SikaGrind®-299 (TH)

Grinding aid and quality improver for the production of cement and supplementary cementitious materials

SikaGrind®-299 (TH) is a liquid additive to allow easier grinding and quality enhancement of all types of cement and supplementary cementitious materials. SikaGrind®-200 has been specifically developed to obtain cements with increased early strengths.

SikaGrind®-299 (TH) is a very effective grinding aid 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®-299 (TH) provides the following advantages in the cement production:
  • Higher mill output (tons per hour)
  • Higher separator efficiency
  • Easier achievement of the desired fineness (specific surface, sieve residue)
  • Cost savings due to a lower power consumption per ton
  • Easier handling and minimized problems with “plugging” due to improved flow characteristics
  • Improved self-levelling of the cement in the silo
SikaGrind®-299 (TH) gives the following advantages to the finished cement:
  • Easier discharge of the silos
  • Optimum cement granulometry (reduced quantity of “over-milled” particles)
  • Increased early strengths
  • Allows economic cement design with clinker replacements
