SikaGrind®-201 EXP KE

Strength enhancing grinding aid 

SikaGrind®-201 EXP KE is a chloride free grinding aid for portland cement and other hydraulic cements. SikaGrind®-201 EXP KE is designed to improve the efficiency of the grinding process, reduce the energy for grinding clinker, and enhance early strength development. 

SikaGrind®-201 EXP KE is a very effective dispersant with the following characteristics:
  • Reduction of the agglomeration forces on the particle surface
  • Reduction of the particle attraction
SikaGrind®-201 EXP KE provides the following advantages in the cement production:
  • Increases the efficiency of the separator, thanks to good dispersion
  • Required fineness is faster achieved
  • Reduced share of oversize particles
  • Lower coating of balls and mill interior with cement Lower specific grinding energy (kWh/t) thereby enhancing cost reduction
  • Improved powder flowability and easier handling
SikaGrind®-201 EXP KE gives the following advantages to the finished cement:
  • Reduced handling/transport cost, especially in air slide channel
  • Easy discharge of silos
  • Optimised particle distribution, less over-ground
  • Increased early and final mechanical strength
  • Can be used to reduce the clinker factor thus optimizing the economics of production costs.

Usage

SikaGrind®-201 EXP KE is used for cement grinding in order to:
  • Neutralization of electrical charges on the surface of the cement particles thus enhancing mill efficiency and productivity 
  • Separation of the cement particles.
  • Improve the cement quality

Application

Application Information

Dispensing

SikaGrind®-201 EXP KE is added onto the clinker feed shortly before the mill entrance or directly into the grinding mill. 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!

Compatibility

Cements treated with SikaGrind®-201 EXP KE 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®-201 EXP KE.
Consumption

Recommended dosage

The typical dosage rate of SikaGrind®-201 EXP KE is 0.4 – 1 kg per tonne of cement (0.04-0.1 % of total weight = cement clinker + additions). The optimum dosage to achieve the desired characteristics shall be determined in plant trials. Influencing factors are e.g. the properties of clinker, SCM and other plant variables. For consistent results, SikaGrind®-201 EXP KE must be accurately dispensed.
