Usage

Sika® ViscoCrete®-30 PowerPack, formulated for applications in cement and special anhydrite binder systems, used in the dry mortar industry to produce flowable screeds and mortars.
  • Dry mortar calcium sulphate flow screeds
  • Binder mixture for construction site flow screeds
  • Cementitious flowable mortar systems
 

Advantages

Sika® ViscoCrete®-30 PowerPack works based on a combination of electrostatic forces and steric repulsion effects. Thus, solid particles can be dispersed effectively.
The benefits include, but are not limited to, the following:
  • High water reduction at low dosage
  • Very good flowability and self-levelling behaviour
  • Reduced mixing times due to rapid adsorption
  • Long-term stability enables long slump life
  • Low influence on hydration
  • Good stabilizing effect
  • Efficiency over a wide pH-range
  • Compatible with other additives, e.g. citric acid
  • Free of formaldehyde and ammonia

Application

Application Information

Dispensing

Sika® ViscoCrete®-30 PowerPack is added to the dry mix. For optimum utilisation of the high water reduction we recommend a minimal wet mixing time of 30 seconds for mortar.

Compatibility

Sika® ViscoCrete®-30 PowerPack may be combined with many other Sika® Products as well as with most existing accelerators, retarders and other additives used in dry-mortar applications. In combination i.e. with Sika® ViscoCrete® Powders improvements in flowability and retardation may be achieved.

Important: Always conduct trials before combining products in specific mixes and contact our technical service for information about specific combinations with Sika products.
Consumption

Recommended dosage

Depending on the application, the dosage of Sika® ViscoCrete®-30 PowerPack varies from 0.1 to 0.2% of the binder content. At high dosage, Sika® ViscoCrete®-30 PowerPack can cause retardation as well as at low temperatures.
