    Abstract. The article proposes a new principle for creating binding substances, namely imparting several mutually complementary properties to the binder simultaneously. As an example, it suggests providing fungicidal properties for radiation-protective materials used in medical facilities, pharmaceutical industries, and the electronics industry, where ionizing radiation is used and biosecurity requirements are imposed. This can be achieved by combining radiation-protective and fungicidal additives, which can influence the structure and properties of the materials. The article presents theoretical data on the possible effect of barium, zinc, and copper cations on the hydration of рortland cement, and the results of calculations of the minimum content of fungicidal modifiers. It is shown that when all of these additives are used, silica acid affects the onset or duration of setting. Copper cations significantly slow down the setting of the binder, which is due to the characteristics of the resulting copper hydroxide, and the strength of the resulting stone is reduced. Barium cations do not block the hydration of рortland cement minerals, their use makes it possible to increase the strength of the resulting binder. Zinc cations do not block the hydration process, unlike copper cations, but zinc hydroxides do not significantly increase the strength of the composite cement stone.
    Keywords: special binding agents, radiation-protective materials, fungicidal additives, hydroxysilicates of barium, zinc and copper, structure formation, setting time, compressive strength
