Sika® ViscoCrete®-151
HIGH PERFORMANCE CONCRETE SUPERPLASTICISER
DESCRIPTION
Sika® ViscoCrete®-151 is a high performance concrete
superplasticiser based on a blend of 3rd generation
PCE polymers.
Sika® ViscoCrete®-151 meets the requirements of
ASTM C494 Type G.
USES
Sika® ViscoCrete®-151 is suitable for use in the manufacture of concrete for both RMC and precast applications.
Sika® ViscoCrete®-151 can be used for the following
types of concrete:
▪ Precast
– Spun piles
– Square pile
– Hollow core precast
▪ Bridges and cantilever
▪ Slender components with dense reinforcement
▪ Slabs, columns and walls
CHARACTERISTICS / ADVANTAGES
Sika® ViscoCrete®-151 imparts the following concrete
properties:
High fluidity (reduced effort in placing and compacting work)
▪
Improved creep and shrinkage resistance characteristics
▪
Sika® ViscoCrete®-151 contains no chlorides or other
corrosion-inducing substances and can therefore be
used without any restrictions for reinforced concrete
structures.

TECHNICAL INFORMATION
Concreting Guidance Concrete placing: With the use of Sika® ViscoCrete®-151, 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 Sika® ViscoCrete®-151 is added to the mixing water prior to its addition to
the dry mix or added separately to the wetted concrete mix.
For optimum dispersion, we recommend a minimum 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.
