CHRYSO®Delta CQ 21

CHRYSO®Delta CQ 21 is a new generation superplasticizer based on modified polycarboxylate and synthetic polymers particularly recommended for ready-mix concrete and civil engineering construction sites.

Thanks to its specifically designed molecular structure, CHRYSO®Delta CQ 21 enables the concrete manufacturer to produce cohesive, low viscous concrete with long workability retention.

CHRYSO®Delta CQ 21 intends to create a high water reduction and/or an increased
period of workability retention. It allows the manufacture of concrete with a long
workability retention without prejudicial set-retarding effect. Thus, CHRYSO®Delta
CQ 21 may be used in a large concrete range.

CHRYSO®Delta CQ 21 is particularly adapted to homogeneous SCC formulation.

  • CHRYSO®Delta CQ 21 allows concrete with an important workability to be obtained, while reducing the water/cement ratio.
  • Enhances the workability retention of concrete in hot climates.
  • Improves concrete pumpability and finishing quality.
  • The dispersion properties of CHRYSO®Delta CQ 21 allow the user to optimise the cement content when a specified mechanical strength is required.
