Properties:
Sulfate resistance portland cement is the special cement with high erosion resistance and strength. It has good compatibility with ordinary portland cements and other additives.
Application:
Sulfate resistance portland cement are mainly used in costal , port, sulfate underground construction. Such as fabrication of pipes which are likely to be buried in marshy region or sulphate bearing soils, marine conditions, concrete to be used in foundation and basement, and the construction of sewage treatment works.
Packing: 50kg 3-layers kraft paper waterproof bag. Small bags in jumbo bag of 2tons. Or according to customer’s requirement.
