Sika® Retarder-22

Set Retarding Concrete Admixture

Sika® Retarder-22 is a phosphate based liquid admixture that slows the cement hydration; delaying the initial set in direct proportion to the dosage used. After the planned delay in initial set, hardening develops at an accelerated rate. Suitable for use in tropical and hot climatic conditions.

Sika® Retarder-22 provides the following:
  • Controlled setting time
  • Safety: Sika® Retarder-22 merely retards and does not “kill” the set of cement
  • Does not entrain air even at high dosages
