:: Limestone ::

Limestone is a sedimentary rock composed largely of the mineral calcite. Like most other sedimentary rocks, limestones are composed of grains; however, most grains in limestone are skeletal fragments of marine organisms such as coral or foraminifera. Other carbonate grains comprising limestones are ooids, peloids, intraclasts, and extraclasts. Some limestones do not consist of grains at all and are formed completely by the chemical precipitation of calcite or aragonite.

Limestone is partially soluble, especially in acid, and therefore forms many erosional landforms. These include limestone pavements, pot holes, cenotes, caves and gorges. Such erosion landscapes are known as karsts. Limestone is less resistant than most igneous rocks, but more resistant than most other sedimentary rocks. Limestone is therefore usually associated with hills and downland and occurs in regions with other sedimentary rocks, typically clays.

Kota Stone

Kota Stone is a fine-grained variety of limestone, quarried at Kota district, Rajasthan, India. Many hundreds of mines are located in or near the town of Ramganj mandi and kota district. Kota Stone is famous for its low price and beautiful colors. The rich greenish-blue and brown colours of this stone are most popular. It is an excellent building stone. It is mainly used for Exteriors, Pathways, Corridors, Driveways, Balconies, Commercial buildings etc. It is also suitable for use in chemical industries as flooring, wall fixing & lining. People like Kota stones due to its charming appearance and long life. Kota stone is preferred for flooring and wall cladding, paving and facades of buildings. They are very tough, non water-absorbent, non-slip, non-porous and have excellent stain removability. Moreover, their resistance to wear and delimitation is higher than other stones.

Both Kota Blue & Brown are extremely versatile limestone’s and can be well honed, polished, sandblasted, brushed & tumbled. Hence they can be supplied in a variety of finishes.

Polishing: Polishing brings the shine and smoothness to the surface of stone after cutting into pieces of different sizes and thickness.

Other uses of Limestone:

• The manufacture of quicklime (calcium oxide) and slaked lime (calcium hydroxide);

• Cement and mortar;

• Pulverized limestone is used as a soil conditioner to neutralize acidic soil conditions;

• Crushed for use as aggregate—the solid base for many roads;

• Geological formations of limestone are among the best petroleum reservoirs;

• As a reagent in flue gas desulfurization (sulfur dioxide air pollution control);

• Glass making, in some circumstances;

• Added to paper, plastics, paint, tiles, and other materials as both white pigment and a cheap filler.

• Toothpaste

• Suppression of methane explosions in underground coal mines

• Added to bread and cereals as a source of calcium

• Calcium supplement for poultry (when ground up)[8]

• Remineralizing and increasing the alkalinity of purified water to prevent pipe corrosion and to return essential nutrients [9]

• Used in blast furnaces to extract iron from its ore

• Medicines

• Cosmetics

• Art (sculptures)
