The reactivities of calcined magnesites for industrial use and of magnesium oxides prepared from basic magnesium carbonate were assessed by using potentiometry to monitor pH changes in aqueous suspensions following step wise acid additions. The results were compared with those obtained by calorimetric measurements performed during formation of magnesium oxychloride cement. The quality of cements made using these materials was checked by compressive strength determinations and found to correlate well with the experimental reactivities.
