Sulfate-Resisting Cement

 

(also supersulfated cement), a variety of portland cement. Sulfate-resisting cement is more resistant than ordinary portland cement to the action of mineralized water containing sulfates; it also has lower heat of hydration, slower hardening, and higher frost resistance.

Sulfate-resisting cement is produced by the fine pulverization of clinker of standard mineral content. It is used in the production of concrete and reinforced-concrete components of hydroengineering installations that are exposed to a corrosive sulfate medium, such as seawater, especially under variable moisture conditions and in cases of alternating freezing and thawing.
