A new publication titled “Dissolution Kinetics of Calcined Kaolinite and Montmorillonite in Alkaline Conditions: Evidence for Reactive Al(V) Sites” was published in Journal of the American Ceramic Society in July 2019.
Using solid-state Nuclear Magnetic Resonance spectroscopy and Inductively-coupled Plasma – Optical Emission Spectroscopy, we followed the dissolution kinetics of calcined kaolinite and montmorillonite. It was shown that dissolution kinetics are correlated with pozzolanic reactivity and dissolution rates are strongly influenced by the presence of reactive Al(V) sites.
