Limestone (calcium carbonate CaCO3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium.
This activity is most appropriate for students aged 14-16 to illustrate chemical reactions and useful materials made from rocks. Some of the simple chemical reactions of limestone (calcium carbonate, CaCO 3) and lime (calcium oxide, CaO).
Hydraulic lime is also called water lime. Hydraulic lime contains lime with silica or alumina and sets with exposure to water and can set under water. [14] Natural hydraulic lime (NHL) is made from a limestone which naturally contains some clay.
19 wrz 2024 · Limestone, sedimentary rock composed mainly of calcium carbonate, usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz.
