Granite tuaj yeem siv hauv tsev. Granite pob zeb muaj cov qauv compact, siab compressive zog, tsis tshua muaj dej nqus, siab deg hardness, zoo tshuaj stability, muaj zog durability, tab sis tsis zoo hluav taws kub. Txawm li cas los xij, nws raug pom zoo kom nyob ntawm qhov loj ntawm qhov chaw. Granite tuaj yeem tawg mus rau tib neeg lub cev, thiab kev raug kaw ntev ntev tuaj yeem ua rau lub hauv siab nruj thiab kiv taub hau. Thiab tus kheej, kuv tsis xav tias kho kom zoo nkauj granite yog sov heev thaum nws los txog hauv tsev. Feem ntau nws yog siv rau hauv cov tsev ua haujlwm thiab lwm qhov chaw. Qhov tseeb, cov lus hais tias granite muaj hluav taws xob tsis raug, thiab cov qauv tsim nyog yuav tsum yog "natural pob zeb muaj hluav taws xob." Txawm hais tias nws yog tib neeg tsim los yog ntuj pob zeb, nws muaj radionuclides, thiab Tuam Tshoj muaj cov qauv los ntsuas cov xov tooj cua no, feem ntau yog ntsuas cov xov tooj cua ntawm radium, thorium, thiab potassium.
Cov kev txwv rau radionuclides hauv cov khoom siv kho kom zoo nkauj, cov khoom siv pob zeb, tau muab faib ua peb pawg: A, B, C: Chav A yuav tsum muaj qhov cuam tshuam sab hauv qis dua lossis sib npaug rau 1.0, thiab qhov cuam tshuam sab nraud ntawm Tsawg dua lossis sib npaug li 1.3; Qhov ntsuas sab hauv ntawm cov khoom siv kho kom zoo nkauj hauv chav B yuav tsum tsawg dua lossis sib npaug rau 1.3, thiab qhov ntsuas pom sab nraud yuav tsum tsawg dua lossis sib npaug rau 1.9; Qhov cuam tshuam sab nraud ntawm Class C cov ntaub ntawv kho kom zoo nkauj yog tsawg dua lossis sib npaug rau 2.8.
Lub ntuj granite siv hauv cov khoom siv kho kom zoo nkauj hauv tsev yog tswj hwm los ntawm cov tuam haujlwm tseem ceeb los ntawm mining mus rau ntau lawm, thiab dab tsi tuaj yeem tau txais thiab nthuav tawm hauv kev ua lag luam ua tau raws li cov qauv hauv lub tebchaws. Yog li ntawd, tom qab hnov ib co lus xaiv, koj yuav tsum tsis txhob ntshai heev. Koj tuaj yeem sab laj nrog kev tiv thaiv ib puag ncig thiab kev tshuaj xyuas zoo.
