SikaPlast®-208 PC

HIGH RANGE WATER-REDUCING ADMIXTURE FOR EARLY STRENGTH CONCRETE

SikaPlast® -208 PC is a 3rd generation PCE based high performance superplasticizer for producing soft consistency concrete.
SikaPlast®-208 PC meets the requirements of EN 934 - 2 and ASTM C 494
Type E,
 

SikaPlast®-208 PC combines different modes of actions. By adsorption on the surface of the fines and keeping them apart while the hydration is in progress, SikaPlast®-208 PC effects the following concrete properties:
  • Long slump retention and High - range water reduction
  • High flowability (considerably reduced placing and compacting work)
  • Improved creep and shrinkage resistance characteristics
  • When used at higher dosages, SikaPlast®-208 PC can give extended working time.
  • SikaPlast -208 PC contains no chlorides or other corrosion-inducing substances and can therefore be  used without any restrictions for reinforced concrete structures.
  • High early strengths for precast or early stripping As a water-reducer

Usage

SikaPlast® - 208 PC is used as a superplasticiser in the production of free flowing concrete for:
▪ All precast concrete
▪ Slabs and foundations
▪ Walls, columns and piers ▪ High strength concrete
▪ High durability concrete (low w/c ratio)
▪ High strength and durable precast products

Application

Application Information

Compatibility

SikaPlast -208 PC may be combined with all Plastocrete , Sika Aer, Sika ® Pump, Sikacrete PP-1 products, but must be added separately to the mix and not pre-mixed prior to its addition. SikaPlast -208 PC is compatible with all portland cement types.

Dispensing

SikaPlast®-208 PC is added to the gauging water prior to its addition to the dry mix or added separately to the wetted concrete mix.
For optimum utilisation 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 con- sistency this should be done after a minimum of 2/3 of the wet mixing time to avoid surplus water in the concrete.

Restrictions

Overdosing will result in increased workability and setting time of the concrete; however provided that curing is effective, ultimate concrete
strength and properties will not be affected. Use an appropriate concrete mixer and do not mix by hand. Trial mixes are recommended to establish exact dosage rates required to suit individual requirements. Please contact Sika TechnicalDepartment for further assistance.
Consumption

Recommended dosage

0.5 - 2.0 ltr per 100 kg of cement
