What is Gypsum Lump?

What is Gypsum Lumps? How does gypsum form? What are the features? Where to use?
Gypsum is a mineral whose chemical composition is calcium sulfate. Its type, which contains two molecules of crystalline water, is called gypsum (CaSO4 + 2H2O). Gypsum is found in 6 forms in nature. These; Anhydrite, Bassanite, Gypsum, Albatr, Silk Gypsum and Selenite. Natural anhydride is anhydrous calcium sulfate. It is seen that it is generally bedded with gypsum in nature. Except for sulfuric acid production in some countries, it has not been found much use until recently. However, it has gained importance in the chemical industry and construction materials construction for 30 years.
Gypsum, the raw material of gypsum, is formed by sea salt or as a result of the hydration of the moment hydride by surface or groundwater. Gypsum or gypsum is used as raw material in cement production, as a filler in fertilizer, paper and woven materials. It is used for making materials such as marble plaster and cement by roasting plaster.


Another type of plaster, bassanite, forms a separate mineral phase between anhydrite and plaster. Gypsum is abundant. In ancient times, after warming on gypsum plaster, Assyrians, Turks, Chinese, Greeks and Romans, especially Egyptians used it. However, in 1755, the consumption of plaster began to develop with the method of clarifying the plaster chemistry in France and delaying the plaster socket in 1870. Turkey is also known to use plaster of the Seljuk monuments. Considering the existence of 200 years old houses with gypsum plaster in Erzurum, it is understood that the plaster has been used since ancient times.
Gypsum obtained from cooking gypsum, powdered and firing at 158 degrees, is a fine white powder that quickly freezes when the chemical compound Calcium sulfate hemihydrate is heated and left to dry. Plaster, which is used especially in plaster ceiling and room partitions as a building material, is widely used to keep the fusion constant in bone fractures.



Usage Area

It is added to raw gypsum, white paint (Mineral white = terra alba) and paper and cotton textile materials as filling material.
Raw gypsum delays setting in cement industry.
It facilitates smelting in nickel smelting.
It is used for fermentation in the beer industry.
Gypsum is used in medicine, surgery and dentistry.
It is used in plaster vitrified materials, porcelain and tile production at the mold stage.
It is used in the chemical industry to obtain ammonium sulfate, sulfur, sulfur oxidized and sulfate acid.
It is the main input of finished plaster construction and prefabricated building materials.
The place of use of plaster in construction is very diverse. In recent years, hot and cold insulating material has been used as a sound insulator and a regulator that also adjusts moisture.
