Applications of Natural Gypsum and Gypsum Containing Waste

Strommachina offers you a brief overview of applications of natural gypsum containing materials as well as gypsum containing waste.

Main consumers of natural gypsum materials are:

  • The gypsum industry. Manufacturing of gypsum plasters and binders both resistant and nonresistant to water as well as high-strength gypsum.
  • Cement industry. Manufacturing Portland cement often requires an addition of gypsum for quicker setting period (roughly 3% of total cement mass). Gypsum is often used for special cement production.
  • Chemical industry. Complex usage of Portland cement and sulfuric acid. Manufacturing of nitrogen fertilizers, ammonium sulfate, and other compounds.
  • Paper industry. Gypsum is necessary when manufacturing high quality white paper.
  • Agriculture. Fertilizing soils with gypsum requires from 0.5 to 1 ton of material per hectare.
  • Other industries. Anhydrates and selenite are both used in sculpture. Gypsum and anhydrates are necessary to finish walls and renovate sculpture. Selenite and satin span are used in optics.
  • Gypsum containing waste may be used for all aforementioned purposes after inspecting whether it is safe to use considering environmental safety. Waste is often used to produce asphalt.

Waste with phosphate gypsum can be used to produce sulfuric acid, Portland cement, and lime.

Some types of gypsum containing waste can be used as ingredients in Portland cement manufacturing. After adding 3% of phosphate gypsum containing material to the mixture, the roasting of the material significantly accelerates. Due to better productivity and performance improvements, the consumption of fuel also goes down. Setting period of cement is also improved greatly.
