Sika® ViscoCrete® TS-100

Ultra-High Performance Superplasticizer for Precast Concrete & Semi-Dry Concrete Application

Sika® ViscoCrete® TS-100 is a third generation superplasticizer for high performance concrete. It was particularly formulated for the production of precast tunnel segments, targeting the high 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® TS-100is 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® TS-100 works as a powerful superplasticizer acts by different mechanisms. Through surface adsorption and steric hinderance effects separating the binder particles which results in higher dispersion 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

Usage

Sika® ViscoCrete® TS-100 facilitates extreme water reduction, with optimum cohesion and workability as required, just by adjusting the dosage. It is used mainly to the following types of concrete:
  • Precast concrete tunnel segments
  • Precast concrete in general
  • Pre-stressed concrete elements
  • Post-tensioned concrete bridge segments
  • Fast track concrete
  • In situ concrete that requires fast stripping time
  • Mixes containing Steel Fiber Reinforced Concrete (SFRC), synthetic fibers and polypropylene fibers for structural and / or fire resistant concrete
  • Concrete with high water reduction that requires high workability, slump retention along with high early strength development
  • Blocks and Interlocks

Technical Information

Concreting guidance

The standard rules of good concreting practice for production and placing must be observed when using Sika® ViscoCrete® TS-100 in concrete. Refer to relevant standards.
Fresh concrete must be cured properly especially at high temperatures in order to prevent plastic and drying shrinkage. Use Sika® Antisol® products as a curing agent or apply wet hessian.

Application

Application Information

Compatibility

Sika® ViscoCrete® TS-100 may be combined with all types of Portland cement and the following Sika products:
SikaPump®
Sika® FerroGard®-901
SikaFume®
SikaFiber®
Sika Aer®
Sika® Stabilizer
Sika®-1 WT
We recommend to perform trial mixes to establish the required performance when combined with the above products. Please consult our Sika Technical Department.

Dispensing

Sika® ViscoCrete® TS-100 is added to the gauging water or simultaneously poured with it into the concrete mixer at the batching plant.
Do not add Sika® ViscoCrete® TS-100 directly to the dry mix.
For optimum utilization of its high water reduction property we recommend thorough mixing at a minimal wet mixing time of 60 seconds. The addition of the remaining gauging water (to fine tune concrete consistency) may only be started after two-thirds of the wet mixing time to avoid surplus water in the concrete.

Consumption

Recommended dosage

High flow concrete: 0.4 - 1.5 % by weight of binder

Self Compacting Concrete (SCC): 1.6 - 2.2 % by weight of binder

Dosages outside of these ranges can be used depending on the mix design, raw materials, climatic conditions and concrete requirements. Trial mixes must be performed to establish the exact dosage rate required.
