Shrinkage mechanisms of alkali-activated slag [PDF]
Cement and Concrete Research, 2016 Abstract In this work, the physical and chemical changes of alkali-activated slag (AAS) after a prolonged drying treatment under various relative humidity (RH) conditions were studied. The results show that the shrinkage kinetics of AAS is strongly dependent on the RH, but irrespective of the moisture loss.

Properties of Alkali-Activated Slag Cement Activated by Weakly Alkaline Activator. [PDF]
Materials (Basel), 2023 Sodium sulfate (Na2SO4) and sodium carbonate (Na2CO3) are weakly alkaline activators. Alkali-activated slag (AAS) cement prepared with them shows the special advantages of long setting time and low shrinkage, but it shows slow development of mechanical properties.

Activator Anion Influences the Nanostructure of Alkali-Activated Slag Cements [PDF]
The Journal of Physical Chemistry C, 2021 Alkali-activated materials are promising low-carbon alternatives to Portland cement; however, there remains an absence of a fundamental understanding of the effect of different activator types on their reaction products at the atomic scale. Solid-state 27Al and 29Si magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy and 1H–29Si ...
