The work was carried out to study gypsum composites modified with porous ceramic fillers. The demand for the development of such a material is due to the growing interest in gypsum and products based on it, which ensure high manufacturability during manufacture and use, as well as increased comfort and safety during the entire period of operation. It is proposed to provide high strength and performance characteristics of a gypsum composite material by modifying its structure with porous fillers, primarily by reducing the weight of products without reducing strength, due to the high strength of the introduced foam-filled modifier. Such a composite material will significantly expand the range of manufactured gypsum products based on it. Microdispersed foamed ceramics were used as a filler. The introduction of an aluminosilicate modifier promotes the formation of a lightweight gypsum stone with a developed homogeneous porous structure of ceramic foam inclusions. It is shown that the modifier is involved in phase transformations, contributing to the strengthening of the contact at the modifier – gypsum phase interface. The performed microstructural analysis made it possible to confirm the participation of aluminosilicates in the process of structure formation of gypsum stone, which can be used in practice to create complex modified compositions based on gypsum binders.
