Combined Method of Water Treatment for Sealing Gypsum Systems and Materials Based on Them

The paper considers technologies for producing gypsum binders sealed with water that has passed through microwave (ultra - high-frequency) radiation, a permanent magnet field, and a combined processing method. Methods of mixing water treatment for gypsum binders are proposed, which provide high strength of gypsum systems, the introduction of substances of various concentrations improves the conductive properties of systems, reduces electrical resistance and increases electrical conductivity. The introduction of iron oxides of various degrees of oxidation contributes to the production of composite materials with a mixed type of conductivity. This paper uses the method of introducing low concentrations of iron chloride into the mixing water and treating the solutions with a microwave field and a magnetic field at different stages of the hardening process of a gypsum system based on iron oxides, which allows you to adjust the properties of the resulting gypsum matrix when using it. Methods of processing binders encapsulated in a gypsum matrix are analyzed, which in the future will make it possible to obtain structural composites with mixed electron-ion conductivity, which have high strength and controlled conductivity, in contrast to conventional gypsum systems used for the repair of construction objects.
