Sika® Stabilizer-4 R

Sika®  Stabilizer  4R  is  a  ready  to  use  liquid-based  viscosity  modifying  admixture.  Sika®  Stabilizer  4R  improves  stability  and  segregation  resistance  of  concrete  mixes  without significant reduction of slump or flow, resulting in improved surface quality and aesthetics. Sika® Stabilizer 4R is suitable for various types of concrete. Sika® Stabilizer 4R  has  been  found  to  improve  plastic  properties  of  Self-Consolidating  Concrete  (SCC)  as  well  as  high  slump  conventional  concrete  mixes,  and  mixes  containing  manufactured sand and/or poorly graded aggregates.

Sika®  Stabilizer  4R  helps  stabilize  the  air  void  system  in  freshly  mixed  and  placed  concrete and increases the overall concrete stability. Sika® Stabilizer 4R also reduces the consolidation effort, which could be utilized in a dry-cast application to reduce the production  cycle  time.  Sika®  Stabilizer  4R  is  compatible  with  Sika®  ViscoCrete®  high  range  water  reducing  admixtures  and  is  recommended  for  precast  and  ready  mix  concrete applications.

Sika® Stabilizer 4R increases overall mix cohesiveness without promoting concrete stiffening, which ultimately results in easier placement, reduced consolidation effort and improved aesthetics.

  • Enhances stability of concrete matrix integrity during high slump placements.
  • Improves distribution of aggregate in the concrete mixture.
  • Increases the cohesiveness of lean and harsh mix designs.
  • Reduces segregation and bleeding.
  • Improves surface finishability.
  • Improves the air void distribution within the concrete matrix.
  • Reduces consolidation effort due to reduced stiffening.
