Calcium Carbonate-PPT

Calcium carbonate is a chemical compound with the formula CaCO3. It is one of the most abundant minerals on Earth and is found in various natural forms such as limestone, chalk, and marble. Calcium carbonate is also produced synthetically for a wide range of industrial applications.

Industrial Applications:

• Construction Industry: Calcium carbonate is a key ingredient in the production of cement, concrete, and mortar. It acts as a filler, providing strength, durability, and bulk to these construction materials.
• Paper Industry: In the paper industry, calcium carbonate is used as a filler and coating pigment in the production of paper and paperboard. It improves the paper’s brightness, opacity, and printing properties while reducing production costs.
• Plastics and Polymers: Calcium carbonate is widely used as a filler in plastics and polymers to improve mechanical properties, reduce production costs, and enhance processing characteristics.
• Paints and Coatings: In paints, calcium carbonate serves as an extender and pigment, improving coverage, opacity, and rheological properties. It is commonly used in interior and exterior paints, coatings, and primers.
• Pharmaceuticals and Dietary Supplements: Calcium carbonate is a source of dietary calcium and is used as an antacid to relieve heartburn, indigestion, and upset stomach. It is also an ingredient in calcium supplements.
• Environmental Remediation: Calcium carbonate is used in environmental remediation processes, such as neutralization of acidic wastewater and soil stabilization.
