SikaGrind®-190 Activator

Grinding aid and quality improver for early and final strengths

SikaGrind®-190 Activator is a liquid additive to allow easier grinding of cement and enhance the quality of all types of cement. SikaGrind®-190 Activator has been specifically developed to obtain cements with strongly increased early and final strengths.

SikaGrind®-190 Activator is a very effective dispersant with the following characteristics:
  • Neutralisation of electrical charges on the surface of the cement particles
  • Separation of the cement particles
SikaGrind®-190 Activator provides the following advantages in the cement production:
  • Higher efficiency of the plants (tons per hour) due to reduced grinding time per ton
  • Higher separator efficiency due to improved dispersion
 
  • Faster achievement of the desired cement fineness
  • Reduced particle fraction > 32µ of the ground cement
  • Reduced re-agglomeration of the cement particles
  • Less accumulation of material on grinding equipment (grinding balls and mill)
  • 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®-190 Activator gives the following advantages to the finished cement:
  • Reduced handling costs especially on pneumatic conveying systems
  • Reduced risk of hydration in the silo
  • Easier discharge of the silos
  • Optimum cement granulometry (reduced quantity of “over-milled” particles)
  • Increased early strengths
  • Improved final strengths
  • Allows economic cement design with clinker replacements
  • Reduced water demand
  • Uniform air entrainment in the stated dosage range
  • Consistent setting times
  • Reduced brown or yellow discolorations

Application

Application Information

Dispensing

SikaGrind®-190 Activator is added into the grinding mill (first or second compartment), onto the clinker feeding channel or sprinkled / dropped onto the clinker (raw material) on the conveyor belt. Suitable dosage pumps with adjustable flow rates should be used for accurate dosing.

Note: Periodically, the end of the additive tube should be checked to ensure, that it is not blocked with cement clinker/dust.

Compatibility

Cements treated with SikaGrind®-190 Activator are compatible in concretes produced with all commercial admixtures including air entrainers, water reducers, retarders and superplasticizers. Performance of concrete admixtures are not adversely affected by use of SikaGrind®-190 Activator.
Consumption

Recommended dosage

Typical dosage rates of SikaGrind®-190 Activator are between 0.2 – 1.0 kg per tonne of cement (0.02% - 0.1% 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®-190 Activator must be accurately dispensed.
