High range water reducing/superplasticising concrete admixture with enhanced workability retention Sika ViscoFlow®-1000 is a liquid admixture for concrete based on unique polycarboxylate polymers technologies. Sika ViscoFlow®-1000 is designed as a high range water reducer or superplasticiser. It is particularly suited for use in concretes that require low water/cement ratios and / or high water reductions with excellent workability retention properties of up to 3 hours.
Sika ViscoFlow®-1000 meets the requirements of BS EN 934-2 table. - High range water reductions resulting in higher strengths and densities
- Extended consistence retention
- Improved cohesion properties
- Improved early and ultimate strengths
- Excellent placement characteristics
- Improved rheology
- Improved durability
- Reduced segregation and bleeding
- Reduced drying shrinkage
- Reduced mix costs
|
