Raw materials used for Cement Production

The purest grades of limestone are calcspar (calcite) and aragon­ite. Calcite crystallizes hexagonally, and aragonite is rhombic. The specific gravity of calcite is 2.7 and of aragonite 2.95. A macroscopic-granular variety of cal­cite is marble. It would not be profitable to use marble for cement manufacture.
