  • Calcium carbonate - Wikipedia

    OverviewUsesChemistryPreparationStructureOccurrenceGeologyCalcination equilibrium

    The main use of calcium carbonate is in the construction industry, either as a building material, or limestone aggregate for road building, as an ingredient of cement, or as the starting material for the preparation of builders' lime by burning in a kiln. However, because of weathering mainly caused by acid rain, calcium carbonate (in limestone form) is no longer used for building purposes on its own, but only as a raw primary substance for building materials.
