SikaGrind®-180 MY

Grinding aid and quality improver for the production of cement

SikaGrind®-180 MY is a liquid cement grinding aid with performance enhancing properties. SikaGrind®-180 MY has been specifically designed to obtain cements with strongly increased early and final strengths.

SikaGrind®-180 MY is a dispersant with the following characteristics:
  • Neutralisation of electrical charges on the surface of the cement particles
  • Separation of the cement particles
SikaGrind®-180 MY 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 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®-180 MY 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

Compatibility

Cements treated with SikaGrind®-180 MY 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®-180 MY.

DISPENSING

SikaGrind®-180 MY 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.

 

Consumption

Recommended dosage

Typical dosage rates of SikaGrind®-180 MY 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 desired properties of the cement.

For consistent results, SikaGrind®-180 MY must be accurately dispensed.
