SikaGrind®-196 (VN)

Efficient grinding aid for the production of cement

SikaGrind®-196 (VN) is a chloride free liquid cement grinding aid with performance enhancing properties.
SikaGrind®-196 (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®-196 (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®-196 (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 reagglomeration of the sufficiently ground cement particles;
  • Minimized problems with “plugging” due to improved powder flow characteristics.
SikaGrind®-196 (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 at all ages;
  • Economic cement design with clinker replacements;
  • Reduced water for normal consistency.

Application Information

Compatibility

Cements treated with SikaGrind®-196 (VN) are compatible in concretes produced with all commercial admixtures including air entrainers, water reducers, retarders and superplasticizers. The performance of concrete admixtures is not adversely affected by the use of SikaGrind®-196 (VN).

DISPENSING

SikaGrind®-196 (VN) is added onto the clinker feed shortly before the mill entrance or directly into the grinding mill (first or second compartment). Suitable dosage pumps with adjustable flow rates shall be used for accurate dosing.

Note: Periodically, the end of the additive tube/hose shall be checked to ensure that it is not blocked!
Consumption

Recommended Dosage

Typical dosage rates of SikaGrind®-196 (VN) are between 0.5–1.5 kg per tonne of cement (0.05%–0.15% of total weight = cement clinker + additions). The optimum dosage to achieve the desired characteristics shall be determined in Plant trials. Influencing factors are e.g. the properties of clinker source, type of cement and other plant variables. For consistent results, SikaGrind®-196 (VN) must be accurately dispensed.
