Limestones are composed largely of mineral calcite
and is an important stone for masonry and architecture. These natural
limestone from India are generally used as limestone tiles, limestone
slabs in flooring, wall cladding, vanity tops and to pave the floors of
large commercial complexes, hospitals, airports, shopping malls, railway
stations, parks etc. We can offer natural limestone in different

CHEMICAL
PROPERTIES OF LIMESTONE |
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. |
