Granite yog ib hom pob zeb uas tawv, ruaj khov, thiab siv dav hauv kev tsim kho thiab kev siv hauv kev lag luam. Nws feem ntau siv los ua cov khoom siv tshuab vim nws lub zog thiab kev ywj pheej. Txawm li cas los xij, txawm tias nws muaj cov yam ntxwv zoo tshaj plaws, cov khoom siv tshuab granite tuaj yeem muaj qhov tsis zoo uas cuam tshuam rau lawv txoj haujlwm. Hauv tsab xov xwm no, peb yuav tham txog qhov tsis zoo ntawm cov khoom siv tshuab granite kom ntxaws.
Ib qho ntawm cov teeb meem feem ntau ntawm cov khoom siv granite yog cov kab nrib pleb. Cov kab nrib pleb tshwm sim thaum qhov kev ntxhov siab tso rau ntawm qhov khoom tshaj nws lub zog. Qhov no tuaj yeem tshwm sim thaum lub sijhawm tsim khoom lossis siv. Yog tias qhov kab nrib pleb me me, nws yuav tsis cuam tshuam rau kev ua haujlwm ntawm qhov khoom siv tshuab. Txawm li cas los xij, cov kab nrib pleb loj dua tuaj yeem ua rau cov khoom ua tsis tiav tag nrho, ua rau muaj kev kho lossis hloov pauv kim.
Lwm qhov tsis zoo uas tuaj yeem tshwm sim hauv cov khoom siv granite yog warping. Warping tshwm sim thaum ib feem raug rau qhov kub siab, ua rau nws nthuav dav tsis sib npaug. Qhov no tuaj yeem ua rau ib feem ua distorted, uas tuaj yeem cuam tshuam rau nws txoj haujlwm. Nws yog ib qho tseem ceeb kom ntseeg tau tias cov khoom granite yog ua los ntawm cov ntaub ntawv zoo thiab raug tsim kom zoo kom tiv thaiv warping.
Cov khoom siv hauv tshuab granite kuj tseem muaj qhov tsis zoo xws li cov qhov cua thiab cov qhov khoob. Cov qhov tsis zoo no tshwm sim thaum lub sijhawm tsim khoom thaum huab cua raug kaw hauv granite. Yog li ntawd, qhov khoom yuav tsis muaj zog li nws yuav tsum tau ua, thiab nws yuav tsis ua haujlwm zoo. Nws yog ib qho tseem ceeb kom ntseeg tau tias cov khoom granite raug tsim los ntawm kev siv cov ntaub ntawv zoo thiab raug tshuaj xyuas kom zoo kom tiv thaiv cov qhov cua thiab cov qhov khoob.
Ntxiv rau qhov tawg, warping, thiab cov hnab cua, cov khoom siv granite tshuab kuj tseem tuaj yeem muaj qhov tsis zoo xws li qhov roughness ntawm qhov chaw thiab qhov tsis sib xws. Qhov roughness ntawm qhov chaw tuaj yeem tshwm sim los ntawm cov txheej txheem tsim khoom tsis raug, ua rau qhov chaw ntxhib lossis tsis sib xws. Qhov no tuaj yeem cuam tshuam rau kev ua haujlwm lossis kev ntseeg siab ntawm qhov chaw. Nws yog ib qho tseem ceeb kom ntseeg tau tias cov txheej txheem tsim khoom raug saib xyuas kom zoo kom tsim cov khoom nrog qhov du thiab txawm tias qhov chaw.
Lwm qhov tsis zoo uas tuaj yeem cuam tshuam rau cov khoom siv granite yog chipping. Qhov no tuaj yeem tshwm sim thaum lub sijhawm tsim khoom lossis vim yog kev hnav thiab tsim kua muag. Chipping tuaj yeem cuam tshuam rau kev ua haujlwm ntawm qhov khoom thiab tuaj yeem ua rau muaj kev puas tsuaj ntxiv yog tias tsis kho tam sim ntawd.
Xaus lus, cov khoom siv tshuab granite muaj zog thiab ruaj khov tab sis tuaj yeem muaj qhov tsis zoo uas cuam tshuam rau lawv qhov kev ua tau zoo. Nws yog ib qho tseem ceeb kom ntseeg tau tias cov khoom siv tau ua los ntawm cov khoom siv zoo thiab raug tsim kom zoo kom tiv thaiv cov qhov tsis zoo xws li tawg, warping, cua hnab thiab voids, qhov chaw roughness thiab tsis sib xws, thiab chipping. Los ntawm kev ua cov kev ceev faj no, peb tuaj yeem ua kom ntseeg tau tias cov khoom siv tshuab granite muaj kev ntseeg siab thiab ua haujlwm tau zoo.
