Sika® ViscoCrete®-3168

HIGH RANGE WATER REDUCING CONCRETE ADMIXTURE

Sika® ViscoCrete®-3168 is a 3rd generation polymer based high performance superplasticizer for producing soft consistency high grade concrete.
Sika® ViscoCrete®-3168 meets the requirements of ASTM C 494 Type G.

Sika® ViscoCrete®-3168 combines different modes of actions. By adsorption on the surface of the fines and keeping them apart while the hydration is in progress, Sika® ViscoCrete®-3168 effects the following concrete properties:
  • Extremely high water reduction
  • Producing very soft consistency and suitable for long distance pumping
  • High flowability (considerably reduced placing and compacting work)
  • Workability can be maintained up to 120 minutes (still depends on admixture dosage, cement type, temperature)
  • Highly improved waterproofness
  • Improved creep and shrinkage resistance characteristics

Usage

Sika® ViscoCrete®-3168 is mainly suitable for the manufacture of concrete for RMC and precast batching plants.
Sika® ViscoCrete®-3168 excels by its extremely high water reduction capacity, providing good flow ability while retaining optimal cohesion of the mix.
Sika® ViscoCrete®-3168 is used for the following types of concrete:
  • High-strength / high performance cast on site concrete
  • High early strength for concrete shafts
  • Bridges and cantilever
  • Slender components with dense reinforcement

Technical Information

Concreting Guidance

Concrete placing: With the use of Sika® ViscoCrete®-3168, concrete of highest quality is being produced, however state of the art concrete technology, such as mixing, placing, vibrating and curing must be respected and applied.
Curing: Effective measures for concrete curing must be followed.

Specific Advice

Sika® ViscoCrete®-3168 is added to the gauging water prior to its addition to the dry mix or added separately to the wetted concrete mix.
For optimum utilization of the high range water reducer we recommend a minimum wet mixing time of 60 seconds.
When adding the balance of the batching water to adjust concrete consistency this should be done after a minimum of 2/3 of the wet mixing time to avoid surplus water in the concrete.

Application

Application Information

Compatibility

Sika® ViscoCrete®-3168 may be combined with all Sikament, Sika® Aer, Sika®Pump, Sikacrete® PP-1 products, but must be added separately to the mix and not pre-mixed prior its addition.
Sika® ViscoCrete®-3168 is compatible with all Portland Cement types.
