Granite tau ntev los lawm suav hais tias yog cov khoom siv zoo heev rau kev ua cov vaj huam sib luag saum npoo av, uas yog ib qho cuab yeej tseem ceeb hauv kev tsim khoom thiab kev tsim khoom. Cov yam ntxwv tshwj xeeb ntawm granite ua rau nws zoo tagnrho rau cov ntawv thov zoo li no, ua rau nws yog thawj qhov kev xaiv ntawm cov kws tshaj lij hauv ntau yam lag luam.
Ib qho ntawm cov laj thawj tseem ceeb uas ua rau granite tsim nyog ua ib lub slab saum npoo yog nws qhov ruaj khov. Granite yog ib lub pob zeb igneous uas tsim los ntawm magma txias thiab yog li ntawd muaj cov qauv ntom thiab sib xws. Qhov ntom no ua kom ntseeg tau tias cov slab saum npoo granite tsis yooj yim rau kev warping lossis deforming dhau sijhawm, tswj lawv qhov tiaj tus thiab raug. Qhov ruaj khov no yog qhov tseem ceeb rau kev ntsuas qhov tseeb, vim tias txawm tias qhov kev hloov pauv me me tuaj yeem ua rau muaj qhov yuam kev loj hauv cov txheej txheem tsim khoom.
Lwm qhov zoo ntawm granite yog nws qhov nyuaj. Nrog Mohs hardness scale ntawm kwv yees li 6 txog 7, granite yog khawb thiab abrasion resistant, ua rau nws yog ib qho kev xaiv zoo rau cov nto uas yuav tiv taus kev siv hnyav. Qhov kev ruaj khov no tsis yog tsuas yog ua rau lub neej ntawm lub phaj nto ntev dua, tab sis kuj ua kom ntseeg tau tias nws tseem ntseeg tau thiab muaj peev xwm ntsuas tau raug rau lub sijhawm ntev.
Granite kuj muaj kev ruaj khov zoo heev. Nws tuaj yeem tiv taus qhov kub hloov pauv yam tsis muaj kev nthuav dav lossis kev cog lus tseem ceeb, uas yog qhov tseem ceeb hauv cov chaw uas kev tswj kub tseem ceeb heev. Cov khoom no pab tswj kev ncaj ncees ntawm kev ntsuas vim tias kev hloov pauv kub tuaj yeem cuam tshuam rau qhov loj ntawm cov khoom siv ntsuas.
Tsis tas li ntawd xwb, granite yooj yim ntxuav thiab saib xyuas. Nws qhov chaw tsis muaj qhov dej tsis yooj yim rau kev pleev xim thiab yooj yim so, ua kom cov khib nyiab thiab cov khoom tsis huv tsis cuam tshuam rau kev ua haujlwm raug.
Zuag qhia tag nrho, kev sib xyaw ua ke ntawm kev ruaj khov, qhov tawv, kev tiv taus cua sov thiab kev yooj yim ntawm kev saib xyuas ua rau granite yog cov khoom siv zoo tshaj plaws rau cov slabs saum npoo av. Nws cov yam ntxwv tshwj xeeb tsis yog tsuas yog txhim kho qhov tseeb ntawm kev ntsuas, tab sis kuj ua rau kom muaj kev ua haujlwm zoo thiab kev ntseeg siab ntawm cov txheej txheem tsim khoom.
