Limestone in India is available in various forms that contain different amounts of silica present in it. This silica can be either flint or chert. These are the sedimentary rocks that consist of CaCO3.These are impervious and hard with low water absorption capacity.Varation,texture,and color intensity,all depend on the types and proportion of impurities in limestone.Several world-Famous structures,both archaic and modern,are known to incorporate natural limestone in their construction.Historical buildings and monuments like Megalithic Temples of Malta,Great Sphinx of Giza,Beer Quarry Caves,Lincoln Memorial,and Empire State Building have been made of limestone that are hard,durable,weather-resistant,and beautiful. However, people prefer this stone to be part of their home architecture and for other landmarks. Usually, people use it in the form of tiles, slabs, wall cladding, and paving of the floor surface. Also, they use it in many other commercial areas, airports, hospitals, and shopping malls. The main properties that make it unique from other stones are resistance in freezing and thawing.
