Sika® ViscoCrete®-556 P is a high-performance superplasticizer and water
reducer in powder form based on Sika® ViscoCrete® polycarboxylate polymer
technology.
USES
Sika® ViscoCrete®-556 P is formulated for applications in systems with high
calcium sulfate content or pure gypsum binders. The product is especially
suitable for the production of dry-mixed mortars and concrete for applications
like:
▪ Building plaster, render, stucco
▪ Gypsum-based self-leveling mortar
▪ Cement-based self-leveling mortar
▪ Grouts, non-shrink grouts, repair mortars
▪ molding plaster, dental & medical plaster
▪ UHPC
High water reduction and excellent flowability have a positive influence on the
above mentioned applications.
Sika® ViscoCrete®-556 P can be used in the following binder systems:
▪ Calcium sulfate binders (α- and β-hemihydrate,
natural/thermal/syntheticanhydrite)
▪ Ternary compounds (Portland cement + calcium aluminate cement +
calcium sulfate)
▪ Portland cement and cement blends, especially cement with high C3A,
sulfate and alkali content
CHARACTERISTICS / ADVANTAGES
The benefits of Sika® ViscoCrete®-556 P include:
▪ High water reduction and Excellent flowability
▪ Low influence on setting time
▪ Increased early strength development
▪ Improved shrinkage and creep behavior
▪ Reduced mixing times due to rapid adsorption
▪ Low influence on hydration
▪ Efficiency over a wide pH-range
▪ Compatible with other additives
▪ Free of formaldehyde (unlike SNF/SMF) and ammonia
▪ Good compatibility with sulfate
CONSUMPTION / DOSAGE
Dosage rate varies depending on the application and due to variations in
drymix composition. A typical dosage range is 0.05 - 0.5 % by weight of binder.
At high dosage bleeding and/or segregation may occur as well as retardation of
setting.
DISPENSING
Sika® ViscoCrete®-556 P is added to the dry mix. For optimal utilization we
recommend a minimal wet mixing time of 30 seconds for mortar.
COMPATIBILITY
Sika® ViscoCrete®-556 P may be combined with many other Sika products as
well as with most existing activators/accelerators, retarders, redispersible
powders, stabilizers and other additives used in dry-mix applications. In
combination i.e. with other Sika ViscoCrete Powders and Retardan
improvements in flowability and setting-time adjustment may be achieved.
