Hom thiab qhov zoo ntawm cov khoom siv granite siv ua lub hauv paus rau lub tshuab ntsuas sib koom ua ke (CMM) yog qhov tseem ceeb rau nws txoj kev ruaj khov mus sij hawm ntev thiab kev khaws cia qhov tseeb. Granite yog ib qho kev xaiv khoom siv nrov vim nws cov khoom zoo heev xws li kev ruaj khov siab, kev nthuav dav thermal tsawg, thiab kev tiv thaiv kev hnav thiab xeb. Hauv tsab xov xwm no, peb yuav tshawb nrhiav seb ntau hom khoom siv granite tuaj yeem cuam tshuam li cas rau kev ruaj khov thiab qhov tseeb ntawm CMM.
Ua ntej, nws yog ib qho tseem ceeb kom nkag siab tias tsis yog txhua yam khoom siv granite zoo ib yam. Granite tuaj yeem sib txawv ntawm nws cov khoom siv lub cev thiab tshuaj lom neeg nyob ntawm qhov chaw uas nws tau los ntawm, qib, thiab cov txheej txheem tsim khoom. Qhov zoo ntawm cov khoom siv granite siv yuav txiav txim siab qhov ruaj khov thiab qhov tseeb ntawm CMM, uas yog qhov tseem ceeb rau kev ua haujlwm raug thiab kev tsim khoom.
Ib qho tseem ceeb uas yuav tsum xav txog yog qib ntawm cov quartz hauv granite. Quartz yog ib qho mineral uas yog lub luag haujlwm rau qhov nyuaj thiab ruaj khov ntawm granite. Cov granite zoo yuav tsum muaj tsawg kawg yog 20% quartz cov ntsiab lus kom ntseeg tau tias cov khoom siv ruaj khov thiab tuaj yeem tiv taus qhov hnyav thiab kev co ntawm CMM. Quartz kuj muab kev ruaj khov ntawm qhov ntev, uas yog qhov tsim nyog rau kev ntsuas qhov tseeb.
Lwm yam uas yuav tsum xav txog yog qhov porosity ntawm cov khoom siv granite. Cov granite uas muaj qhov porous tuaj yeem nqus cov dej noo thiab cov tshuaj lom neeg, uas tuaj yeem ua rau xeb thiab deformation ntawm lub hauv paus. Cov granite zoo yuav tsum muaj qhov porosity qis, ua rau nws tsis tuaj yeem nkag mus rau hauv dej thiab cov tshuaj lom neeg. Qhov no ua rau kev ruaj khov thiab qhov tseeb ntawm CMM zoo dua qub dhau sijhawm.
Qhov ua tiav ntawm lub hauv paus granite kuj tseem ceeb heev. Lub hauv paus CMM yuav tsum muaj qhov chaw tiav zoo kom muaj kev ruaj khov thiab raug ntawm lub tshuab. Yog tias qhov tiav tsis zoo, lub hauv paus tuaj yeem muaj qhov, khawb, thiab lwm yam tsis zoo ntawm qhov chaw uas tuaj yeem ua rau CMM tsis ruaj khov.
Xaus lus, qhov zoo ntawm cov khoom siv granite siv rau hauv CMM ua lub luag haujlwm tseem ceeb hauv nws txoj kev ruaj khov mus sij hawm ntev thiab kev khaws cia qhov tseeb. Cov granite zoo nrog cov ntsiab lus quartz tsim nyog, porosity tsawg, thiab qhov tiav zoo yuav muab qhov ruaj khov thiab qhov tseeb zoo tshaj plaws rau kev ntsuas daim ntawv thov. Kev xaiv tus neeg muag khoom uas muaj npe nrov uas siv cov granite zoo los tsim lawv cov tshuab ntsuas yuav ua kom CMM siv tau ntev thiab kev ntsuas qhov tseeb tas li.
