The subject of development is the process of directional structuring of artificial stone based on hybrid alkaline cements, as well as the formation of its micro- and macrostructure, with the aim of increasing corrosion resistance and durability. The purpose of the work is the development of acid-resistant materials based on hybrid alkaline cements in the R2O – RO – Al2O3 – SiO2 – H2O system with increased impermeability and reduced open porosity for use in products and structures of general construction and special purpose. Research methods: physico-chemical, physico-mechanical, chemical research methods in accordance with current regulatory documents. A thorough analysis of literary sources was carried out according to the direction of research. Selection of the composition and optimization of recipe solutions for obtaining acid-resistant materials on the basis of hybrid alkaline cements by using a two-factor experimental plan were carried out. The influence of the recipe composition on the indicators of hardening periods, physico-mechanical properties and indicators of acid resistance of materials was studied. Patterns of changes in the properties of hybrid alkaline cements depending on the component composition of the system were obtained. Product Description popup.authors Yezerska Liudmyla P.
