Sikament®-512 star PK

High Range Water-Reducing and Set Retarding Concrete Admixture

Sikament®-512 star PK is used as a highly effective water-reducing agent and superplasticizer for the production of high quality, free flowing concrete in hot climates. The dual action of Sikament®-512 star PK promotes accelerated hardening with high early and ultimate strengths. Suitable for use in tropical and hot climatic conditions.

Sikament®-512 star PK provides the following properties:
As a Superplastiziser
  • Substantial improvement in workability without          increased water or the risk of segregation.
  • Long-lasting control of slump loss.
  • No adverse effect on ultimate strengths.
As a Water Reducer
  • Early strengths significantly increased.
  • High ultimate strengths.
  • Up to 20% water reduction.
  • Especially suitable for hot climates.
  • No excessive air-entrainment.
  • No adverse shrinkage effect.
  • Improved surface finish.
  • Increased water tightness.
