Sulphate Resisting Cement is recommended for all types of concrete structures and foundations near the sea and those areas where soil is rich in salts.

Zeal Pak Sulphate Resisting Cement has the following special characteristics:

  1. It has very low C3A (Tri Calcium Aluminate) and hence very resistant to sulphate attack.
  2. Low alkali content.
  3. Low heat of hydration.
  4. High compressive strength.
  5. Less initial setting time.

It gives remarkable resistance against sulphate salts attack and ensures prolonged life of the concrete structure.
