Calcite

Maryam Ghodrat, in SelfCompacting Concrete: Materials, Properties and Applications, 2020. Marble dust (MD) Marble is a crystalline, compact variety of metamorphosed limestone, consisting primarily of calcite (CaCO 3), dolomite (Ca Mg (CO 3) 2) or a combination of both minerals. Two types of byproducts are produced in marble processing. 30% of

Uses of Marble

Marble can also take a very high polish. Thus, it is also used in making sculptures. Construction Aggregate. Crushed marble is often used as construction aggregate and is used as fill. It has been found out that marble cleaves more readily than limestone due to the presence of calcite. Brightener, Filler, Pigment. Some marbles are extremely white.

Difference Between Limestone and Dolomite

Dec 03, 2013Limestone is soluble in weak acidic media generally and sometimes even in water. Depending on the pH value of water, temperature of water, and ion concentration, calcite may remain as a precipitate or dissolve. Therefore, limestone can only barely survive in water and, when in deep water bodies, it dissolves due to high water pressure.
