Sika® Plastiment® RX

Sika® Plastiment® RX is a new generation, synthetically manufactured, set-retarding, final strength increasing admixture for concrete. Sika® Plastiment® RX provides for a more plastic and flowable concrete, greater uniformity, increased durability, reduced shrinkage and permeability in your concrete. Sika® Plastiment® RX facilitates placing and finishing by providing controlled retardation of the concrete’s setting time, preventing premature stiffening.

  • Controlled retardation (determined by dosage).
  • Increased workability and easier placeability.
  • Easier and faster pumping of concrete.
  • Improved finishing characteristics for flatwork.
  • Reduced shrinkage and cracking.
  • Reduced segregation at a given slump.
  • Greater impermeability.
  • Increased concrete durability and uniformity.
  • Improved appearance of architectural concrete.
  • Increased strength at final ages.
