Study on correlation between hydration characteristics and macroscopic properties of ferroaluminate cement system based on isothermal conduction calorimetry
Abstract:The hydration heat release and hydration characteristics of a ferroaluminate cement system were investigated using isothermal conduction calorimetry, with a focus on the correlation between its hydration behavior and macroscopic properties. The results indicate that in a ferroaluminate cement system blended solely with limestone, increasing the limestone content prolonged the initial and final setting times, while the compressive strength at various curing ages and the 7-day cumulative heat release exhibited a declining trend. In a system incorporating both limestone and slag, increasing the slag content caused the setting time to first extend, then shorten, and subsequently extend again. Meanwhile, the compressive strength and 7-day cumulative heat release initially decreased, followed by an increase, and ultimately decreased. A linear positive correlation was observed between the compressive strength of the ferroaluminate cement system and its cumulative hydration heat release at corresponding curing ages. Conversely, a linear negative correlation existed between the setting time and the 7-day cumulative hydration heat release.
