Applications of Limestone Powder: A Complete Guide
August 26, 2022 - By Carmel Group
Sedimentary rock like limestone is a common form of rock in the earth's crust. The main component of the limestone is mineral calcite, which is another version of the chemical combination calcium carbonate (CaCO3). Along with those substances, it also includes quartz, clay minerals, pyrite, feldspar, and siderite, to name a few. In terms of its physical characteristics, limestone typically ranges from rocks with an extremely fine texture to rocks with coarse texture. In addition, there are numerous names and varieties of limestone including oolitic, fossiliferous, lithographic, travertine, coquina, and chalk. Each rock has been divided into different categories depending on its composition, appearance, and various other characteristics. Here are some common uses of limestone you should know. Browse through them.
Limestone in Construction Industry
Limestone is quarried and is divided into blocks or slabs with predetermined sizes to meet the demands of the building and construction sectors. It can be used for varied uses, such as stair steps, window sills, floor tiles, and sculptures. Limestone was used in the construction of Egypt's famed pyramid at Giza. Also used in the manufacture of cement, limestones with a clay component are a viable construction combination. Additionally, limestone aggregate is used in the construction of roads and railroads.
Limestone for Environmental Treatment
The primary component of limestone powder is CaCO3, a type of natural salt. Salts can neutralise acids and get rid of other harmful compounds. So, limestone powder is frequently used to treat and safeguard the environment.
Limestone in Agriculture
Piggybacking to the previous fact, the majority of limestone is calcium carbonate compound. As a result, this chemical can be used in agriculture. Typically, limestone is crushed into smaller pieces to produce different grades. These are marketed as "agricultural lime" or "Aglime," which is utilised to balance soil acidity and release soil minerals like phosphates.
Limestone in Paper Industry
Clay and kaolin were used as fillers and coatings in the past to whiten paper during manufacture. However, these two types of land are so expensive and rare in nature. So, people are switching to other substances. The paper industry is more leaning toward limestone powder since it is one of the easily available fillers that result in whiter and even more affordable.
Limestone in Wastewater Treatment System
When limestone is pulverized, it creates tiny filter stones with cleaning and cleansing qualities.
These filter stones can be used to filter and treat wastewater in sewage systems. Lime, which is derived from limestone, can also be used to remediate tainted water sources and neutralize acids.
Lime Stone in Steel Industry
The steel industry, specifically the production process, makes extensive use of limestone. Limestone is utilized in this procedure to absorb and then remove impurities from the steel metals.
Limestone often reminds people of cement and buildings. However, this article has given you insight into the range of applications for limestone. Far from being a building material, it also serves as a foundation for many other significant goods.
