USAGE: Calcium chloride has a salty taste and is the main ingredient in many types of food items including snacks. It is also found in beverages and sport drinks.
Calcium chloride is popularly used as a preservative in packed foods.
Calcium chloride is also often used as a dehydrating agent in the petrochemical industry, due to its ability to deprive a chemical compound of its water content.
Calcium chloride is often added to concrete mixes as it has been proved that concrete containing it hardens rapidly, thus reducing the time of setting. This chemical compound also provides greater concrete strength. Unlike other chemical compounds, it does not damage the concrete. Calcium chloride is exothermic (heat producing). When added in liquids to remove dissolved water, a huge amount of heat is released and the temperature can rise up to 60 degree Celsius. This property is often used to start the heating process required for industrial purposes.
The unique properties of calcium chloride such as the ability to attract moisture from air, quick dissolving and exothermic qualities have indeed made it a popular industrial chemical.
