Product Definition

CAST CT 789 is a chemical admixture which, without affecting the consistency, permits a high reduction in the water content of a given concrete, or which, without affecting the water content, increases the slump/flow considerably, or produces both effects simultaneously.


CAST CT 789 is recommended for use in the applications and purposes below
  • For improving workability and placing of conventional fresh concrete.
  • For improving placing of concrete designed for slabs.
  • Ready-mixed concrete production
  • Normal reinforced concrete elements such as column, shear wall and beam.
  • concrete work requiring early formwork removal.

Advantages and Properties

  • CAST CT 789 is a modified polymer based, general purpose chemical admixture designed for improving workability of fresh concrete without increasing water content.
  • CAST CT 789 increases the flowability of fresh concrete without causing segregation.
