Sika® Retarder IQ

Set retarding admixture

Sika® Retarder IQ is a highly efficient retarding admixture which delays the initial setting time of concrete.

  1. Reduces the rate of hydration of cement and controls concrete temperature.
  2. Improves slump retention and retards set time of concrete.
  3. Provides sufficient time for placement and finishing of concrete without cold joints in hot weather conditions.
  4. In mass concrete pours, Sika® Retarder IQ controls temperature rise and reduces the risk of thermal cracking.
