Sika® ViscoCrete®-100 TS
HIGH PERFORMANCE SUPERPLASTICIZER FOR PRECAST CONCRETE
Sika® ViscoCrete®-100 TS is a third generation superplasticizer for high performance concrete particularly formulated for the production of precast elements, targeting its special demands regarding slump retention, very low water/binder ratios, use of double or triple blend mixes (cement, GGBFS, PFA and/or microsilica) and high degree of compaction.
Sika® ViscoCrete®-100 TS is especially suitable for use in Steel Fiber Reinforced Concrete (SFRC) and concrete mixes containing polypropylene fibers for fire protection as commonly used in precast concrete tunnel segment production.
Suitable for use in hot and tropical climatic conditions.
Sika® ViscoCrete®-100 TS works as a powerful superplasticizer and acts by different mechanisms. Through surface adsorption and steric hinderance effects separating the binder particles which results in higher dispersion, Sika® ViscoCrete®-100 TS allows the possibility to work with very low water/binder ratios by avoiding the high stickiness common to such kinds of mix. The following properties are achieved:
- Easier to control during casting due to sufficient retention period and high early strength development
- Extremely high water reduction (resulting in high density and strengths) even in double or triple blend mixes (e.g. cement, GGBS, and silica fume)
- Low w/b ratio leads to very low water permeability, and chloride migration
- Increased high early strength and strength development even with the use of low cement content mixes
- Improved shrinkage and creep behavior
- Excellent flow ability resulting in minimal placing and compacting efforts leading to much denser concrete
- Does not contain chlorides or other steel corrosion promoting ingredients therefore may be used for reinforced and pre-stressed concrete construction
