CHRYSO®Tard CE is classified as a set retarding water reducing/plasticising admixture according to SANS 50934-2:2011 (EN 934-2:2009). The admixture thus induces the following major effects on a concrete mix: 

  • Produces the combined effects of a high range reducing/plasticising admixture (primary function) and
  • A set retarding admixture (secondary function).
  • Water reduction significantly improves compressive strengths at all ages.
  • CHRYSO®Tard CE allows strength grades to be met at reduced cement content or increased workability.  
  • Water reduction enhances durability through production of low permeability concrete.
  • Controlled retardation extends the working life and the stiffening time for ease of construction, minimising delay problems.
  • Control of stiffening improves slip forming and assists in preventing the formation of cold joints in large pours.
  • Chloride free, safe for use in pre-stressed and reinforced concrete.
Domains of application
  • Suitable with all types of Portland cement.
  • Semi-dry concrete screeds.
  • Mixes containing fly ash, slag and silica fume.
  • Reinforced or pre-stressed concrete.
  • Transport of concrete over long distances.
