Sika® ViscoCrete®-120 P

High-performance superplasticizer for high early strength

Sika® ViscoCrete®-120 P is a high-performance superplasticizer in powder form, based on Sika® ViscoCrete® polycarboxylate (PCE) polymer technology.

Sika® ViscoCrete®-120 P is adsorbed onto the surface of the binder particles and due to repulsive forces from the effect known as steric hindrance, the solid binder particles are very effectively dispersed in the mix. The characteristics and advantages of Sika® ViscoCrete®-120 P include:
  • High early strength development despite cement reduction
  • High water reduction at low dosage
  • Fast adsorption
  • Good stability without stickiness
  • Improved shrinkage and creep behaviour
  • No influence on the setting times
  • Good compatibility with other additives
  • Free of formaldehyde and ammonia

Usage

Sika® ViscoCrete®-120 P is formulated for use in dry mortar applications and can be used with different hydraulic binder systems:
  • Portland cement (OPC)
  • Clinker-reduced and alternative binders
  • Ternary blended binders (depending on required performance)
Sika® ViscoCrete®-120 P is especially suitable for the following dry-mortar applications:
  • Grouts (including non-shrink grouts)
  • Repair mortars
  • Tile adhesives
  • 3-D-printing mortar
  • Cementitious screeds and levelling compounds

Application

Application Information

Dispensing

Sika® ViscoCrete®-120 P is added to the dry mix. For optimum utilisation of the high water reduction capability, a minimum wet mixing time of 30 seconds is recommended for the mortar before use.

Compatibility

Sika® ViscoCrete®-120 P 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 these combinations with Sika® ViscoCrete®-120 P, additional improvements in flow and retardation may also be achieved.
Important: Always conduct trials before combining products in specific mix designs and contact our Technical Services Department for any additional information and advice concerning specific combinations with other products.
Consumption

Recommended dosage

Depending on application dosage rate of Sika® ViscoCrete®-120 P is between 0.05 and 0.5 % by weight of binder. At high dosage and at low temperatures, Sika® ViscoCrete®-120 P can also cause retardation.
