Abstract

This article presents results of a research on changes in energy parameters of fluorogypsum composition of normal consistency with introduction of various additives (μΔn) such as sodium sulfate and sodium sulfite. Activity of binder in interaction with water was defined as the sum of thermal effect of hydration and thermal effect of dispersion of fluorogypsum crystal lattice. In order to compare processes of heat release in the studied gypsum-containing systems, the article presents results of analysis for the following ones: fluorogypsum binder – water, fluorogypsum binder – sodium sulfate – water and fluorogypsum binder – sodium sulfite – water. Research has shown that processes of hydration during by development of alternating exothermic and endothermic effects in systems containing fluorogypsum binders.
