How is calcium carbonate used in everyday life?

Building Materials and Construction

Calcium carbonate is critical to the construction industry as an ingredient of cement. It contributes to the making of mortar used in skim coating, rubber compounds and tiles.

Paper, Paints, and Coatings

Calcium carbonate is the most widely used mineral in the paper, plastics, paints and coatings industries both as a filler – and due to its special white colour – as a coating pigment. In the paper industry it is valued worldwide for its high brightness and light scattering characteristics, and is used as an inexpensive filler to make bright opaque paper. Filler is used at the wet-end of paper making machines, and calcium carbonate filler allows for the paper to be bright and smooth. As an extender, calcium carbonate can represent as much as 30% by weight in paints. Calcium carbonate also is used widely as a filler in adhesives, and sealants.

Agriculture Industry

Massive uses of nitrogen accommodating fertilizers, Soils become acidic. That’s why soil conditioner is used. To change the soil from acidic to neutral benefits crops using finely-ground dolomite and calcium carbonate can maximize acquirable of plant nutriments, decrease aluminum infectious and enhance the soil formation.

Rubber Industry

One of the important used fillers in the rubber industrial is calcium carbonate. In order to enhance the volume of its products and save pricey natural rubber or synthetic rubber, a significant amount of calcium carbonate powder is added to rubber. Rubber is loaded with calcium carbonate to increase its tensile strength, tear strength, and abrasion resistance compared to pure rubber vulcanizates.

Feed Industry for Poultry

Calcium carbonate powder with application for all animal and poultry feed products is a calcium content supplement and mineral supplement for livestock. Calcium carbonate is essential for egg formation and bone growth.

Water and Environment Treatment

The present invention relates to a process for the purification of water, wherein a surface-reacted natural calcium carbonate is brought into contact with the water to be purified, the surface-reacted natural calcium carbonate being the reaction product of a natural calcium carbonate with an acid and carbon dioxide, which is formed in situ by the acid treatment and/or supplied externally.

Manufacturing Industrial

Calcium Carbonate can be gentle abrasive action gently polishes tooth enamel without damaging it for tooth paste production.

Calcium carbonate powder is used as a filler agent for soap powder. It is easy in dish-washing bars especially helpful in dart removal.
