  • The Slag cement is more resistant to the attack of weathering agencies.
  • Low Cost to compare OPC.
  • It gives a smooth finish because the cement particles are more finesse.  


  • The PSC Cement is to be used mainly in mass concrete because of its heat hydration is lower than that of Ordinary Portland cement.
