Carboniferous limestone takes form as either a fine-grained calcite mud in ancient shallow seas or as shelly limestone. Shelly limestone forms from layers of crushed coral. Both find use in industry as strong stones for use in roads, cement, and architecture. Caches of limestone from different locations can possess different hardness scores.
Rocks are rated on the on the Moh's Hardness Scale which rates the rocks on the scale from 1 to 10. Rocks with hardness 1-3 are soft rocks from 3-6 are medium hardness rocks and 6-10 are hard rocks. The hardness of Limestone is 3-4 whereas its compressive strength is 115.00 N/mm 2. Streak is the color of rock when it is crushed or powdered.
