Dolomitization can completely alter a limestone into a dolomite or partially alter the rock. Dolomite is slightly harder than limestone. Dolomite has aMohs hardness of 3.5 to 4 and limestone (composed of the mineral calcite) has a hardness of 3. concrete. Most of the properties of concrete depend on cement.

To take a simple example: consider two manufactured coarse aggregates, both dense and unweathered, one composed principally of crystalline calcite and the other of crystalline dolomite, but both known as limestone. Classification of the carbonate rocks used as aggregate should be based on structure and on composition and texture.
