Description
Ternary binders are frequently used in fast-setting applications, such as rapid tile adhesives, where high early-age performance is required. In this context, the incorporation of ground granulated blast furnace slag (GGBS) offers an effective pathway to reduce the carbon footprint of construction materials, while maintaining reactivity and durability.
This research focuses on evaluating the hydration potential of a GGBS-rich ternary binder composed of calcium aluminate cement (CAC), calcium sulfate (C$), and GGBS. Hydration kinetics are investigated using isothermal microcalorimetry, and the mechanisms of phase formation are studied through microstructural characterization techniques, including X-ray diffraction (XRD) and magic-angle spinning nuclear magnetic resonance (MAS-NMR) of 27Al and 29Si.
The results highlight the effective reactivity of GGBS under the specific conditions and its significant contribution to the hydration process and the final properties of the binder system.
