SikaPlast®-398 SF

PCE BASED SUPERPLASTICIZING AND SET RETARDING CONCRETE ADMIXTURE

SikaPlast®-398 SF is a 3rd generation polymer based high performance superplasticizer for producing soft consistency concrete.
SikaPlast®-398 SF meets the requirements of ASTM C494 type D & G.
SikaPlast®-398 SF conforms to type G when used at 0.8 - 1.0% dosage, depending on cement type used.

SikaPlast®-398 SF combines different modes of actions. By adsorption on the surface of the fines and keeping them apart while the hydration is in progress, SikaPlast®-398 SF effects the following concrete properties:
  • Long slump keeping and high water reduction
  • Compatible with SCM like GGBSF, PFA
  • High flowability (considerably reduced placing and compacting work)
  • Faster evolution of early strength development
  • Workability can be maintained up to 3-6 hours (still depends on admixture dosage, cement type, temperature)
  • Improved creep and shrinkage resistance characteristics
  • When used at higher dosages, SikaPlast®-398 SF can give extended working time

Technical Information

Concreting Guidance

Concrete placing: With the use of SikaPlast®-398 SF, 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®-398 SF 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

SikaPlast®-398 SF 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®-398 SF is compatible with all Portland Cement types.
