Physical PropertiesPhysically, Limestone are Quite impervious, Hard, Compact, fine to very fine grained calcareous rocks of sedimentary nature.
Hardness – 3 to 4 on Moh’s Scale Density – 2.5 to 2.65 Kg/m3 Compressive Strength – 1800 to 2100 Kg/cm2 Water Absorption – Less than 1% Porosity – Quite low Weather Impact – Resistant
Chemical PropertiesChemically, both limestone and marbles are siliceous calcium carbonate rocks.
Lime (CaO) – 38-42% Silica (SiO2) – 20-25% Alumina (Al2O3) – 2-4% Other Oxides like Na, Mg – 1.5 to 2.5% Loss On Ignition (LOI) – 30-32%
