SikaGrind®-8710

Efficient grinding aid & performance enhancer for cement

SikaGrind®-8710 is a chloride free liquid cement grinding aid with performance enhancing properties. SikaGrind®-8710 has been specifically designed to increase the output of cement grinding plants and obtain improved strength development for cements at all ages.

SikaGrind®-8710 is a dispersant with the following characteristics:
  • Neutralisation of electrical charges on the surface of the cement particles, reducing agglomeration of ground cement particles (better dispersion)
  • Less coating (accumulation of material) on grinding media and mill internals
SikaGrind®-8710 provides the following advantages in the cement production:
  • Enhanced grinding performance of the cement mill
  • Higher separator efficiency
  • Higher mill output (tons per hour)
  • Reduced relative power consumption per ton of cement
  • Easier achievement of the desired cement fineness (Blaine, particle fraction > 45μm, granulometry)
  • Minimized problems with “plugging” due to improved powder flow characteristics
SikaGrind®-8710 gives the following advantages to the finished cement:
  • Reduced quantity of “over-milled” particles in the cement granulometry
  • Easier discharge of the silos
  • Increased strength development at all ages
  • Economic cement design with clinker replacements

Application

Application Information

Compatibility

Cements treated with SikaGrind®-8710 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®-8710.

Dispensing

SikaGrind®-8710 shall be 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

For consistent results, SikaGrind®-8710 must be accurately dispensed. Typical dosage rates of SikaGrind®-8710 are between 0.2 to 0.6 kg per tonne of cement (0.02% - 0.06% of total weight of cement clinker and additions). The optimum dosage to achieve the desired characteristics shall be determined in plant trials. Influencing factors include the properties of clinker source, type of cement and other plant variables.
