Sika® Stabilizer-4 R AU

Viscosity Modifying Admixture

Sika® Stabilizer-4 R AU is a ready to use liquid-based viscosity modifying admixture. Sika® Stabilizer-4 R AU improves stability and segregation resistance of concrete mixes without significant reduction of slump or flow, resulting in improved surface quality and aesthetics. Sika® Stabilizer-4 R AU is suitable for various types of concrete. Sika® Stabilizer-4 R AU 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-4 R AU helps stabilize the air void system in freshly mixed and placed concrete and increases the overall concrete stability.  Sika® Stabilizer-4 R AU is compatible with Sika® ViscoCrete® high range water reducing admixtures and is recommended for precast and ready mix concrete applications. 

Sika® Stabilizer-4 R AU 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
  • Increases the cohesiveness of lean and harsh mix designs
  • Reduces segregation and bleeding
  • Improves surface finishability
