SikaGrind®-180 KE

Strength enhancing grinding aid for the production of cement

SikaGrind®-180 KE is a liquid cement grinding aid with performance enhancing properties designed to increase the output of cement grinding plants and obtain improved strength development for cements.

SikaGrind®-180 KE 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 KE 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 and improved powder flow characteristics.
SikaGrind®-180 KE gives the following advantages to the finished cement:
  • Reduced quantity of “over-milled” particles in the cement granulometry and easier discharge of the silos
  • Increased early strengths and economic cement design with clinker replacements

Application

Application Information

Compatibility

Cements treated with SikaGrind®-180 KE 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 KE. 

DISPENSING

SikaGrind®-180 KE 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®-180 KE is between 0.5–2.0 kg per tonne of cement (0.05–0.20 % of total weight = cement clinker + additions). Prior plant trials are necessary to determine optimum dossage because of variables such as clincker properties, cement type, and others
