Calcium Carbonate Applications

Calcium carbonate has a wide range of applications across various industries due to its abundance, low cost, and useful chemical and physical properties. In the construction industry, it is a key ingredient in the production of cement, lime, and building materials such as concrete and plaster. In agriculture, it is used to neutralize acidic soils (as agricultural lime) and as a calcium supplement for livestock. The plastics, rubber, and paper industries use finely ground calcium carbonate as a filler material to improve product strength, brightness, and surface finish. In the food and pharmaceutical sectors, it serves as a dietary calcium supplement and a mild antacid for treating heartburn and indigestion. Additionally, it is used in environmental applications, such as flue gas desulfurization, where it helps remove sulfur dioxide from emissions in power plants. Its versatility makes calcium carbonate one of the most widely used inorganic compounds in both commercial and industrial settings.
