Dolomite is a double carbonate of calcium and magnesium and it exhibits a granular structure. It has high natural whiteness and its noted for their ease of dispersion. Its use improves properties such as wheatherability, reduces shrinkage, fissure development and water absorption .
Dolomite was named for the French mineralogist Deodat de Dolomieu. The mineral dolomite is commonly found in deposits of a sedimentary rock called dolostone. There are two types of materials often called dolomite, a true chemically uniform calcium magnesium carbonate with the chemical formula CaMg(CO3)2, and a dolomitic limestone, which is just an irregular mixture of calcium and magnesium carbonates.
