About 2% of the plaster is used in the construction industry for wall plastering – various mortars and more. Normally, the color of the plaster is white, and the plaster surface can be painted with oil or plastic. The plaster does not emit sound and its thermal transfer coefficient is low and it does not burn and prevent the spread of fire. Because during the fire the water in the gypsum is removed and as a result some water vapor is collected under the plaster. And the presence of this water vapor causes the temperature to not exceed 2 degrees.
Construction mortar should not start earlier than 4-5 minutes and end later than 4-5 minutes and white plaster time should not start earlier than four minutes. And finish in less than 1 minute.
Application of gypsum in medical field
Chalk plastering
Gypsum is used to stain gypsum walls – whitening surfaces – molding as well as to close the broken organ.
If this plaster is mixed with a certain amount of water and lime. An endodontic is obtained that is rapidly retained and free of contractile cracks

Plaster molding
This type of gypsum powder is much smaller than a broken gypsum powder. The gypsum is slow to absorb and the heat is lower than that.
For this reason, they use it to mold decorative parts.
