Granite tau dhau los ua cov khoom siv dav hauv cov khoom siv ntsuas qhov tseeb vim nws qhov ruaj khov zoo heev, ruaj khov, tiv taus kev hnav thiab tiv taus corrosion. Txawm li cas los xij, qhov cuam tshuam rau ib puag ncig ntawm kev siv granite hauv cov khoom siv zoo li no yog ib qho kev txhawj xeeb. Kev tiv thaiv ib puag ncig ntawm granite hauv cov khoom siv ntsuas qhov tseeb muaj ntau yam uas yuav tsum tau xav txog.
Ua ntej, kev rho cov granite los siv rau hauv cov khoom siv ntsuas qhov tseeb muaj kev cuam tshuam loj heev rau ib puag ncig. Kev ua haujlwm khawb av tuaj yeem ua rau muaj kev puas tsuaj rau qhov chaw nyob, kev puas tsuaj ntawm av thiab kev ua qias tuaj ntawm dej. Txhawm rau daws qhov teeb meem no, cov chaw tsim khoom yuav tsum tau nrhiav cov granite los ntawm cov chaw khawb av uas ua raws li cov kev coj ua khawb av uas ruaj khov thiab muaj lub luag haujlwm. Qhov no suav nrog kev rov qab siv cov chaw khawb av, txo qis kev siv dej thiab lub zog, thiab txo cov pa phem ntawm cov pa phem.
Tsis tas li ntawd xwb, kev ua thiab tsim cov granite rau hauv cov cuab yeej ntsuas qhov tseeb muaj kev cuam tshuam rau ib puag ncig. Kev txiav, kev ua kom zoo nkauj thiab kev ua tiav ntawm granite ua rau muaj cov khoom pov tseg thiab kev siv hluav taws xob. Txhawm rau kom txo tau cov kev cuam tshuam no, cov chaw tsim khoom tuaj yeem siv cov txheej txheem tsim khoom zoo, siv cov granite rov ua dua tshiab, thiab nqis peev rau hauv cov thev naus laus zis uas txo kev siv hluav taws xob thiab kev tsim cov khib nyiab.
Tsis tas li ntawd xwb, kev pov tseg cov khoom siv ntsuas granite thaum kawg ntawm nws lub neej yog lwm qhov kev xav txog ib puag ncig. Txhawm rau kom txo qis lawv cov teeb meem ib puag ncig, cov chaw tsim khoom tuaj yeem tsim cov khoom siv rau kev rhuav tshem thiab rov ua dua tshiab, kom ntseeg tau tias cov khoom muaj nqis xws li granite tuaj yeem rov qab tau thiab rov siv dua. Kev pov tseg thiab rov ua dua tshiab ntawm cov khoom siv granite kom raug tuaj yeem pab txo qhov xav tau cov khoom siv raw tshiab thiab txo qhov hnyav ntawm cov peev txheej ntuj.
Zuag qhia tag nrho, kev tiv thaiv ib puag ncig ntawm granite hauv cov khoom siv ntsuas qhov tseeb yuav tsum muaj txoj hauv kev dav dav uas suav nrog kev nrhiav khoom zoo, kev tsim khoom ruaj khov thiab kev txiav txim siab thaum kawg ntawm lub neej. Los ntawm kev muab qhov tseem ceeb rau kev tiv thaiv ib puag ncig thoob plaws lub voj voog ntawm cov khoom siv granite, cov chaw tsim khoom tuaj yeem txo lawv qhov cuam tshuam rau ib puag ncig thiab pab txhawb rau kev lag luam ruaj khov dua. Tsis tas li ntawd, kev tshawb fawb thiab kev txhim kho txuas ntxiv tuaj yeem txheeb xyuas lwm cov ntaub ntawv uas muaj cov yam ntxwv zoo sib xws rau granite tab sis muaj qhov cuam tshuam tsawg dua rau ib puag ncig.
