Title: Reaction Models for Alkali-Activated Slags

Abstract:This paper addresses the reaction of alkali activated slags (AAS). First, from literature the most abundant hydration products formed from the hydration of slags are summarized. These products include C-S-H, a hydrotalcite-like phase, a hydrogarnet phase, AFm phases (C4AH13 and CzASHs) and ettringite. Then, two reaction models are established which correlate the mineral composition of the slag (the glass part) with hydration products. Using the proposed models, quantities of hydration products and composition of C-S-H formed can be determined. Finally, the models are applied to four slags selected from literature, and conclusions are drawn.
