SikaPlast®-204 V

PCE based superplasticizing and set retarding concrete admixture

SikaPlast®-204 V is a 3rd generation polymer based high performance superplasticizer for producing soft consistency concrete.
SikaPlast®-204 V meets the requirements of ASTM C 494 Type D & G.
SikaPlast®-204 V conforms to Type G when used at 1.0 l/kg cement.

SikaPlast®-204 V combines different modes of actions. By adsorption on the surface of the fines and keeping them apart while the hydration is in progress, SikaPlast®-204 V effects the following concrete properties:
  • Long slump keeping and high water reduction
  • High flowability (considerably reduced placing and compacting work)
  • Faster evolution of early strength development
  • Workability can be maintained up to 4-6 hours (still depends on admixture dosage, cement type, temperature)
  • Improved creep and shrinkage resistance characteristics
SikaPlast®-204 V contains neither chlorides nor other corrosion-inducing subsances and can therefore be used without any restrictions for reinforced concrete structures.

Usage

SikaPlast®-204 V is mainly suitable for the manufacture of concrete for RMC plants and site batch concrete.
SikaPlast®-204 V is used for the following types of concrete:
  • High strength bored piles
  • Bridges and cantilever
  • Slender components with dense reinforcement

Technical Information

Concreting Guidance

Concrete Placing: With the use of SikaPlast®-204 V, 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

SikaPlast®-204 V 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 ultra 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

SikaPlast®-204 V 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.
SikaPlast®-204 V is compatible with all Portland Cement types.
