Limestone is a sedimentary carbonate rock that is mostly composed of marine organism skeletal fragments. Calcite and aragonite crystals, which are various crystal types of calcium carbonate (CaCO3), are its primary ingredients. A closely related rock is dolomite, which contains a high percentage of CaMg(CO3)2, the mineral dolomite. Approximately 10% of sedimentary rocks are limestones.
Limestone has many uses: as a construction material, as an essential constituent of concrete (Portland Cement), as an aggregate for the road foundation, as a white pigment or filler in products such as toothpaste or paints, as a chemical feedstock for the manufacture of lime based products and as a soil conditioner.
