CHRYSO® Slump Minus

Viscosity Modifying Admixture

Description

Slump Minus is a high-performance liquid admixture designed to enhance the rheological properties of concrete. This viscosity-modifying admixture significantly improves the stability and segregation resistance of various concrete mixes, including self-consolidating concrete (SCC), high-slump conventional mixes, and those containing manufactured or poorly graded aggregates.

 

Slump Minus stabilizes the air void system within the concrete matrix, promoting enhanced durability. 

Slump Minus achieves these benefits without compromising workability, maintaining slump and flow characteristics essential for efficient placement and finishing. The result is a superior concrete product with enhanced surface quality, aesthetics, and plastic properties. 

Application areas

Slump Minus is ideal for enhancing concrete performance in various scenarios, including:

  • Projects requiring faster consolidation: Reduces the time and effort needed for concrete consolidation, improving efficiency.
  • Concrete during transportation: Maintains consistency and workability, minimizing slump loss and segregation risks.
  • Low slump concrete: Improves flowability and aesthetics for easier placement and a smoother finish.
  • Concrete prone to segregation: Increases cohesiveness and stability to prevent separation of aggregates and paste.
  • Manufactured sand and gap-graded aggregates: Addresses challenges associated with these materials, improving workability and stability.
  • Inconsistent aggregate moisture: Compensates for fluctuations in moisture content, ensuring consistent concrete production.
  • Lean concrete mix designs (SCC): Enhances workability and cohesiveness for easier placement and self-consolidation.
  • Concrete with air migration issues: Stabilizes air voids, leading to a more uniform and stable mix.

Benefits

  • Enhanced Stability: Preserves the integrity of the concrete matrix, even under high-slump conditions.
  • Increased Cohesiveness: Optimizes the workability of both lean and harsh mix designs.
  • Reduced Consolidation Effort: Requires less energy and time for compaction due to improved workability.
  • Improved Aggregate Distribution: Ensures a homogeneous dispersion of aggregates throughout the mixture.
  • Reduced Segregation and Bleeding: Minimizes the separation of constituent materials, enhancing overall quality and durability.
  • Optimized Air Void Distribution: Enhances the durability and freeze-thaw resistance of the concrete.
  • Improved Surface Finishability: Facilitates achieving a smooth and uniform surface finish.
