Sulfate resisting cement is used to reduce the risk of sulfate attack on concrete and thus is used in the construction of foundations where the soil has high sulfate content. This cement has reduced the contents of C3A and C4AF.
Sulfate resisting cement is used in construction exposed to severe sulfate action by water and soil in places like canals linings, culverts, retaining walls, siphons, etc.
Characteristics of Sulphate Resisting Cement:
This cement provides maximum resistance to chloride ions – minimising the risk of corrosion of reinforced steel.
It also provides high level of concrete performance and structural integrity in highly aggressive sulphate and acidic environments.
It also has increased workability and pumpability.
This cement has significantly improved later-age concrete strengths.
