CHRYSO®Tard 100S

Set retarding admixture

CHRYSO®Tard 100S slows down the hydration of cement by momentarily blocking the surface of the cement particles. At the end of setting, the concrete hardens rapidly and higher compressive strength is obtained after 28 days. It is suitable for roller compacted concrete structures

CHRYSO®Tard 100S has no surface tension effects. Its use in concrete modifies in no way the consistency of concrete.

CHRYSO®Tard 100S can be used simultaneously with high range water reducing superplasticizers.

Application domain

  • All cement types
  • Plastic or fluid concretes
  • Concrete with workability retention
  • Precast elements
  • Dams
  • Ready-mix concrete
  • Piles
  • Prestressed concrete


CHRYSO®Tard 100S is used to adjust the workability retention and initial workability being fine-tuned thanks to the ultra / high range water reducing admixture.

CHRYSO®Tard 100S can therefore be used for a wide range of concretes.

CHRYSO®Tard 100S is the perfect solution in case of remote jobsite or heavy traffic, as well as temperature changes.

CHRYSO®Tard 100S makes it possible to avoid re-tempering at the delivery point.

CHRYSO®Tard 100S is particularly suited for cements for which workability retention is difficult to get and/or at high temperature.
