AbstractAbout AuthorsReferences
Without reducing the importance of numerous studies on the development of water-resistant gypsum-pozzolan binders, it should be noted that their production is mainly achieved with an increased content of Portland cement and active mineral additives in the mixture, in some cases – the use of gypsum with high strength. In this regard, of interest are the studies aimed at the development of water-resistant gypsum-pozzolan binder based on low-grade gypsum with a reduced content of Portland cement and active mineral additives, the hydration of which will provide conditions for the formation of stable structures. Some issues related to the study of the features of structure formation of such systems continue to be poorly studied. The objectives are achieved through the use of active mineral additives with high hydraulic activity, as well as multifunctional complex additives. The research carried out made it possible to establish influence of a complex of mineral and chemical additives on processes of hydration and structure formation of gypsum-cement-pozzolan stone, its limits of durability and water resistance, and also water demand of a mix.
