CHRYSO®Delta 15S

Set retarding water reducing/ plasticizing admixture

CHRYSO®Delta 15S 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.

CHRYSO®Delta 15S has no surface tension effects. Its use in concrete modifies in no way the consistency of concrete.

CHRYSO®Delta 15S can be used simultaneously with high range water reducing superplasticizers.

Application domain

  • All cement types
  • Workability retention
  • Ready-mix concrete


  • CHRYSO®Delta 15S is used to adjust the workability retention and initial workability being fine-tuned thanks to the ultra / high range water reducing admixture.
  • CHRYSO®Delta 15S can therefore be used for a wide range of concretes.
  • CHRYSO®Delta 15S is the perfect solution in case of remote jobsite or heavy traffic, as well as temperature changes.
  • CHRYSO®Delta 15S makes it possible to avoid re-tempering at the delivery point.
  • CHRYSO®Delta 15S is particularly suited for cements for which workability retention is difficult to get and/or at high temperature.
