Limestone is sedimentry rocks that are formed at the bottom of lakes and seas,as slit and organic matter settle to the bottom.The great Sphinx of Egypt is a masterpiece of Sculpted Limestone.
Characteristically flaggy Lime Stone is very hard, has zero oil absorption and very low water absorption. It has comprehensive strength twice that of Marble.
Limestone being a natural stone, there can be variation in color &shade.
The capacity of water absorption is not more than 1.0%
Lies between 6 to 7 on Moh's Scale Density 2.32 to 2.42 Kg/m3
Sandstone is available in many colors – red, green, yellow, pink, gray and white.
The porosity of sandstone is almost negligible. Thus sandstone is almost impermeable.
Limestone is a sedimentary rock and is mainly made of calcite and aragonite, which are nothing but Calcium carbonate crystals. Limestone comprises approximately 10% of the total sedimentary rock population.
