2.2 Evaluation of chemical reactivity. To evaluate the chemical reactivity of the single calcined clays, the soluble silicon and aluminum ions in MOH were determined after 6 and 24 h according to Beuntner and Thienel. 36 1 g of the sample was eluted in 400 ml MOH on an interval agitator. The eluate was filtered and acidified to a pH of 1.0 after the corresponding time.
