In this work the influence of alumo-chrome catalyst on the properties and structure of anhydrite binder by means of mechanical tests, X-ray phase analysis and raster electron microscopy was investigated. Taking into account the high dispersity in the presence of alumina in the amorphous state, the catalyst intensifies the solidification of anhydrite composition increasing the mechanical strength by 80–100%. The catalyst also influences on the morphology and size of gypsum crystals. The addition of the catalyst in the range of 2–5% leads to the formation compact fine-grained structure, it allows increasing the mechanical properties of anhydrite binder.
