Portland Sulphate Resisting Clinker C3A ≤ 5%

Portland Sulfate Resisting Cement Clinker

  • Portland sulfate resisting  cement clinker is the main component of Portland sulfate resisting cement types as it accounts from 80% to 95% of Portland cement weight
  • Portland sulfate resisting  cement clinker is produced in cement kiln burning process of a mixture of Limestone Ca CO3 & Clay materials including aluminate, silicate & high ferrate content raw materials at 1450-degree Celsius
  • An addition of iron ore is included in the raw mix of clinker to enable reducing the Tri-Calcium aluminate to less than 5% of clinker weight composition & instead increasing Tetra-calcium alumoferrate C3AF that has the same function of regulating cement setting with the Gypsum content with comparatively lower expansive ettringite reaction wit Gypsum
  • The clinker component produced in the cement kiln has a particle diameter range from 5mm to 25mm
  • Cement Group plants includes a minimum content of 52% C3S

Advantages

01

High C3S content

02

Perfect mixing with cementitious materials due to high C3S content

03

Enable achieving required compressive strength results at different product mixing ratio
