What is Calcium Carbonate composed of?

Calcium Carbonate is composed of three elements which are of importance for all organic and inorganic material on our planet: Carbon, Oxygen and Calcium.

How is Calcium Carbonate used in the Paper Industry?

Calcium Carbonate is incorporated within paper products in two different ways: both as filler that enters the pulp before the web is formed, and as the main constituent of the coating formula, applied to the dry paper surface for further upgrading. In the manufacture of high quality printing paper, both of these processes are employed. It can be used in combination with kaolin and talc or as the sole mineral constituent of the paper.
Today over 10 million tonnes of calcium carbonate products are used annually in paper manufacturing.

How can Calcium Carbonate be used in Plastics Industry?

Calcium Carbonate can be used in fillers and reinforcing agents in plastics production. A wide selection of calcium carbonates in both uncoated and surface coated forms is now available and in terms of volume, they are the most important fillers in the plastics industry. In thermo plastics and thermosets more than 3.5 million tonnes are used annually and growing. Even adhesives and sealants consume about 900,000 tonnes of Calcium Carbonate as filler. It can be used a large range of products e.g. PVC.

How is Calcium Carbonate used in the Agricultural Industry?

Calcium Carbonate is an essential mineral for the healthy growth and development of livestock and domestic animals. It plays an important role in the metabolic process, retention and conversion of nutrients and regulates cell activity. It also supports healthy bone and skeleton development in young livestock. Calcium is one of the main minerals needed by animals to grow, develop and produce.
Its main function in the animal is for bone and teeth formation, smooth muscle contraction, e.g. the rumen, and for blood clotting. A deficiency or imbalance in calcium can cause poor growth rates, poor bone development, reduced milk output, displaced abomasums and more obviously milk fever. A lesser known fact is that it can also cause urinary calculi in male animals, (intact or castrated!). It is also vital for poultry to support healthy digestion and the strengthening and hardening shells.
Agricultural lime is a mineral fertilizer used to neutralize and nourish agricultural land. It corrects soil acidity and pH levels by neutralising the acids in soils so that the micro-organisms can thrive, break down plant and animal residues and free the elements required for healthy growth of the land. This is vital to maximise crop yield, animal grazing and good quality silage/hay.
We are currently one of the top producers of agricultural lime or Grolime in the West of Ireland and provide efficient and on time delivery and spreading. Our lime is tested twice annually by the Dept of Agricultural which in turn provides us with a licence to sell. We are also members of the Ground Limestone Producers Association.

Calcium Carbonate can help the environment. How is this possible?

CongCal Calcium Carbonate can also be used as a neutralisation agent to de-acidify lakes and rivers. Natural eco systems, habitats and drinking water can be seriously damaged by altered pH levels caused by acid rain or acidic water runoff from mines. To counteract or neutralize the damage you can engage in lake liming or spread CongCal Calcium Carbonate it increased the pH value and help to restore the natural balance of the eco system.It also can be used to neutralize acidic soil and reduce pH values, this in turn is known to produce a higher yield in crops for the agricultural industry.

How is Calcium Carbonate used in Construction Industry?

Calcium Carbonate is vital to the construction industry worldwide; both as a building material (limestone aggregate) and as an ingredient in various products. It is a natural mineral with a variety of unique characteristics which in turn lead to its variety of applications in the construction industry such as buildings, roads, civil engineering projects etc.
Self Compacting Concrete
Calcium Carbonate when added to concrete promotes self-compacting properties. The product has better workability, increased strength and improved appearance with a smoother surface.
Flow Screed is designed for application for finishing flooring in residential and commercial projects, and intended for use in unbounded, bonded and floating construction. It has an excellent crushing resistant and has fibre reinforcements.
Asphalt
Calcium Carbonate is used as a multi-purpose filler/anti-strip agent when added to hot rolled asphalt with various sands and gravels. It acts as a sand modifier to improve the resistance of the mixture and provide a consistent material that is easier to work with. It can also be used in paving, renders, ceramics, specialist grouts and cement.

Is Calcium Carbonate contained in every day products?

Calcium Carbonate is used in a range of products including: Glass, Asphalt, Concrete, Toothpaste, Pharmaceuticals, Steel Manufacturing and Plastics.
