SikaGrind-769 VN

EFFICIENT GRINDING AID AND PERFORMANCE ENHANCER FOR THE CEMENT

SikaGrind-769 VN is a chloride-free liquid cement grinding aid with performance enhancing properties. SikaGrind-769 VN VN has been specifically designed to increase the output of cement grinding plants and obtain improved strength development for cements with high amount of clinker replacements.

SikaGrind-769 VN is a dispersant with the following characteristics:
  • Neutralisation of electrical charges on the surface of the cement particles
  • Separation of the cement particles
  SikaGrind-769 VN 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 increased output of the grinding system (tons per hour).
  • 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-769 VN gives the following advantages to the finished cement:
  • Reduced quantity of “over-milled” particles in the cement granulometry
  • Easier discharge of the silos
  • Increased strengths
  • Economic cement design with clinker replacements
  • Improved slump retention of concrete
