SikaGrind®-721

GRINDING AID AND QUALITY IMPROVER FOR THE PRODUCTION OF CEMENT

SikaGrind®-721 is a liquid additive with strength-enhancing properties. SikaGrind®-721 has been specifically developed to obtain cements with strongly increased early and final strength.

SikaGrind®-721 provides the following advantages in the cement production:
  • Less accumulation of material on grinding equipment (grinding balls and mill)
  • Higher efficienty of the plants (tons per hour) due to reduced grinding time per ton
 
  • Higher separator efficiency due to improved dispersion
  • Easier achievement of the desired cement fineness
  • Cost savings due to lower power consumption per ton
SikaGrind®-721 gives the following advantages to the finished cement:
  • Increased early and final strength
  • Improved powder flow characteristics and easier discharge of silos

Application Information

Compatibility

Cements treated with SikaGrind®-721 are compatible in concretes produced with all commercial admixtures, including air entrainers, water reducers, retarders and superplasticizers. The performance of concrete admixtures are not adversely affected by the use of SikaGrind®-721.
Consumption

Recommended Dosage

Typical dosage rates of SikaGrind®-721 are between 0.2-0.5 kg per tonne of cement (0.02-0.05 % 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 plant trials according to the desired properties of the cement. For consistent results, SikaGrind®-721 must be accurately dispensed.
