Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). It is commonly composed of tiny fossils, shell fragments, and other fossilized debris.

Limestone is highly uniform and consistent, with specific gravity varying between 2.69 and 2.71; water absorption less than 0.5%; and Magnesium Sulphate Soundness of less than 1.0%. The rock has a hardness value of between 5 and 6 on Moh’s scale.
