Calcium carbonate enhance coatings performance as known as functional filler. Filler quality can improve decorative paints opacity, brightness, reflectance, workability and more. As well as on industrial coating, filler selection can make huge difference impact on gloss, viscosity and durability.

The basic material in many adhesives and sealants are Calcium Carbonate, which are impoving rheologi, bond strength, and reducing water demand.

Glass are formed from certain types of rocks melt in high temperature and then cool and solidify rapidly. The function of calcium carbonate in glass production for stabilizer, modifies the viscosity and increases the durability. Other usage of calcium carbonate is reduce cost of ceramic production, because calcium carbonate is an economical source of calcium oxide which is needed as a melting agent that can improve mechanical and chemical strength and reduces shrinkage.

Calcium carbonate is well known for cemen based products, such as asphalt, roofing, tiles, and bricks. Calcium carbonate function in construction as stabilizer, accelerate the hydration of the cement matrix, increasing strength and durability.

With good selection of calcium carbonate grade, can reduce cost of rubber production and improve mixing effect, and mold release.

In order to increase the quality of natural or treated (e.g. desalinated) water to a non-corrosive level or to a level acceptable for human consumption, needs to adjust the pH value through neutralization, (re)mineralize the water through adding (dissolving) the required amount of calcium, magnesium and carbonate minerals or reduce the water hardness (decarbonization). An unsufficient level of calcium carbonate in treated water makes it corrosive and will cause equipment and structures to deteriorate, often while not fulfilling drinking water quality requirements such as those recommended by the WHO (World Health Organization). A supersaturated solution will likely precipitate calcium carbonate, causing scale, reduced efficiency and eventually leading to system failure.

Calcium and magnesium fertilizers were known used for fertilizers. Fertilizers help to improves soils, plant nutrition and plant protection.

Calcium is an essential mixing element for every animal species. In addition to the basic fodder, the requirements of individual species call for the addition of Calcium carbonate to the feed ratio. The beneficial effect of using calcium carbonate as animal feed is proper development of bones and teeth, regulation of heartbeat and blood clotting, muscle contraction and nerve impulses, enzyme activation and hormone secretion, eggshell formation and quality, and milk production.

The aim of good pond management is to increase fish production through an improved supply of natural food such as phytoplankton and zooplankton. The supply is usually increased by fertilizing the pond water. Addition of calcium carbonate at pond is called liming, liming can be done when the pH of the pond below 6.5, very muddy, controlling disease and pests, high concentration of organic matter, and total alkalinity below 25 mg/l CaCO3.
