4. Sorel Cement. Sorel cement is prepared by adding strong magnesium chloride to ground calcinated magnesia finely. Within 34 hours, it sets to a hard mass. The rate of hardening of the cement increases with the addition of % calcium chloride. The advantage of sorel cement is its accelerated rate of setting, which is useful during cold weather.
