Abstract

The mineral phases and pore solution composition of hydrated cement-solidified saltstone waste forms are quantified using thermogravimetric analysis, quantitative X-ray diffraction, and inductively-coupled plasma. The results suggest that, after 6 months to a year, the mineral phases present and the composition of the pore solution are stable, and are generally consistent with expectations based on the hydration of high volume portland cement replacement mixtures. Because the microstructural development is slow, compared to portland cement systems, additional work is needed to develop reliable models for the rate of hydration for these types of mixtures.
