Granite zog

Granite yog nws cov khoom ntawd, nws lub cev yam ntxwv xws li ua raws porosity/permeability: negligible lub cev allergic ntawm lub granite, rau 0.2% - 4% thermal stability: granite nrog thermal stability kub, nws yuav tsis hloov vim cov kev hloov hauv cov kub nraum zoov, granite, tsis yog vim nws cov kev kub ceev vim kub muaj kev hloov thiab kev pauv nyob rau hauv tej huab cua muaj pes tsawg leeg. Granite muaj ib tug kuj corrosion zog, ces nws yog lug siv rau lub cia ductility tshuaj corrosive yam: extension ntawm granite xim ntau yam 4.7x10-6-9.0x10-6 (inchxinch.): lub granite xim thiab tus hardness ntawm cov khoom siv no mas zoo ib yam: granite yog cov yam ntawm cov ntaub ntawv, tiam sis kuj vim nws cov hardness superior thiab nws yuav puas zoo heev kuj. Cov khoom xyaw: granite no mas muaj li ntawm quartz thiab orthoclase los yog microcline, thiab tus thawj granite yog li ntawm peb yam: quartz biotite feldspar. Los ntawm cov kev faib ua feem txhua tivthaiv thiab khoom siv, tiam sis feem ntau cov kev faib ua feem ntawm feldspar xim yog biotite quartz 10% - 60% 65% - 90% 10% - 15%
