Cov pob zeb granite yog los ntawm cov txheej marble hauv av. Tom qab ntau lab xyoo ntawm kev laus, lawv cov duab tseem ruaj khov heev, tshem tawm qhov kev pheej hmoo ntawm kev hloov pauv vim qhov kub thiab txias hloov pauv. Cov khoom siv granite no, xaiv ua tib zoo thiab raug kuaj xyuas lub cev zoo, muaj cov siv lead ua zoo thiab cov qauv tawv, muaj lub zog compressive ntawm 2290-3750 kg / cm² thiab qhov nyuaj ntawm 6-7 ntawm Mohs scale.
1. Feem ntau tsom mus rau qhov ruaj khov thiab yooj yim rau kev saib xyuas, cov pob zeb granite muaj cov qauv me me, qhov chaw du, tsis yooj yim hnav, thiab qhov roughness tsawg.
2. Tom qab lub sijhawm ntev ntawm kev laus ntuj, cov pob zeb granite tshem tawm cov kev ntxhov siab sab hauv, ua rau cov khoom ruaj khov, tsis yooj yim hloov pauv.
3. Lawv tiv taus cov kua qaub, alkalis, corrosion, thiab magnetism; lawv tiv taus dej noo thiab xeb, ua rau lawv yooj yim siv thiab tswj. Lawv kuj muaj cov coefficient nthuav dav qis thiab tsis tshua muaj kev cuam tshuam los ntawm qhov kub thiab txias.
4. Kev cuam tshuam lossis khawb rau ntawm qhov chaw ua haujlwm tsuas yog tsim cov qhov, tsis muaj cov kab lossis cov burrs, uas tsis muaj feem cuam tshuam rau qhov tseeb ntawm kev ntsuas.
5. Cov pob zeb granite yog ua los ntawm cov txheej marble hauv av. Tom qab ntau lab xyoo ntawm kev laus, lawv cov duab tseem ruaj khov heev, tshem tawm qhov kev pheej hmoo ntawm kev hloov pauv vim qhov kub thiab txias hloov pauv. Cov granite, xaiv zoo thiab kuaj xyuas zoo, muaj cov siv lead ua zoo thiab cov qauv tawv. Nws lub zog compressive ncav cuag 2290-3750 kg / cm², thiab nws qhov nyuaj ncav cuag 6-7 ntawm Mohs scale.
