Chemical Properties

Chemically, 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%

 

Limestone, like marble and other calcareous stones, are referred to as acid sensitive. Calcareous stones are readily dissolved in acid, therefore acidic products should not be used on limestone and marbles.
