Kev sib dhos ua ke ntawm granite yog ib qho tseem ceeb hauv kev tsim kho thiab tsim ntau hom tshuab thiab khoom siv, suav nrog cov cuab yeej ua duab. Granite yog pob zeb ntuj uas ruaj khov heev thiab tiv taus kev hnav thiab rhuav, ua rau nws yog qhov kev xaiv nrov rau kev siv hauv kev lag luam. Txawm li cas los xij, txawm tias nws muaj ntau yam txiaj ntsig, kev sib dhos ua ke ntawm granite tuaj yeem ua rau muaj qee qhov tsis zoo uas yuav tsum tau kho kom ntseeg tau tias qhov zoo thiab kev sib xws ntawm cov khoom kawg.
Ib qho ntawm cov teeb meem tseem ceeb ntawm kev sib dhos granite yog nws qhov kev cuam tshuam rau kev warping lossis tawg. Qhov no yog qhov tseeb tshwj xeeb thaum lub granite raug rau kev hloov pauv ntawm qhov kub lossis av noo, vim tias cov xwm txheej no tuaj yeem ua rau lub pob zeb nthuav dav lossis cog lus. Yog tias lub granite tsis tau tuav lossis teeb tsa kom zoo, nws tuaj yeem tsim cov kab nrib pleb me me uas thaum kawg tuaj yeem ua rau muaj kev puas tsuaj loj dua dhau sijhawm. Txhawm rau tiv thaiv qhov no kom tsis txhob tshwm sim, cov chaw tsim khoom yuav tsum ua cov kev ntsuas los tswj hwm ib puag ncig thiab qhov kub thoob plaws hauv cov txheej txheem sib dhos.
Lwm qhov tsis zoo ntawm kev sib dhos granite yog nws qhov muaj peev xwm ua rau muaj qhov ntev sib txawv. Vim tias granite yog cov khoom siv ntuj, tuaj yeem muaj qhov sib txawv ntawm nws qhov ntev ntawm ib lub thaiv mus rau lwm qhov. Cov kev hloov pauv no tuaj yeem ua rau tsis sib xws hauv cov khoom kawg, uas tuaj yeem cuam tshuam tsis zoo rau nws cov kev ua tau zoo. Txhawm rau daws qhov teeb meem no, cov chaw tsim khoom yuav tsum ua tib zoo xaiv cov granite blocks thiab siv cov cuab yeej ntsuas thiab cov txheej txheem kom ntseeg tau tias txhua daim yog qhov loj me thiab txiav kom raug.
Txawm hais tias cov khoom siv granite sib dhos ruaj khov heev, nws kuj tseem yuav yooj yim hnav thiab rhuav dhau sijhawm. Qhov no tuaj yeem tshwm sim los ntawm ntau yam, suav nrog kev raug tshuaj lom neeg hnyav, kev siv ntau zaus, thiab kev laus dav dav. Qhov kev hnav thiab rhuav no tuaj yeem ua rau muaj kev puas tsuaj corrosive, khawb, lossis chipping, uas tuaj yeem cuam tshuam rau kev ua haujlwm tag nrho ntawm cov khoom siv. Txhawm rau tiv thaiv qhov no kom tsis txhob tshwm sim, cov chaw tsim khoom yuav tsum siv cov granite zoo uas tiv taus kev puas tsuaj thiab siv cov txheej txheem ntxuav thiab txij nkawm kom raug kom ntseeg tau tias nws siv tau ntev.
Lwm qhov tsis zoo ntawm kev sib dhos granite yog nws qhov hnyav. Granite yog ib yam khoom hnyav, uas tuaj yeem ua rau kev thauj mus los thiab kev teeb tsa nyuaj. Qhov no yog qhov tseeb tshwj xeeb rau cov khoom loj dua xws li cov rooj granite, uas tuaj yeem hnyav ntau tons. Txawm li cas los xij, cov chaw tsim khoom tuaj yeem txo qhov teeb meem no los ntawm kev siv cov tshuab thiab cov khoom siv tshwj xeeb uas tuaj yeem tswj qhov hnyav ntawm cov khoom no.
Hauv kev xaus lus, thaum lub rooj sib dhos granite yog qhov kev xaiv zoo thiab nrov rau cov cuab yeej ua duab, nws tuaj yeem ua rau muaj qee qhov teeb meem thiab qhov tsis zoo. Cov teeb meem no tuaj yeem suav nrog kev sib txhuam lossis tawg, qhov sib txawv ntawm qhov ntev, hnav thiab tsim kua muag, thiab qhov hnyav. Txawm li cas los xij, los ntawm kev siv cov kev ntsuas thiab cov txheej txheem tsim nyog, cov chaw tsim khoom tuaj yeem ua kom ntseeg tau tias lawv cov rooj sib dhos granite yog qhov zoo tshaj plaws thiab kev ua tau zoo, muab cov txiaj ntsig zoo tshaj plaws rau lawv cov neeg siv khoom.
