Description

SikaPlast®-209 H KH
PCE BASED SUPERPLASTICIZING AND SET RETARDING CONCRETE ADMIXTURE
DESCRIPTION
SikaPlast®-209 H KH is a 3rd generation polymer based
high performance super plasticizer for producing soft
consistency concrete.
USES
SikaPlast®-209 H KH is mainly suitable for the manufacture of concrete for RMC plants and site batch
concrete SikaPlast®-209 H KH is used for the following
types of concrete:
▪ High strength Bored piles
▪ Bridges and cantilever
▪ Slender components with dense reinforcement
CHARACTERISTICS / ADVANTAGES
SikaPlast®-209 H KH combines different modes of actions. By adsorption on the surface of the fines and
keeping them apart while the hydration is in
progress, SikaPlast®-209 H KH 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®-209 H KH contains neither chlorides nor
other corrosion-inducing substances and can therefore be used without any restrictions for reinforced
concrete structures.
▪
APPROVALS / CERTIFICATES
SikaPlast®-209 H KH meets the requirements of ASTM
C494 Type G.

Compatibility SikaPlast®-209 H KH may be combined with all Sikament, Sika® Aer, Sika®
Pump,Sikacrete® PP1 products, but must be added separately to the mix
and
not premixed prior its addition.
SikaPlast®-209 H KH is compatible with all Portland Cement types.
Dispensing SikaPlast®-209 H KH is added to the gauging water prior to its addition to
the dry mix or added separately to the wetted concrete mix. For optimum
utilizationof the ultrahigh 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.
