The mechanism and kinetics of hydration of alkali-activated slag (AAS) have been studied. Heat of hydration, non-evaporable water content and hydration degree of AAS were examined. Similar to ordinary Portland cement (OPC), the hydration process of AAS could be classified into five stages: initial,
This paper examines the early hydration of alkali-slag cements activated by different sodium compounds, such as NaOH, Na&O,, Na$iO,.SH,O, Na,PO.,, N%HPO, and NaF, at 25 and 50°C. A conduction calorimeter was used to monitor hydration kinetics. It was found that the initial pH of activator solution h
