Limestone (Kota Stone)

A fine grained sedimentary rock. It is primarily composed of calcium carbonate in the form of calcite or aragonite. Trace amounts of dolomite, iron oxide, quartz, clay or organic particles can also be present.Due to these impurities Limestone can vary in color. It is softer and more easily worked than marble. It has shown high resistance in freezing & thawing conditions, which indicate that it can be used in any atmospheric conditions. Lime stone is the most durable stone. It is known for its great strength as it does not blister upon exposing it to water. It is oil resistant and non slippery, therefore, well suited for flooring purpose. It can be also be used in any weather, as extreme degree of temperature, cold or hot, hardly affects the colour and texture of limestones. Usually used for wall-cladding, limestone flooring, limestone tiles etc of large complexes
