Abstract
The alkalinity of Portland cements is responsible for precipitation and low solubility of many radwaste species. The sources of alkalinity are evaluated and two chemical models, based on experimental and theoretical data presented, enabling the effect of blending agents (PFA, silica fume, etc. ) to be evaluated and the alkalinity of the system at longer ages predicted. The data take the form of a solubility model which is applicable to non-heat generating wastes.
