Interestingly, the Canadian city of Kingston in Ontario province has so many buildings made from limestone rock that the city itself has been nicknamed the Limestone City.
Other than the application of limestone rocks in construction directly, this rock is also applied in production of Portland cement which is a vital component in the field of construction. When we talk about applications of limestone in construction, its application in construction of roads and railroads – wherein it is applied in crushed form to form to lay the foundation, is also taken into consideration.
Not many people out there would need an introduction to limestone countertops which add to the grace of your kitchen. The application of minerals such as calcite and dolomite – which are found in abundance in limestone rocks, is also quite popular. These minerals are applied in the process of manufacturing products of daily application such as paper, baking soda, detergent, glass, textiles etc. Not many people must be aware of this, but the applications of limestone in toothpaste – wherein it acts as a filler, white pigment and abrasive, makes it an important constituent of your day-to-day life.

It is also applied in purification of molten glass as well as molten iron. The application of limestone in steel making along with iron ore and coke is also quite popular. In its pulverized form, limestone is applied as a soil conditioner to neutralize soil high in acidic content.
Going through this limestone rock information, which laid special emphasis on the applications of limestone, you must have realized why this sedimentary rock is considered to be so important for various industries. That being said, limestone applications are not restricted to the ones mentioned above. The erosional landforms carved out of limestone rock – known as karst in geology, plays an important role in natural landscaping. Similarly, the geological formations of limestone are considered to be the best petroleum reservoirs on the planet.
