CHRYSO®Optima 238S

High Range Water Reducing Admix

CHRYSO®Optima 238S is a new generation high range water reducing admixture based on patented CHRYSO® phosphonate technology.

CHRYSO®Optima 238S is formulated specifically to maintain long workability retention and decrease mix stickiness for superior placeability and finishing.



CHRYSO®Optima 238S exclusive technology allows for extreme easiness of use, low viscosity and robustness.

CHRYSO®Optima 238S enables the production of self-levelling/ flowable concrete.



Application domain

  • Self Compacting Concrete

CHRYSO®Optima 238S is recommended for all concrete mixes where water content, improved cementitious material performance , high workability retention and very high strengths characteristics are desirable.


  • White cement
  • All cement types
  • Ready-mix concrete
  • Piles
  • High performance Concrete – Very High Performance Concrete – Ultra High Performance Concrete


  • CHRYSO®Optima 238S allows concrete with an important workability to be obtained, while reducing strongly the water/cement ratio.
  • Enhances the workability retention of concrete particularly inhot climates.
  • The dispersion properties of CHRYSO®Optima 238S allow the user to optimise the cement content when a specified mechanical strength is required.
