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

Usage

Sika® Stabilizer-4 R AU is suitable for usage in cases when:
  • Improved flow & aesthetics of low slump extruded concrete mixes
  • Higher resistance to segregation is required
  • Improved stability during transportation is required
  • Manufactured sand and/or “gap-graded” coarse aggregate is used
  • Migration of air within the concrete mixture is observed
  • Fluctuation of water content in aggregates causes inconsistent production

1.01 g/cm3 approximately

Application

Application Information

Dispensing

Sika® Stabilizer-4 R AU should be added to the fresh concrete after all other mix ingredients have been blended together. Addition of the Sika® Stabilizer-4 R AU directly into the concrete too early may promote clumping of the mix materials. Sika® Stabilizer-4 R AU may also be dispensed into freshly mixed concrete in a ready mix truck at the concrete plant or at the job site. When added on site, mixer should rotate its drum at maximum speed for a minimum of 2 minutes/m3.

Sika® Stabilizer-4 R AU should on no account be added to a dry mix.

Compatibility

Sika® Stabilizer-4 R AU can be used in conjunction with most of the Sika Concrete products, except Sika VMA . Trials are always recommended before use.
Consumption

Recommended dosage

Dosage rates will vary according to materials used, ambient conditions and the requirements of a specific project. Sika recommends dosage at 200–1500 ml/100 kg  of cementitious materials. Dosage rates outside the recommended range may be used where extreme ambient conditions are encountered or unusual project conditions require special consideration. In this case please contact your local Sales Representative   .
