Limestone is a non-clastic sedimentary rock consisting of more than 50% calcite (a calcium carbonate mineral, CaCO3). Limestone is mostly a biological rock that forms in clear, warm, and shallow marine waters. Limestone exists in various types and colors.Limestone has low porosity; it is weather resistant and has a density of between 2.5 and 2.7 kg/cm3. It has a hardness of between 3 and 4 on Moh’s Scale and a water absorption of less than 1 percent.Limestone, on the other hand, is very widespread.
