In fact, gypsum is present in a lot of places in our lives. It is the image of a white forehead like a plaster statue, gypsum in dentistry, gypsum for medical purposes, or a plaster ceiling. What is more surprising is that gypsum have been used  in the construction industry  since ancient times and are now a trend in construction.

Let's find out how we discovered and way of applying gypsum!

What is gypsum?

Gypsum is a crystalline mineral of hydrated calcium sulphate (chemical formulaCaSO4. 2H2O).

In its natural form, gypsum has a chemical formula of Calcium Sulfate Dihydrate, also known as gypsum with two water molecules (CaSO4.2H2O), with the proportion of water accounting for about 21% of the molecular weight. This material, when heated at a temperature of 150°C, will become Calcium Sulfate Hemihydrate, also known as semi-aqueous gypsum.

In nature, gypsum is found in gypsum mineral deposits. Besides, gypsum can also be generated in chemical plants, or at thermal power plants through the desulfurization reaction of sulfur dioxide.

The first applications of gypsum

First of all, gypsum was used as a cement material used to fix the overlapping stone slabs during the construction of the Pyramids. In addition, gypsum ore is also used as a raw material for finely honed (Jewel - Alabaster) stone used for coffins in the tombs of Royal family members such as King Khufu.

In the 13th century, calcined plaster was an indispensable decorative material in European palaces. As the era of European civilization developed, gypsum officially became a widely used architectural material. King Henry II of England praised the good quality plaster produced in Paris, France by the name "Plaster of Paris", and this gypsum was used to decorate Westminster Abbey and the castle Nottingham.

By the 16th century, once again the name "gypsum" made the Baroque style, Rococo full of charm and still remain in the history of architecture. Originating from the Renaissance culture was born in Florence Italy and gypsum spread throughout Western Europe. People used gypsum as a main component of interior decoration in the churches in the Baroque, Rococo’ style at that time.

In the 17th century, gypsum powder, gypsym board was officially born in North America, Canada. At the same time as the discovery of mainland America, a large number of people migrated from Europe towards the new land. The first buildings began to "sprout" on the land rich in wood and plaster materials. However, the design is slightly different from European stone architecture. The outside wall is built of Log house wood, while the interior uses a thick layer of fireproof plaster. Not long after the demand for housing increased, the use of drywall became money to develop into gypsum board material - a product with a sustainable connection in interior construction.

Market trend in gypsum

To be able to become a building material, gypsum board was produced by heating gypsum containing two water molecules into gypsum containing half a water molecule. Then mix this mixture with water, sandwiched between the two sides of the paper to shape. The final product is dried to remove some of the water and cut into a finished gypsum board.

Today, gypsum board is widely used in the field of construction: the product is an indispensable interior material for making ceilings and interior partitions for all works. With the internal structure of gypsum material, gypsum board has basic characteristics such as sound insulation, heat insulation, fire resistance and environmental friendliness. At the same time, gypsum board is also a material that is stable in size, light in weight and helps the team of contractors to easily install and install in different large and small construction projects.
