Sika® Stabilizer-4 R

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.


  • 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
