Stabilised Superplasticiser for Precast Concrete Production

Sika® ViscoCrete®-7160 is a liquid high performance superplasticiser and viscosity modifying admixture providing improved rheology and robustness to high workability concretes. Sika® ViscoCrete®-7160 is based on polycarboxylate polymers.

  • High-range water reductions resulting in higher strengths and densities
  • Improved cohesion properties in highly fluid concrete or SCC
  • Improved durability
  • Improved early and ultimate strengths
  • Optimal rheology properties for SCC production
  • Reduced segregation and bleeding
  • Reduced drying shrinkage
  • Improved consistence retention
  • Improved surface finish
Usage
  • Sika® ViscoCrete®-7160 is a unique product that is suitable for the production of precast concrete
  • High performance concrete
  • Self-compacting concrete
  • Concrete requiring high early strength

Technical Information
Specific Advice

Air Entrainment: Negligible, normally minimal increase
Effect on Setting: Minimal effect
Effect of Overdosing: Increased workability and segregation
Application Information
Dispensing

Sika® ViscoCrete®-7160 is added to the gauging water or added with it into the concrete mixer.
To take advantage of the high water reduction, a wet mixing time, which is depending on the mixing conditions and mixer performance, of at least 60 seconds is recommended.
Compatibility

Sika® ViscoCrete®-7160 may be combined with many other Sika products.
