- Chalk - Dawb Cliffs ntawm Dover. Lub npe nrov Dawb Cliffs ntawm Dover muaj chalk, a hom limestone .
- Coral Reef Limestone .
- Tsiaj Plhaub Limestone .
- Limestone Ntau yam - Travertine.
- Dub Limestone Pob zeb.
Kuj tseem paub yog, limestone siv rau dab tsi?
Nws yog cov khoom siv raw rau kev tsim cov kua qaub (calcium oxide), slaked txiv qaub (calcium hydroxide), cement thiab mortar. Pulverized limestone yog siv li ib qho av txias rau neutralize acidic xau (ua liaj ua teb txiv qaub). Yog crushed rau siv li aggregate - lub hauv paus ruaj khov rau ntau txoj kev nrog rau hauv asphalt pob zeb.
Tsis tas li ntawd, yog limestone sedimentary pob zeb lossis metamorphic? Limestone yog txhais los ntawm ob lub ntsiab lus: nws yog pob zeb sedimentary (1) thiab nws yog tsim los ntawm calcium carbonate (2). Muaj lwm cov pob zeb uas muaj cov calcium carbonate. Carbonatite yog hom tsis tshua muaj igneous pob zeb thiab marble yog ib lub pob zeb metamorphic.
Yog li ntawd, limestone tsim li cas?
Limestone tsim nyob rau hauv ob txoj kev. Nws tuaj yeem yog tsim nrog kev pab ntawm cov kab mob nyob thiab los ntawm evaporation. Cov kab mob hauv dej hiav txwv xws li oysters, clams, mussels thiab coral siv calcium carbonate (CaCO3) pom hauv dej hiav txwv los tsim lawv cov plhaub thiab pob txha.
Vim li cas limestone siv hauv cement?
Cov limestone ua raws li cov noob siv lead ua rau lub cement , zoo dua faib cov tshuaj tiv thaiv cov khoom thiab ua kom cov reactivity ntawm cov cement . Raws li ib txwm muaj unhydrated cement hauv pob zeb , qhov kev hloov pauv no yuav tsis muaj qhov ntsuas tau tiag tiag ntawm qhov siv ntawm ya tshauv.
