SikaPlast®-204 L

PCE BASED SUPERPLASTICING AND SET RETARDING CONCRETE ADMIXTURE

SikaPlast®-204 L is a third generation polymer based high performance superplasticizer for producing soft consistency concrete.

SikaPlast®-204 L combines diffent modes of actions.
By adsorption on the surface of the fines and keeping them apart while the hydration is in progress,
SikaPlast®-204 L 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 hours (still depends on admixture dosage, cement type, temperature, W/C)
  • Improved creep resistance and shrinkage resistance characteristics
SikaPlast®-204 L contains neither chlorides nor other corrosion-inducing subsances and can therefore be used without any restrictions for reinforced concrete structures.

Usage

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

Application

Application Information

Dispensing

SikaPlast®-204 L 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.

Compatibility

SikaPlast®-204 L may be combined with all Sikament®, Sika® Aer, SikaPump®, Sikacrete® PP1 products, but must be added separately to the mix and not pre-mixed prior its addition.

SikaPlast®-204 L is compatible with all types of Portland Cement, including S.R.C type and Hydraulic Cement.
Consumption

Recommended dosage

0.6 - 1.6 l per 100 kg of cement or cementitious weight.Typical 0.8 - 1.2 l per 100 kg.
