Gypsum, as one of the oldest building materials, is also a recognized environmentally friendly building material. Its application in construction is gradually expanding with the support of the power of science and technology, from complex high-tech content systems to easy-to-install components for public use, gypsum can be found.

Gypsum is helping people to build more and better environment-friendly buildings with its own advantages.Gypsum High Quality And Environmental Protection Building Materials - Gypsum

Long History

Gypsum is a rock-like mineral commonly found in the earth’s crust and is generally white, colorless or gray in color. The earliest recorded use of gypsum dates back to the city of Catal Huyuk in Asia Minor, 11,000 years ago. According to archaeological records, a large amount of plaster was used in the interior walls of Egyptian pyramids, which are still intact.

It is evident that plaster has been used in architectural decoration since ancient times, and with the advancement of technology, the scope of application of plaster in the field of architecture is constantly expanding.

Obvious Advantages

Gypsum is an inorganic mineral gel, which is green, strong and 100% recyclable, and is suitable for various building systems due to its good properties.

  1. Gypsum has good fire resistance performance, which effectively ensures the safety of buildings.

Gypsum is an inorganic material with non-combustibility. Its final hydration product, calcium sulfate dihydrate, contains two crystal water, and its decomposition temperature is about 1070 degrees Celsius to 1700 degrees Celsius. Therefore, when encountering a fire, only when all the two crystalline waters are decomposed, the temperature can continue to rise on the basis of about 1000 degrees Celsius; moreover, the large amount of water vapor produced during its decomposition can also play a role in blocking the spread of flame.Gypsum High Quality And Environmental Protection Building Materials - Gypsum

  1. Gypsum is conducive to the automatic adjustment of indoor humidity.

Its water-paste ratio is generally between 0.6~0.8. After hardening by hydration, a large amount of free water will be evaporated, leaving a large number of pores in the product and forming a porous material, whose bulk density is less than 1.0.

The advantage of porosity of gypsum building materials is also reflected in the fact that when the indoor humidity is high, these pores can inhale the water; on the contrary, when the indoor humidity is low, the water in the pores can be released, automatically adjusting the indoor humidity and making people feel comfortable.Gypsum High Quality And Environmental Protection Building Materials - Gypsum

  1. As a building material, gypsum is easy and flexible to produce, and the construction period is short, which makes gypsum can fully meet people’s requirements for various indoor functions.

Gypsum building materials are suitable for indoor roof, wall and floor. By choosing different varieties and different construction combinations, they can meet the functional requirements of indoor heat preservation, sound insulation, fire prevention, waterproofing and flexible separation, etc., and they are also good decorative materials for indoor.
