CHRYSO®Quad 850S

New Generation, high range water reducing/ superplasticizing admixture

CHRYSO®Quad 850S is a new generation superplasticizer with very high-water reduction capability based on latest molecular synthesis technology from CHRYSO ® Synthesis Molecules.

CHRYSO®Quad 850S has been developed for fine aggregates that have high clay/silt content, and to maintain fresh concrete that helps to keep enough slump retention, which is not possible with a normal admixture. It can be used also with normal sands and aggregates.

Thanks to its specifically designed molecular structure, CHRYSO®Quad 850S enables the concrete manufacturer to produce cohesive, low viscous concrete and long workability retention.

CHRYSO®Quad 850S enables the production of flowable/self-leveling concrete.

Application domain

  • All cement types
  • Ready-mix concrete
  • Reinforced concrete
  • High Performance Concrete – Very High Performance Concrete


  •  CHRYSO®Optima 850S 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®Quad 850S allow the user to optimise the cement content when a specified mechanical strength is required.
