SikaGrind®-511 (TH) HYC

Efficient grinding aid and quality improver for hydraulic cement

SikaGrind®-511 (TH)-HYC is a liquid cement grinding aid with performance enhancing properties. SikaGrind®-511 (TH)-HYC has been specifically designed to increase the output of cement grinding mill and obtain improved all age strength development for mortar and concrete.

SikaGrind®-511 (TH)-HYC is a dispersant with the following characteristics:
  • Neutralisation of electrical charges on the surface of the cement particles
  • Reduced agglomeration of ground cement particles (better dispersion)
  • Less coating (accumulation of material) on grinding media and mill internals
  SikaGrind®-511 (TH)-HYC 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®-511 (TH)-HYC gives the following advantages to the finished cement:
  • Reduced quantity of “over-milled” particles in the cement granulometry
  • Easier discharge of the silos
  • Increased all age strength of mortar and concrete
  • Economic cement design with clinker replacements

Application Information

Compatibility

Cements treated with SikaGrind®-511 (TH)-HYC are compatible in con­cretes produced with all commercial admixtures including air entrainers , water reducers, retarders, and super plasticizers. The performance of con­crete admixtures is not adversely affected by the use of SikaGrind®-511 (TH)-HYC.

Dispensing

SikaGrind®-511 (TH)-HYC 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®-511 (TH)-HYC are between 0.3 - 0.6 kg per ton of cement (0.03% - 0.06% of total weight = cement clinker + additions). The optimum dosage, which changes according to the properties of each clinker source, type of cement, and other plant variables, should be determined in the plant trials according to the desired properties of the cement.

For consistent results, SikaGrind®-511 (TH)-HYC must be accurately dispensed.
