Sika® Stabilizer-300 SCC

Viscosity Modifying Admixture

Sika® Stabilizer-300 SCC is a ready to use liquid-based viscosity modifying admixture recommended for production of Self Consolidating Concrete where high flow and improved cohesiveness of the concrete mix design are required. Sika® Stabilizer-300 SCC increases the stability and finishability of concrete. Sika® Stabilizer-300 SCC is compatible with Sika® ViscoCrete® and Sikament® high range water reducing admixtures. Sika® Stabilizer-300 SCC helps stabilize the air void system in fresh concrete. Sika® Stabilizer-300 SCC is recommended for precast and ready mix concrete applications. Sika® Stabilizer-300 SCC conforms to the requirement of ASTM C 494 / AASHTO M 194, Type S admixture.

  • Improves concrete finishability with no impact on set time
  • Enhances stability of concrete mix & helps mitigate impacts of material changes
  • Increase the cohesiveness of lean and harsh mix designs

Usage

Sika® Stabilizer-300 SCC increases mix cohesiveness viscosity characteristic of concrete. Sika® Stabilizer-300 SCC produces concrete that becomes fluid and flowable when sheared or mechanically agitated. This characteristic enables concrete to flow easily through and into confined spaces. The mix will revert to a dense, high viscous consistency when at rest. This cohesive cement paste matrix promotes high compressive and flexural strength development. Sika® Stabilizer-300 SCC is not an Anti- Washout Admixture. For underwater concreting applications use Sikament®-100 SC.    Sika® Stabilizer-300 SCC is suitable for usage in cases when:
  • Higher viscosity 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
  • An Architectural Precast application is required
  • Minimizing the effect of fluctuation of water content in aggregates

Advantages

  • Enhances stability of the concrete mix during high slump or SCC placement.
  • Improves distribution of aggregate within the concrete mixture
  • Increases the cohesiveness of lean and harsh mix designs
  • Reduces segregation and bleeding
  • Decreases pumping pressures
  • Improves surface finishability
  • Improves long term compressive strength

Packaging

Sika® Stabilizer-300 SCC is available in 5 gallon (19 liters) pails, 55 gallon (208 liters) drums, 275 gallon (1040 liters) totes and bulk delivery.

Application

Application Information

Mixing

Sika® Stabilizer-300 SCC should be added to the fresh concrete after all other mix ingredients have been blended together. Addition of the Sika® Sika® Stabilizer-300 SCC 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® Stabilizer-300 SCC may result in a concrete mix that is more likely to bleed or separate. Sika® Stabilizer-300 SCC 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.

  

Sika® Stabilizer-300 SCC is compatible with all other Sika admixtures. All the admixtures must be dispensed separately into the concrete mix.
Consumption

Recommended Dosage

Sika® Stabilizer-300 SCC is formulated for use at a rate of 0.3–4 fl. oz / 100 lbs (20–240 ml / 100 kg.) of cementitious content. The amount of Sika® Stabilizer-300 SCC must be proportionately increased as water content increases and may be reduced with lower water content.
