Sika® Plastocrete®-901

Water -Reducing and Retarding Concrete Admixture

A liquid plasticizing admixture acts as a retarder on setting time for freshed concrete. A water reduction can be achieved without loss of workability even in hot climate.

Plastocrete® -901 provides the following properties:
  • Increased setting times at elevated temperatures
  • Longlasting control of slump loss
  • Improved workability without increased water content
  • Reduced water without loss of workability
  • Increased strengths
  • Reduced shrinkage and creep
  • Improved surface finish
  • Chloride-free does not attack reinforcement
