Vim nws ruaj khov thiab muaj zog, granite yog qhov kev xaiv nrov rau cov hauv paus rau cov tshuab hnyav thiab cov khoom siv. Nws paub txog nws lub peev xwm los tiv taus cov khoom hnyav yam tsis muaj kev cuam tshuam qhov tseeb, ua rau nws yog cov khoom siv zoo tagnrho rau cov ntawv thov uas xav tau kev ua kom raug thiab ruaj khov.
Cov yam ntxwv ntuj ntawm granite ua rau nws yog qhov kev xaiv zoo heev rau cov khoom siv hauv pem teb. Nws qhov ceev ceev thiab porosity tsawg ua rau nws tsis yooj yim hnav, ua kom nws tuaj yeem tiv taus cov khoom hnyav yam tsis muaj kev cuam tshuam rau nws cov qauv. Qhov no txhais tau tias cov khoom siv thiab cov tshuab uas tau teeb tsa rau ntawm cov hauv paus granite tseem khaws lawv qhov tseeb thiab qhov tseeb txawm tias nyob rau hauv cov xwm txheej nyuaj tshaj plaws.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv granite ua lub substrate yog nws qhov ruaj khov. Cov khoom siv tsis yog tsuas yog muaj zog xwb, tab sis kuj tiv taus kev co thiab kev hloov pauv, uas yog qhov tseem ceeb rau kev tswj hwm qhov tseeb ntawm cov khoom siv precision. Qhov kev ruaj khov no ua kom ntseeg tau tias cov khoom siv tseem nyob hauv qhov chaw thiab ua haujlwm tas li txawm tias raug cov khoom hnyav lossis lub zog sab nraud.
Ntxiv rau nws lub zog thiab kev ruaj khov, granite tseem tiv taus qhov kub thiab txias thiab xeb, ua rau nws haum rau ntau yam kev lag luam thiab kev tsim khoom. Qhov no txhais tau tias lub hauv paus tswj nws cov qauv kev ruaj khov thiab qhov tseeb dhau sijhawm, txawm tias nyob rau hauv ib puag ncig hnyav.
Thaum xav txog seb lub hauv paus granite puas tuaj yeem tiv taus cov khoom hnyav yam tsis muaj kev cuam tshuam qhov tseeb, nws yog ib qho tseem ceeb uas yuav tsum xav txog cov kev cai tshwj xeeb ntawm daim ntawv thov. Cov yam xws li qhov hnyav thiab kev faib tawm ntawm cov khoom thauj thiab kev tsim thiab kev tsim kho ntawm lub hauv paus yuav ua lub luag haujlwm hauv kev txiav txim siab nws cov kev ua tau zoo.
Hauv kev xaus lus, granite yog cov khoom siv ruaj khov thiab ruaj khov uas tuaj yeem tiv taus cov khoom hnyav yam tsis muaj kev cuam tshuam qhov tseeb. Nws cov yam ntxwv ntuj tsim ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau kev ua kom raug thiab ruaj khov, ua kom cov khoom siv thiab cov tshuab ua haujlwm tas li thiab raug txawm tias nyob rau hauv qhov xwm txheej nyuaj tshaj plaws.
