Efficient grinding aid for the production of cement

SikaGrind®-870 is a chloride free liquid cement grinding aid with performance enhancing properties. SikaGrind®-870 has been specifically designed to increase the output of cement grinding plants and obtain improved early strength development for cements with high amount of clinker replacements.

SikaGrind®-870 is a dispersant with the following characteristics:
  • Neutralisation of electrical charges on the surface of the cement particles
  • Separation of the cement particles
SikaGrind®-870 provides the following advantages in the cement production:
  • Enhanced grinding properties of the cement mill due to less accumulation of material on grinding balls and mill-liners
  • Higher separator efficiency due to improved cement particle dispersion
  • Reduced relative power consumption per ton of cement due to SikaGrind®-870 is a dispersant with the following characteristics
  • Easier achievement of the desired cement fineness (Blaine, particle fraction > 32μm, granulometry) due to reduced re-agglomeration of the sufficiently ground cement particles
  • Minimized problems with “plugging” due to improved powder flow characteristics
SikaGrind®-870 gives the following advantages to the finished cement:
  • Reduced quantity of “over-milled” particles in the cement granulometry
  • Easier discharge of the silos
  • Increased early strengths after 1 and 2 days
  • Economic cement design with clinker replacements
