Set retarding admixture

CHRYSO®Tard CHR slows down cement hydration by momentarily blocking the surface of the cement particles. At the end of setting, concrete hardens rapidly and high compressive strength are obtained after 28 days. CHRYSO®Tard CHR has no surface tension effects.

Its use in concrete does not modify the consistency of concrete in any way. CHRYSO®Tard CHR can be used simultaneously with high range water reducing superplasticizers.

Application domain

  • All cement types
  • Hot weather concreting
