CP-K / Binding Retardant Additive


  • The additive increases the time required for the mixture to transition from the plastic state to the solid state;
  • Has plasticizing qualities;
  • Delays the onset of binding by 90-120 min. compared to the control mixture;
  • Delays the binding end time by 360 min. compared to the control mixture;
  • Binding strength after 7 days – 80-90% of the control mixture;
  • Binding strength after 8 days ≥ 90% of the control mixture.


  • For ready-mixed concrete and mixtures that need to be transported;
  • Can be used for tense reinforced concrete structures;
  • At low air temperatures, the onset of binding slows down.
