The article discusses the history of creation, physical and chemical properties, and applications of alumina cement (AC) as a special type of binder. It analyzes the key differences between AC and Portland cement in terms of their mineralogical composition, hardening kinetics, and performance characteristics. Special attention is given to the issue of calcium hydroaluminate conversion, which plays a crucial role in the long-term reliability of AC-based materials. The article presents the current prospects for the development of alumina cement production in Russia, including the Ural Federal University's research on import substitution of this product. The article concludes that it is advisable to use alumina cement in special areas of construction, such as repair work, refractory and chemically resistant structures, and dry construction mixtures.
