CHRYSO®Optima 245S

High range water reducing Super plasticizing admixture

CHRYSO®Optima 245S is a new generation superplasticizer with very high water reduction capability based on modified polycarboxylate and synthetic polymers.

Thanks to its specifically designed molecular structure, CHRYSO®Optima 245S enables the concrete manufacturer to produce cohesive, low viscous concrete with long workability retention and low air content.

CHRYSO®Optima 245S has been developed to maintain fresh concrete workability without compromising the setting time.

CHRYSO®Optima 245S enables the production of self-leveling concrete.

Application domain

  • All cement types
  • Self consolidating concrete
  • Workability retention
  • Ready-mix concrete
  • High strength performance


  • CHRYSO®Optima 245S allows concrete with an important workability to be obtained, while reducing strongly the water/cement ratio.
  • Enhances the workability retention of concrete particularly in hot climates.
  • The dispersion properties of CHRYSO®Optima 245S allow the user to optimise the cement content when a specified mechanical strength is required.


  • 20 L bucket
  • 200 L drum
