Sika® ViscoCrete®-7160

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

Effect on Setting: Minimal effect
Effect of Overdosing: Increased workability and segregation

Application

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.
Important: Always conduct trials before combining products in specific mixes and contact our Technical Service Department for information and
advice about any specific combinations.
Consumption

Recommended Dosage

0.3–1.5 % by weight of cement
