In recent years, studies have begun on the possibility of using anhydrite binders. However, the slow hardening makes it difficult to use this binder for residential and civil construction. The elimination of these difficulties is possible as a result of a deep and comprehensive study of the hardening process of anhydrite binder and the properties of the resulting stone, will make it possible to develop a technology for the manufacture of various building structures based on this binder.
