Limestone siv hauv tsev li cas?
Limestone yog pob zeb sedimentary uas tau tsim nyob rau hauv dej hiav txwv, dej thiab pas dej ntau lab xyoo. Cov khoom siv ntuj no yog dav siv rau sab hauv thiab sab nrauv cladding, thiab feem ntau muaj cov fossilized fragments los yog ribbons ntawm flora thiab fauna.
Kev tsim kho kev lag luam siv limestone rau cov phab ntsa thiab cov plag tsev ntawm cov tsev. Los ntawm ancient Egyptian pyramids mus rau niaj hnub vaj tse, lub ntuj pob zeb no muaj zog, ruaj thiab resistant rau corrosion. Lawv tau txais txiaj ntsig zoo rau lawv cov kev ua tsis taus pa thiab kub ua haujlwm. Qhov tseeb, cov khoom zoo ntawm limestone cia qhov ntom ntom kom nws tuaj yeem kav ntev mus rau ntau pua xyoo. Nws yog siv nyob rau hauv niaj hnub thiab tsoos vaj tse rau vaj tse thiab kev lag luam daim ntaub ntawv:
1. Cov Vuas: Cov pobzeb limestone yog siv rau ntau yam kev siv xws li phab ntsa sab nrauv, sab hauv thiab sab nrauv phab ntsa, sab hauv thiab sab nrauv, lub vaj, pas dej da dej, pavements thiab taug kev. Lub pob zeb no tuaj yeem ntsia tau rau hauv chav ua noj, chav dej lossis qhov cub. Limestone yog lub pob zeb tsaus nti carbonate nrog cov khoom zoo heev thiab dolomite formations uas tuaj yeem ua rau txhua qhov loj txog 240x120cm. Standard hom yog 60x30cm thiab 60x40cm nrog thicknesses los ntawm 1.5 mus rau 3cm.
2. Panels: Limestone tuaj yeem siv rau cov vaj huam sib luag ntuj, rau phab ntsa. Nws tuaj yeem siv rau ob qho tib si sab hauv thiab sab nrauv cladding ua tsaug rau nws cov cuab yeej ua ke uas tuaj yeem ntsia tau rau ntawm qhov chaw tshaj li ob meters.
Limestone yog ib lub pob zeb uas muaj txiaj ntsig zoo hauv ob qho tib si ib txwm thiab niaj hnub ua haujlwm. Cov khoom siv ntuj no ntxiv kev zoo nkauj rau ntau lub tsev vim nws muaj ntau yam kev ua tiav, xws li polished lossis txhuam. Kev ua tiav rau lub pob zeb tuaj yeem hloov xim, ua kom muaj xim tsaus lossis nplua nuj xim. Nws tuaj yeem ua tiav lwm yam khoom siv hauv tsev thiab tuaj yeem siv rau hauv lwm cov ntaub ntawv zoo nkauj heev.
