Limestone Uses in Agriculture, Industries, Construction and Architecture

Uses of Limestone in agriculture, industries, construction and architecture are to be discussed here. Limestone is a type of a sedimentary rock that is found naturally in the earth’s environment. The rock comprises primarily of chemical compound calcium carbonate in the form of calcite which is yet again a type of a mineral. It also contains other materials like quartz, clay minerals, pyrite, feldspar, and siderite amongst others.

Limestone an Organic Substance

As for the physical properties, limestone usually varies between very fine-textured rocks and coarse-textured rocks. Further, there are many different types and names of limestone like chalk, coquina, travertine, tufa, fossiliferous limestone, lithographic limestone, oolitic limestone. They have been categorized based on how each rock is formed, how it looks, composition, and some other factors.

Different Uses of Limestone

When we talk about the uses of limestone, the first thing that strikes our mind is Construction. Well, architecture (or construction) is one space where they are dependent on limestone to a great extent. Interestingly, as this rock is so valuable and important, buyers are ready to pay even five times more than the value of the stone mostly for delivery. However, apart from architecture, there are several other uses of this rock as well. We will look at them in detail.

• Agriculture
• Industries
• Construction and Architecture
• Other Uses

Agriculture

We have already said that limestone deposits contain mostly calcium carbonate compound. As such, this compound can be quarried to be used by the farming sector. Usually, limestone is crushed into smaller particles and various grades are produced. Finally, these products are sold as agricultural lime or Aglime which is again used to neutralize soil acidity as well as free up soil minerals like phosphates.

Industries

There are several industries that make use of limestone. As such, powdered limestone is used in the textile, paint, paper, rubber, glass and plastic industries amongst others. They are mostly used as fillers. Apart from this, it is used in the steel industry for the production process where limestone is used to remove impurities. The minerals found in limestones are also used in pharmaceuticals, cosmetic products, baking soda, toothpaste, etc.

Construction and Architecture

Here limestone is quarried to service the needs of the building and construction industries. So the stone is cut into either slabs or blocks with specific dimensions. Some of its applications include sculptors, floor tiles, window sills, stair treads, and others. The famous pyramid of Giza in Egypt is made out of limestone. Additionally, limestones containing clay content are utilized in the production of cement. Limestone aggregate is also used in road and railroad construction.

Other Uses of Limestone

Crushed limestone is used as a filter stone in on-site sewage disposal systems. Limestone in powdered form is also used as a substance to absorb pollutants or control coal mine dust at many coal-mining facilities. Lime which is the byproduct of limestone is used to neutralize acids and treat wastewater, industrial sludge, animal waste, and water supplies.
