1. COMPOSITION OF Limestone

Chemical formula: CaCO3 (Calcium Carbonate)

Limestone is a type of sedimentary rock, in terms of chemical composition, it is mainly calcite mineral. Limestone is rarely pure, but often mixed with impurities such as silicon shale, silica and igneous rock as well as clay, mud and sand, bitumen... So it has a color from white to ash, blue. light, yellow and also dark pink, black.

3. LICENSE APPLICATIONS

 

Silica limestone has higher strength, but is brittle and hard. Dolomite limestone has better mechanical properties. Limestone containing a lot of clay (greater than 3%) has poor water resistance. Although limestone is not as solid as granite, it is more common, easier to mine and process, and is therefore more widely used;
Limestone is the main raw material used to produce lime and cement for the construction industry;
Limestone is often used as an aggregate for concrete, for road pavement, for railways, and for irrigation works in general, as well as for making cladding, paving slabs and other architectural elements. ;
As a raw material commonly used in the steel industry;
Ceramic tile adhesives usually contain about 70-80% limestone;
At the same time, limestone is also an important source of raw materials for the production of light powder and basic chemical raw materials of soda:
           Light powder is used in many industries such as paper industry, rubber, plastic, foam, toothpaste, cosmetics, paint, pharmaceutical industry, etc.

          + Soda is also one of the essential basic chemicals of the national economy. Soda is used in many industries such as: as a raw material for the production of detergents, in the production of liquid glass, in the production of non-ferrous metals, in the cleaning of petroleum products, in the textile industry, in the production of cotton and silk. artificial etc...
