The article presents the results of a study on the properties and structure of gypsum ceramics based on fluoroanhydrite binder obtained by semi-dry pressing. To improve the properties of the fired compositions, a solution of sodium chloride was used instead of mixing water, which acted as a flux during firing. Based on the results of the differential thermal analysis and the main physical and technical characteristics of the compositions (compressive strength, shrinkage, softening coefficient), the optimal firing temperature was established, which was equal to 800оC. The optimal concentration of the NaCl salt in the solution was also determined. It has been found out that under conditions of high humidity the strength gain of the obtained gypsum-ceramic material continues even after reaching its project value due to the hydration of anhydrite.
