Sika® Plastocrete® WR-2 Plus

New generation water reducing admixture

Sika® Plastocrete® WR-2 Plus is recommended for use in the production of conventional ready mixed concrete, whenever increased plasticity and higher ultimate strengths are desired.

The use of Sika® Plastocrete® WR-2 Plus provides the following benefits in concrete:
  • Improved workability
  • Improved compressive and flexural strength
  • Allows optimisation of cement content
  • Improved finishability
  • Improved durability
Sika® Plastocrete® WR-2 Plus does not contain intentionally added chlorides and will not initiate nor promote the corrosion of steel in the concrete.

Application

Application Information

Dispensing

  • For best plasticizing results, Sika® Plastocrete® WR-2 Plus should be added directly to freshly mixed concrete in the concrete mixer at the end of the batching cycle
  • Sika® Plastocrete® WR-2 Plus may also be dispensed as an integral material during the regular admixture batching cycle, or into freshly mixed concrete in a Ready-Mix truck at the concrete plant or job site 
  • To optimize the plasticizing effect, Sika recommends that the combined materials be mixed for 80-100 revolutions, either in the concrete mixer or in the Ready-Mix truck
Consumption

Recommended Dosage

Dosage rates will vary depending on the material used, ambient conditions and the requirements of a specific project. For general concreting applications, Sika recommends a dosage rate between 300-800 ml/100 kg of cementitious materials for normal water reduction and setting characteristics. Dosage rates outside the recommended range may be used where specialized materials such as SikaFume® are specified, extreme ambient conditions are encountered or unusual project conditions require special consideration.
