Uses of Limestone

Limestone is used to make buildings and is used as a base for roads.

It is mostly made of calcium carbonate which is an importnat raw material used in the production of glass, cement and concrete.

It is heated when making cement and glass. The heat decomposes the Calcium Carbonate (CaCO3) in it to form Calcium Oxide (CaO) and Carbon Dioxide (CO2).                                  This process is called Thermal Decomposition.

Advantages of Quarrying

  • Limestone is an important raw material so it makes quarrying worthwhile.

  • .Quarries provide jobs in the countryside
  • Some limestone is exported to other countries, which helps the UK economy.
  • Jobs in quarries also help local economies, because the workers spend their money in local shops and buisnesses.
