeb
Marble yog metamorphosed los ntawm cov limestone, thiab nws lub ntsiab tseem yog calcium carbonate, suav rau ntau tshaj 50%. Nws tseem muaj cov pa roj carbonÃ, calcium oxide, manganese oxide thiab silicon dioxide. Marble muaj cov nyhuv zoo nkauj, tab sis nws lub hardness yog qis dua li cov granite, thiab nws cov coj tsis kam yog qhov tsis zoo me ntsis. Marble muaj cov qauv zoo nkauj thiab feem ntau yog siv rau kev pavement hauv qhov chaw siab, xws li cov chaw toj roob hauv pes hauv chaw ua si thiab cov chaw nyob hauv thaj chaw villa.

Zeb
Limestone feem ntau yog suav nrog calcite, limestine, Serestine thiab dolomentine, thiab nws lub ntsiab yog calcium carbonate. Limestone yog mos thiab yooj yim rau cov txheej txheem thiab txua ntoo, thiab feem ntau yog siv rau kho kom zoo nkauj thiab duab puab sab hauv.
