The article considers the behavior of a gypsum-based building material under thermal exposure. The dependence of the main physical and chemical characteristics on the heating temperature of gypsum fiber is shown. IR spectroscopy was used as an instrumental research method. Regularities between the temperature effect and the composition of materials based on gypsum are revealed. Differences in the IR spectra of materials based on gypsum are experimentally shown depending on the magnitude of the temperature effect.
