Granite yog ib yam khoom siv uas siv ntau hauv cov khoom siv ntsuas qhov tseeb vim nws muaj ntau yam zoo. Nws cov yam ntxwv tshwj xeeb ua rau nws zoo tagnrho rau kev ua kom raug thiab kev ntseeg tau hauv ntau yam kev siv hauv kev lag luam thiab chaw kuaj mob.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm granite hauv cov khoom siv ntsuas qhov tseeb yog nws qhov ruaj khov thiab rigidity tshwj xeeb. Granite muaj cov coefficient qis ntawm thermal expansion, uas txhais tau tias nws tsis tshua muaj peev xwm nthuav dav lossis cog lus nrog kev hloov pauv ntawm qhov kub thiab txias. Qhov kev ruaj khov no ua kom ntseeg tau tias qhov loj ntawm cov khoom siv ntsuas tseem sib xws txawm tias nyob rau hauv qhov xwm txheej ib puag ncig hloov pauv, uas yog qhov tseem ceeb rau kev ntsuas qhov tseeb.
Tsis tas li ntawd xwb, granite muaj cov khoom zoo heev uas ua rau nws tsis co, uas txhais tau tias nws nqus tau cov kev co thiab txo qhov cuam tshuam ntawm cov khoom siv ntsuas sab nraud. Qhov no tseem ceeb heev rau kev siv qhov tseeb, vim tias txawm tias qhov kev co me me lossis kev txav mus los kuj tuaj yeem cuam tshuam rau qhov tseeb ntawm kev ntsuas. Cov khoom zoo ntawm granite pab tswj kom muaj ib puag ncig ruaj khov thiab tswj tau rau kev ntsuas qhov tseeb.
Tsis tas li ntawd xwb, granite kuj paub txog nws qhov nyuaj thiab tsis yooj yim hnav. Qhov no ua rau nws ruaj khov heev thiab muaj peev xwm tiv taus kev siv ntau yam yam tsis lwj lossis hloov pauv raws sijhawm. Qhov nyuaj ntawm granite kuj pab txhawb rau nws lub peev xwm los tswj kom qhov chaw tiaj tus thiab du, uas yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm cov khoom siv ntsuas qhov tseeb.
Ntxiv rau nws cov khoom siv kho tshuab, granite tiv taus corrosion thiab tshuaj lom neeg puas tsuaj, ua rau nws tsim nyog siv rau hauv ntau yam kev lag luam thiab chaw kuaj mob uas xav tau kev raug cov tshuaj hnyav.
Kev ruaj khov ntuj, cov khoom ua kom noo noo, kev ruaj khov thiab kev tiv taus cov yam ntxwv ib puag ncig ua rau granite yog qhov kev xaiv zoo heev rau cov khoom siv ntsuas qhov tseeb. Nws siv rau hauv cov ntawv thov xws li cov tshuab ntsuas sib koom ua ke, cov theem thiab cov khoom sib piv kho qhov muag tau ua pov thawj nws qhov kev ntseeg siab thiab kev ua haujlwm zoo hauv kev ua kom muaj kev ntsuas raug thiab sib xws.
Hauv kev xaus, granite qhov zoo hauv cov khoom siv ntsuas qhov tseeb ua rau nws yog cov khoom siv xaiv rau cov lag luam uas xav tau kev ntsuas siab thiab kev ntseeg siab. Nws qhov kev sib xyaw ua ke ntawm cov khoom ua rau nws yog ib qho tseem ceeb hauv kev tsim thiab tsim cov cuab yeej ntsuas qhov tseeb, pab txhim kho qhov zoo thiab qhov tseeb ntawm ntau yam kev tsim khoom thiab cov txheej txheem kev tshawb fawb.
