SikaGrind®-739 VN
EFFICIENT GRINDING AID AND PERFORMANCE ENHANCER FOR THE CEMENT
SikaGrind®-739 VN is a chloride-free liquid cement grinding aid with performance enhancing properties.
SikaGrind®-739 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®-739 VN is a dispersant with the following characteristics:
- Neutralisation of electrical charges on the surface of the cement particles
- Separation of the cement particles.
- 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.
- 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.
