SikaGrind®-421

SikaGrind-421 is a chloride free, liquid additive to allow easier grinding of cement and enhance the quality of all types of cement. SikaGrind-421 has been specifically developed to obtain cements with increased early and final strengths.

SikaGrind-421 gives the following advantages to the finished cement:

  • Reduced handling costs especially on pneumatic conveying systems
  • Reduced risk of hydration in the silo
  • Easier discharge of the silos
  • Optimum cement granulometry (reduced quantity of “over-milled” particles)
  • Increased early and final strengths
  • Improved final strengths
  • Allows economic cement design with clinker replacements
  • Reduced water demand
  • Uniform air entrainment in the stated dosage range
  • Consistent setting times
  • Reduced brown or yellow discolorations
