Abstract
A fairly large number of works by both Russian and foreign researchers have been devoted to the development of building materials based on anhydrite binders. An astringent based on insoluble anhydrite refers to slow-hardening. This fact often deters manufacturers of building materials from using this binder. To date, there are many activators for the hardening of insoluble anhydrite. The efficiency of accelerators depends on a number of factors. But there is no unambiguous explanation for the action of additives used to obtain anhydrite materials with optimal properties, and this problem needs a comprehensive study. The use of anhydrite in the production of building products and materials is a promising direction in construction, since anhydrite binder is an interchangeable local material and can be used instead of cement or gypsum binders.
