Granite siv dav ua cov khoom siv rau cov khoom siv ua haujlwm kom raug hauv ntau yam lag luam, tshwj xeeb tshaj yog rau cov kab ncaj nraim uas ruaj khov thiab raug yog qhov tseem ceeb. Cia peb saib ze dua seb vim li cas granite yog cov khoom siv nyiam rau cov kab ncaj nraim.
Granite, uas yog ib hom pob zeb igneous uas ua los ntawm quartz, feldspar, thiab mica, muaj cov yam ntxwv tshwj xeeb uas ua rau nws yog cov khoom siv zoo tshaj plaws rau cov pob zeb linear. Ua ntej, granite muaj qhov nyuaj tshwj xeeb, thiab nws yuav luag tsis yooj yim khawb. Nws tsis yooj yim rau kev hnav thiab rhuav, uas ua rau nws zoo heev rau cov ntawv thov uas xav tau kev siv zog thiab siv ntev.
Qhov thib ob, granite muaj kev ruaj khov zoo heev, uas txhais tau tias nws tiv taus qhov kub thiab txias thiab kev hloov pauv vim dej noo. Nws kuj muaj qhov kub thiab txias tsawg heev, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau kev ruaj khov kub.
Qhov thib peb, granite lub zog thiab kev tawv nqaij zoo kawg nkaus yog cov yam ntxwv zoo heev rau kev tsim cov kab ncaj nraim. Nws muaj cov coefficient qis heev ntawm kev nthuav dav thermal, ua rau nws yog cov khoom siv zoo heev rau kev siv rau cov khoom ua haujlwm uas xav tau kev ua haujlwm siab, kev ruaj khov, thiab kev raug.
Qhov thib plaub, granite cov khoom siv tiv thaiv kev co zoo tshaj plaws yog qhov zoo tagnrho rau cov ntawv thov uas xav tau kev tiv thaiv kev co siab kom txo tau suab nrov thiab kev co. Nws yog ib qho tseem ceeb hauv kev ua kom raug ntawm cov kab sib txuas vim tias kev co tuaj yeem cuam tshuam qhov tseeb ntawm kev txav mus los thiab ua rau muaj cov teebmeem tsis xav tau.
Thaum kawg, granite tiv taus feem ntau cov kua qaub, alkalis, thiab tshuaj lom neeg, ua rau nws yog qhov kev xaiv zoo heev rau cov ntawv thov uas cuam tshuam nrog kev raug rau cov chaw acidic lossis alkaline.
Xaus lus, granite yog ib yam khoom zoo heev rau cov kab ncaj nraim vim nws qhov nyuaj tshwj xeeb, qhov ruaj khov ntawm qhov ntev, kev sib zog, cov khoom tiv thaiv kev co, thiab kev tiv thaiv corrosion. Nrog cov khoom no, granite ua kom cov khoom raug tseeb tseem ruaj khov thiab siv tau ntev, ua kom raug qhov zoo tshaj plaws, thiab txo qhov kev cuam tshuam lossis kev co uas yuav ua rau muaj qhov tsis raug.
