Sika® SR Stabilizer-3200

VISCOSITY MODIFYING ADMIXTURE

Sika® SR Stabilizer-3200 is a ready to use liquid-based viscosity modifying admixture.
Sika® SR Stabilizer-3200 improves stability and segregation resistance of concrete mixes without significant reduction of slump or flow, resulting in improved surface quality and aesthetics. Sika® SR Stabilizer-3200 is suitable for various types of concrete. Sika® SR Stabilizer-3200 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® SR Stabilizer-3200 helps stabilize the air void system in freshly mixed and placed concrete and increases the overall concrete stability. Sika® SR Stabilizer-3200 also reduces the consolidation effort, which could be utilized in a dry-cast application to reduce the production cycle time. Sika® SR Stabilizer-3200 is compatible with Sika ViscoCrete high range water reducing admixtures and is recommended for precast and ready mix concrete applications.
Sika® SR Stabilizer-3200 meets the requirements for ASTM C-494, Type S admixture.

Sika® SR Stabilizer-3200 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

Usage

Sika® SR Stabilizer-3200 is suitable for usage in cases when:
  • Higher resistance to segregation is required
  • Improved stability during transportation is required
 
  • Lean concrete mix designs are used for SCC production
  • 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
  • Faster concrete consolidation is required

Technical Information

Concrete Mix Design

Sika® SR Stabilizer-3200 should be added to the fresh concrete after all other mix ingredients have been blended together. Addition of the Sika® SR Stabilizer-3200 directly into the concrete too early may promote clumping of the mix materials.
For best results, the concrete should be prepared in a concrete mixer that can thoroughly shear the materials and blend all of the components. Turbine mixers and central mix plants often perform better than dry batched transit mixers.
Insufficient mixing or use of less than recommended quantities of Sika® SR Stabilizer-3200 may result in a concrete mix that is more likely to bleed or separate. Sika® SR Stabilizer-3200 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 1 minute/cu. yd or at least 5 minutes.

Application

Consumption

Recommended Dosage

Dosage rates will vary according to materials used, ambient conditions and the requirements of a specific project. Sika recommends dosage at 1.0 - 7 fl.oz/100 lbs. (65-455 ml/100kg) of cementitious materials. Dosage rates outside the recommended range may be used where specialized materials such as microsilica are specified, extreme ambient conditions are encountered or unusual project conditions require special consideration. In this case please contact Technical Service Department.
The amount of Sika® SR Stabilizer-3200 must be proportionately increased as water content increases and may be reduced with lower water content.
To determine proper dosage, site trials with local materials are always recommended.
In case of overdosing, retardation and concrete stiffness can occur. In such a case, increase dosage of HRWR to maintain desired consistency.
