Sika® ViscoCrete®-20 HE PK – 200 LTRS DRUM | NASIR & SONS | SIKA PAKISTAN

High Range Water Reducing / Superplasticizing Concrete Admixture

USES

Sika® ViscoCrete®-20 HE PK is especially suitable for
the production of concrete mixes which require
high early strength development, powerful water
reduction and excellent flowability.
Sika® ViscoCrete®-20 HE PK is mainly used for the
following applications:
▪ Pre-cast concrete
▪ Fast track concrete
▪ In situ concrete requiring fast stripping time
▪ Self Compacting Concrete (SCC)

CHARACTERISTICS / ADVANTAGES

Sika® ViscoCrete®-20 HE PK as a powerful superplasticizer
acts by different mechanisms.
Through surface adsorption and sterical effects
separating the binder particles the following
properties are achieved:
Pronounced increase in the early strength development,
resulting in very economic stripping
times for pre-cast and in situ concrete
▪
Extremely powerful water reduction; > 20%, resulting
in high density, high strengths and reduced
water permeability etc.
▪
Excellent plasticizing effect, resulting in improved
flowability, placing and compacting behavior
▪
Reduced energy cost for steam cured pre-cast
elements
▪
Especially suitable for the production of Self
Compacting Concrete (SCC)
▪
▪ Improved shrinkage and creep behavior
Reduced closure times for repairs of roads and
runways
▪
Sika® ViscoCrete®-20 HE PK does not contain chlorides
or other ingredients which promote the corrosion
of steel reinforcement. It is therefore suitable
for reinforced and pre-stressed steel.

APPROVALS / STANDARDS

Sika® ViscoCrete®-20 HE PK follows the requirements
