Optimizing Composition of Gypsum Mixture for

Gypsum as a building material is formed by heating a raw material called plaster stone - CaSO 4 2H 2 O and can acquire various properties depending on how it is produced. Its resulting properties can be affected to some extent by the source from which the raw material for its production is obtained, whether it is plaster stone or whether it the source is a secondary product from industrial production.

Optimizing Composition of Gypsum Mixture for

Gypsum, or sulphate, binders are inorganic powder binders, which are among the so-called aerial mortars. These, after mixing with water, form a material that is well-workable for a certain time, which solidifies, hardens and is stable only in the air. Gypsum as a building material is formed by heating a raw material called plaster stone - CaSO42H2O and can acquire various properties ...
