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 construction gypsum G-5AII and sodium sulfate. The effects were assessed by temperature changes in the binder – water system. In order to compare processes of heat release in the studied gypsum-containing systems, the article presents results of analysis for the following ones: construction gypsum – water, fluorogypsum binder – water, fluorogypsum binder – construction gypsum – water and fluorogypsum binder – sodium sulfate – water. All processes of hydration and structure formation occurring in the system of fluorogypsum – water are accompanied by a change in temperature, which can be measured using differential microcalorimetry.
